Fake antivirus software has emerged as one of the most persistent and insidious threats in the cybersecurity landscape, preying on users’ legitimate concerns about malware protection while simultaneously installing the very threats they claim to prevent. These deceptive programs, commonly referred to as “scareware” or rogue antivirus software, operate through sophisticated social engineering tactics designed to manipulate users into making hasty security decisions based on fear and urgency. The threat is particularly concerning because it exploits the growing awareness among internet users that antivirus protection is essential for digital safety, turning this knowledge into a weapon against them. Understanding the mechanisms of fake antivirus attacks and implementing comprehensive protective strategies has become absolutely critical for anyone using digital devices in today’s threat-filled environment.
Understanding the Nature and Operations of Fake Antivirus Software
Fake antivirus software fundamentally represents a category of malware that masquerades as legitimate security protection while actually introducing malicious code and stealing personal information from victims. These programs are specifically engineered to create a false sense of security while systematically compromising device integrity and user privacy. The term “scareware” accurately describes these threats because their primary operational strategy involves psychological manipulation through fear-based messaging that pressures users into immediate action without critical thinking or verification.
The operational structure of fake antivirus programs typically begins with what security experts call a “hook”—often a pop-up window that appears while users browse the internet, claiming to have detected various threats on their computers. These pop-ups display alarming messages such as “Your computer is infected with a dangerous virus!” or “Immediate action required to prevent data loss!” designed to trigger panic responses rather than rational decision-making. The psychological pressure intensifies through visual elements including flashing red screens, threatening graphics, and increasingly aggressive notifications that make it seem as though the user’s device is under active attack. This sensory overload deliberately prevents users from thinking clearly enough to question the legitimacy of the warnings they are receiving.
Once a user falls for the initial pop-up and clicks on the malicious link or download button, several harmful outcomes can occur nearly simultaneously. The fake antivirus may install itself directly onto the device, displaying fabricated scan results claiming to have found dozens or even hundreds of infections that do not actually exist. Financial theft represents one major consequence, as users are then pressured to pay between $50 and $100 or more for the “full version” of the fake software that will supposedly remove these phantom threats. Beyond financial exploitation, the downloaded software often disables legitimate antivirus protection that may already exist on the device, making the system vulnerable to genuine malware infections. Additionally, the fake antivirus program itself frequently contains spyware, keyloggers, or trojans that enable attackers to steal passwords, banking information, credit card details, and other sensitive personal data.
The technical sophistication of fake antivirus programs has evolved significantly over time, particularly in how they disguise themselves as authentic security software. Early versions were often crude imitations that used generic names and obviously fraudulent interfaces, but modern variants employ much more convincing designs that closely mimic genuine antivirus products from trusted companies like McAfee, Norton, Avast, and AVG. Some fake antiviruses even reproduce legitimate company logos, user interface designs, and scanning displays so convincingly that distinguishing them from authentic software requires careful scrutiny. Cybercriminals achieve this level of verisimilitude by studying screenshots and video demonstrations of real antivirus software, then recreating the visual experience in their fraudulent programs to increase credibility and reduce user suspicion.
Recognition and Identification of Fake Antivirus Alerts
Successfully protecting yourself against fake antivirus software begins with developing the ability to distinguish fraudulent warnings from legitimate security alerts, a skill that requires understanding the specific characteristics that differentiate scareware from genuine protection. Legitimate security software operates within clear parameters and exhibits specific behavioral patterns, while fake antivirus programs consistently display red flags that become recognizable once users know what to observe. The first and most obvious indicator involves the source and nature of the alert itself.
Alarming and urgent language represents a primary distinguishing factor between fake and genuine virus warnings. Legitimate antivirus software, developed by professional security companies with legal and ethical responsibilities, uses neutral and factual language when reporting actual threats. Phrases like “Critical threat detected” or “Your computer will fail unless you act immediately” are characteristic of scareware, which relies on fear and urgency to short-circuit rational thinking. In contrast, genuine security software provides specific details about detected threats, including the file names, file paths, and technical classifications of actual malware, allowing knowledgeable users to verify the information independently. Fake antivirus warnings typically use vague, generic language that cannot be verified or investigated further, as the threats they claim to have detected simply do not exist.
Unprompted pop-ups and unsolicited warnings present another critical red flag for identifying fake antivirus software. Authentic antivirus programs installed on a user’s device send notifications through their own interfaces or system notifications rather than through web browser pop-ups, which are notoriously untrustworthy and easily spoofed by malicious websites. If a security warning appears in a browser window without the user having initiated any scan or action, and especially if this warning appears to come from an antivirus program the user did not install, this represents a major warning sign of scareware. Additionally, legitimate antivirus software rarely displays pop-ups that try to prevent users from closing them or navigating away. Fake antivirus programs frequently employ “clickjacking” techniques where clicking the close button or canceling the dialog actually triggers the download or installation of malware rather than closing the window as the button’s label suggests.
Poor grammar, spelling errors, and unprofessional design quality often indicate scareware, though this indicator has become less reliable as cybercriminals have improved their technical and creative skills. Many fake antivirus websites and pop-ups still contain noticeable spelling mistakes, grammatical errors, and visual design inconsistencies that would never appear in a professional software company’s product. For example, capitalization might be inconsistent, sentences might be awkwardly constructed, and logos might be subtly distorted versions of legitimate company trademarks. For more information on how to protect yourself from these threats, consult resources like HelloTech’s guide on fake antivirus. However, some modern scareware is professionally designed, so the absence of these surface-level errors should not be used as sole confirmation that a warning is legitimate.
Suspicious web addresses and misleading download buttons provide important clues for identifying fraudulent antivirus software, particularly when users receive alerts through web browsers. Cybercriminals often use URLs with slight misspellings of legitimate antivirus companies or use unusual domain extensions, such as claiming the software is at “www.mcaffee.net” instead of the real “www.mcafee.com.” When downloading software, users should be extremely cautious of web pages that display multiple download buttons, as scammers deliberately create confusion by placing their malicious download buttons prominently while attempting to make legitimate options less obvious. Furthermore, searching for antivirus software through search engines can be risky, as cybercriminals invest money in sponsored search results to make their malicious websites appear as official product pages. The safest approach is to type the official website URL directly into the address bar rather than clicking on search results, which may lead to convincingly fraudulent mirror sites designed to collect personal information or install malware.
Requests for sensitive information, payment, or unusual system changes represent the most serious red flags for identifying fake antivirus software. Legitimate antivirus companies never ask users to download security software through web browser pop-ups or to provide credit card information to resolve detected threats. Authentic antivirus software, if installed, already has the user’s license information and does not require sudden emergency payments to deal with infections. When a pop-up suddenly demands payment information or requests access to financial accounts, this is definitively an indicator of scareware. Similarly, genuine security software will not request usernames and passwords for online accounts, nor will it ask users to disable their existing security protections or firewalls to “improve performance,” tactics commonly used by fake antivirus programs to gain unrestricted system access.
Prevention and Proactive Protection Strategies
Protecting yourself against fake antivirus software requires a multi-layered approach that combines technical protections with behavioral strategies and informed decision-making practices. No single strategy completely eliminates risk, but implementing several complementary protective measures substantially reduces the likelihood of falling victim to scareware attacks. The foundation of this protective strategy rests on maintaining updated software and operating systems, as unpatched vulnerabilities create entry points that cybercriminals exploit to distribute fake antivirus programs and other malware.
Keeping software patched and updated provides the essential first line of defense against malware distribution, including the mechanisms through which fake antivirus programs spread. Security patches released by software manufacturers address known vulnerabilities that cybercriminals actively exploit to compromise systems and install malicious code. When users delay installing available security updates, they leave their devices vulnerable to well-known attacks that newer patches specifically prevent. This applies not only to operating systems like Windows and macOS, but also to web browsers such as Chrome, Firefox, and Edge, as well as plugins like Flash Player, PDF readers, and other commonly used applications. Enabling automatic updates ensures that patches are installed promptly without requiring manual action, though some users prefer to test patches before deployment in organizational environments. For individual users with standard devices, enabling automatic updates represents the most practical approach to maintaining security without requiring constant vigilance about security announcements.
Installing and maintaining legitimate antivirus software provides detection and remediation capabilities that help prevent or quickly address fake antivirus infections. Legitimate antivirus programs use multiple detection methods including signature-based detection that matches malware against known threat databases, heuristic analysis that identifies suspicious behavioral patterns, and machine learning algorithms that recognize novel malware variants based on similarities to known threats. The variety of legitimate options available means that cost should not be a barrier to protection, as reputable free antivirus options now match the capabilities of many paid solutions.Microsoft Defender, which comes built-in with Windows, provides robust protection at no additional cost and performs well in independent testing against modern threats. For macOS users, Intego offers specialized protection, while Android device users benefit from built-in Google Play Protect combined with optional third-party solutions like Bitdefender or Avast. The key is selecting antivirus software from established, reputable companies with proven track records of security effectiveness rather than downloading unknown programs that claim to offer protection, as this approach itself represents a risk vector for encountering scareware.
Implementing pop-up blocking provides an immediate technical defense against one of the primary distribution mechanisms for fake antivirus software. Most modern web browsers include built-in pop-up blockers that prevent websites from automatically opening new windows, and users should verify that these blockers are enabled and set to their highest security level. Pop-up blockers specifically help prevent the initial encounter with scareware by blocking the malicious websites that host fake antivirus alerts and download pages. However, determined cybercriminals sometimes find ways to bypass standard pop-up blockers through technical exploits, so pop-up blocking should be viewed as one component of a broader protective strategy rather than as a complete solution in itself. Additionally, enabling pop-up blocking does not prevent users from accidentally clicking on suspicious links in emails or on social media, so user awareness remains equally important.
Exercising extreme caution with email and email attachments represents an essential behavioral protection strategy against fake antivirus distribution through phishing campaigns. Cybercriminals frequently impersonate legitimate security companies in emails, claiming that the recipient’s antivirus subscription has expired, that security updates are available, or that an urgent security issue has been detected requiring immediate action. These phishing emails typically include links to fraudulent websites hosting scareware or attachments containing malware that installs fake antivirus programs. Users should never click on links in unsolicited emails, even if the email appears to come from a trusted company or familiar contact whose email account may have been compromised. The safest practice is to independently verify any urgent security claims by visiting the official website of the supposed sender by typing the URL directly into the browser address bar, rather than clicking links in emails or messages.
Avoiding suspicious websites and being cautious with downloads prevents the initial malware infection that fake antivirus programs exploit. Websites offering free movies, music, or software, particularly those not affiliated with official distributors or known legitimate sources, frequently host malware including fake antivirus programs alongside their primary offerings. Cybercriminals bundle fake antivirus software with seemingly desirable free downloads to increase installation rates, meaning that downloading “free” content from questionable sources nearly guarantees exposure to malware. Legitimate software should be downloaded exclusively from official vendor websites, authorized resellers, or reputable software repositories, with special caution applied to sponsored search results which cybercriminals frequently manipulate to appear in top search positions. Users downloading files should verify the authenticity of the source, use browser security warnings that alert users to potentially malicious downloads, and conduct internet searches about software before downloading to identify whether it is known scareware.
Maintaining awareness and skepticism about online threats provides perhaps the most important protection against falling victim to fake antivirus scams, as social engineering success ultimately depends on manipulating user psychology. Users who understand that legitimate security companies do not distribute software through unsolicited pop-ups, that antivirus alerts should provide specific technical information rather than vague threats, and that urgent requests for immediate action are tactics employed by scammers are far less likely to click on malicious links or download fraudulent software. Educational initiatives and security awareness training have proven effective at reducing click rates on phishing emails and fraudulent security alerts in organizational settings, with some programs reducing phishing susceptibility from 23% to nearly 1%. The same principles of awareness and skeptical thinking apply to individual users, who should pause and think critically when encountering unexpected security warnings rather than responding immediately based on the fear that such warnings are designed to trigger.

The Psychology and Social Engineering Behind Scareware
Understanding the psychological and social engineering tactics employed by fake antivirus distribution represents a critical component of effective protection, as these tactics exploit fundamental human emotions and cognitive biases that make even technically sophisticated users vulnerable to manipulation. Scareware succeeds not because it represents advanced technical achievement, but because it effectively weaponizes emotions like fear, anxiety, and urgency to override rational thinking processes that would normally lead users to question suspicious claims.
Fear and panic exploitation form the core psychological mechanism underlying scareware attacks, with cybercriminals deliberately designing alarming messages and visual elements to trigger emotional responses that prevent careful analysis. When a user is suddenly confronted with a warning claiming their computer is infected with dangerous malware and that immediate action is required to prevent permanent damage or data loss, the natural human response is to feel threatened and anxious. This emotional state, sometimes called “fight or flight” mode, activates the amygdala in the brain while suppressing higher-order reasoning functions in the prefrontal cortex, making users more likely to take hasty action without considering whether the warning is legitimate. Scareware creators deliberately use language like “Critical threat!” and “Your system will be permanently damaged!” to amplify this effect, creating maximum emotional pressure to download and install the fraudulent software that the scareware claims will solve the problem. The flashing red colors, urgent beeping sounds, and other sensory elements of fake antivirus alerts are specifically designed to heighten panic and override rational skepticism.
Sense of urgency and artificial time pressure represent another psychological mechanism that scareware exploits to bypass user defenses and critical thinking. Users confronted with messages claiming they must act immediately or lose critical data are much more likely to bypass their normal decision-making processes and click on suspicious links without investigating further. By creating the perception that the threat is active and worsening in real-time, and that delays in addressing it will result in catastrophic consequences, cybercriminals pressure victims into immediate action rather than taking time to verify the legitimacy of the warning or seeking advice from trusted sources. This artificial urgency works because most people naturally want to address genuine security threats promptly, and scareware simply exploits this rational instinct by providing false claims of immediate danger.
Social proof and authority manipulation leverage another powerful psychological principle that causes users to believe false claims, particularly when those claims appear to come from authoritative sources or are presented in ways that mimic legitimate communications. Fake antivirus programs succeed partly because they display logos and interfaces that closely resemble well-known security companies like Norton, McAfee, and Avast, which causes users to instinctively trust them based on brand familiarity. When users see a warning that appears to come from Microsoft or their computer’s operating system, they are more likely to trust it than if the same warning came from an unfamiliar source, even if the warning is technically identical. Cybercriminals exploit this tendency by designing their scareware to closely mimic the appearance and messaging style of legitimate security software, causing victims to attribute authority and trustworthiness to fraudulent programs based solely on their visual presentation.
Exploitation of security awareness represents an ironic element of scareware psychology, as the increasing security awareness among internet users about the existence of viruses and malware actually makes them more vulnerable to fake antivirus scams. Users who have learned that they should be concerned about viruses and who recognize the importance of antivirus protection are exactly the type of users most likely to panic when confronted with warnings claiming that their computers are infected. In other words, improved security knowledge becomes weaponized against users by scammers who understand that technically aware users will be more concerned about actual infections and thus more likely to trust warnings about serious threats. This creates a perverse incentive structure where improving user awareness about real threats simultaneously increases their vulnerability to false threat warnings that exploit this awareness.
Technical Protection Mechanisms and System Security
Beyond behavioral and awareness-based protections, users can implement several technical mechanisms that detect and prevent fake antivirus distribution and infection at the system level, reducing dependence on user decision-making in the moment of threat exposure. Modern operating systems and browsers include multiple technical safeguards designed to prevent malware installation, though users must ensure these protections are properly configured and maintained.
Browser security features including safe browsing warnings, pop-up blockers, and malware detection algorithms provide technical defenses against accessing websites hosting fake antivirus software. Google Chrome, Microsoft Edge, and Firefox all include Safe Browsing features that check websites against databases of known malicious sites and alert users when they attempt to visit pages hosting malware or conducting phishing attacks. These warnings are not foolproof, as new malicious sites are created constantly and legitimate sites can be hacked to host malware, but they provide meaningful protection against many common threat sources. Pop-up blockers, enabled by default in modern browsers, prevent automatic opening of new windows that frequently host fake antivirus alerts, though sophisticated attackers sometimes find workarounds to defeat these protections. Users who encounter persistent pop-ups even with blockers enabled should investigate whether malicious browser extensions or browser hijacking software has compromised their systems, as this represents an advanced infection that may require more intensive remediation than simple pop-up blocking.
Windows Defender and built-in system security features provide baseline malware protection on Windows devices without requiring additional software installation, addressing a primary concern about system performance degradation that some users cite as barriers to antivirus protection. Microsoft Defender Antivirus runs on all Windows devices and provides real-time protection against malware including fake antivirus software, operating through multiple detection mechanisms including signature-based detection, heuristic analysis, and behavioral blocking. The Software Repair and Troubleshooting Service available through Windows system settings provides additional protection for users who suspect infections, and Windows Firewall provides network-level protections that can prevent unauthorized programs from establishing outbound connections or receiving commands from remote servers. These built-in security mechanisms represent substantial baseline protections that do not require users to purchase or configure additional security software, making them particularly valuable for users with limited technical sophistication or constrained budgets.
Firewall technology and network-level protections prevent malicious programs, including fake antivirus software, from communicating with attacker-controlled servers to download additional malware, steal personal information, or receive remote commands. Software firewalls running on individual devices create rules about which programs can establish outbound connections and to which destinations, blocking unauthorized network communications that malware attempts. A properly configured firewall can prevent a fake antivirus program that somehow manages to install itself from exfiltrating stolen passwords or credit card information to remote servers, though this represents defense-in-depth rather than a primary prevention mechanism. Windows Firewall, which comes standard on all Windows systems, provides adequate protection for most users when properly configured, though more advanced users or organizations may benefit from additional firewall solutions with more granular control and monitoring capabilities.
Automatic system restoration and rollback capabilities provide technical options for recovering from infection when other protections fail to prevent scareware installation. Windows includes System Restore functionality that creates “restore points” at regular intervals, capturing the operating system state including registry settings and system files so that the system can be reverted to a previous clean state if malware installation corrupts the system. If users detect scareware infection, initiating a system restore to a point before the infection occurred can remove the malware without requiring manual identification and deletion of malicious files, though this process will also remove any software installed or any legitimate system changes made after the restore point. This represents a last-resort option when normal removal procedures fail, but it can be effective at completely eliminating scareware when other methods prove inadequate, particularly for sophisticated variants that deeply integrate themselves into system files and registry entries.
Response and Remediation When Infection Occurs
Despite implementing comprehensive protective strategies, users may still encounter situations where fake antivirus software successfully infects their systems, requiring knowledge of effective remediation procedures to minimize damage and restore device functionality. The response procedures vary somewhat depending on the specific fake antivirus variant and the degree to which it has compromised system functionality, but several standard approaches address the majority of cases.
Immediate disconnection from networks and the internet represents the first critical step following detection or suspicion of fake antivirus infection, preventing the malicious software from transmitting stolen personal information to attackers or receiving additional malware payloads. A fake antivirus program that has gained initial system access may be actively exfiltrating passwords, credit card numbers, and other sensitive information to remote servers controlled by cybercriminals, and every second the infected device remains connected increases potential damage. Additionally, malware sometimes attempts to spread to other computers on the same network or to mobile devices connected via the same Wi-Fi, so rapid network disconnection protects other devices as well. Users should disable Wi-Fi, disconnect all network cables, and avoid connecting to any networks until remediation is complete and the infection has been confirmed removed.
Running legitimate antimalware and antivirus scans provides the standard removal approach for most fake antivirus infections, using established security software to detect and quarantine or remove malicious files. Malwarebytes, a specialized anti-malware tool with particular effectiveness against fake antivirus programs, provides a free version that can be downloaded on another clean computer and transferred via USB drive to the infected system, then run to detect and remove scareware. Multiple scanning passes may be necessary to fully remove all traces of the malware, particularly if the fake antivirus has installed multiple components or created additional malicious processes. Following initial removal, users should run additional scans with different antivirus engines to ensure complete eradication, as some fake antivirus variants use rootkit technology or other evasion techniques to hide from standard detection mechanisms.
Restarting in Safe Mode simplifies the malware removal process by minimizing the number of programs running on the system, reducing interference from the malicious software and improving the effectiveness of removal tools. Safe Mode with Networking starts Windows with only essential system drivers and services, disabling most installed programs and background processes, which allows antimalware software to access and remove files that might otherwise be protected or locked by the malicious program. The reduction in system processes running simultaneously also improves the speed and responsiveness of the system during the scanning and removal process, though users should note that network connectivity may be limited in Safe Mode depending on how the network drivers initialize. Entering Safe Mode typically requires pressing the F8 key repeatedly during computer startup before Windows begins loading, though the specific procedure varies between Windows versions.
Clearing browser cache, cookies, and browsing data removes traces that scareware may have deposited to facilitate continued attacks or install persistent browser hijacking components. Many fake antivirus programs install malicious browser extensions, redirect browser searches, or modify homepage settings to continue compromising the browser even after the main scareware program is removed. Clearing all browser cache, history, cookies, and temporary files eliminates these traces and resets the browser to a clean state, though users should note that legitimate browser data like saved passwords and bookmarks may be lost if the delete process is not carefully configured. Modern browsers provide options to selectively delete specific data types and time ranges, allowing users to clear malware traces while preserving important data. Following the browser clearing process, users should review installed browser extensions and remove any unfamiliar or suspicious additions, as malicious browser extensions represent one of the most persistent mechanisms through which fake antivirus programs maintain system access after removal attempts.
Complete system restoration or reinstallation represents the most thorough remediation approach, guaranteeing complete removal of all traces of fake antivirus software at the cost of reinstalling the entire operating system and all applications. If initial removal attempts fail, if the infection has severely compromised system stability or function, or if the user simply prefers complete certainty of eradication, backing up important personal files to external storage and then performing a fresh operating system installation eliminates all possibility of residual malware persistence. This approach does require that users maintain backup copies of all important data before performing the reinstallation, as the process will erase all files on the system drive, and that they retain installation media or recovery partitions for their operating system. For users with critical data that cannot be easily recovered, consulting professional data recovery services before performing a full system reinstall may be worthwhile, as these services can retrieve files from the original drive if needed.
Monitoring financial accounts for unauthorized activity becomes essential following detection of fake antivirus infection, as these programs frequently capture credit card numbers, banking credentials, and other financial information. Users should contact their banks and credit card companies to place fraud alerts on their accounts, monitor statements carefully for unauthorized charges, and consider placing a credit freeze with the major credit bureaus to prevent fraudsters from opening new accounts in their names. Changing passwords for all financial accounts and other sensitive services from a clean device (one that was not infected) helps prevent continued unauthorized access, and users should prioritize changing passwords for email accounts first, as email serves as a recovery mechanism for password resets across other services. Continuous monitoring of credit reports through services like those offered by Experian, Equifax, and TransUnion helps detect identity theft attempts that may emerge months after the initial infection.
Education, Awareness Training, and Organizational Approaches
Individual users benefit substantially from security awareness training that provides both technical information about scareware and psychological insights about the social engineering tactics that make users vulnerable to these attacks. Organizational approaches to preventing fake antivirus distribution combine security awareness training with technical controls and establish reporting mechanisms that allow employees to alert security teams when they encounter suspected phishing emails or fraudulent security alerts.
Security awareness training programs significantly reduce organizational vulnerability to scareware and related social engineering attacks through education that helps employees recognize threats and respond appropriately. Effective programs combine multiple content delivery mechanisms including video training, interactive modules, simulated phishing campaigns that provide immediate feedback when employees fall for fake security alerts, and regular awareness reminders that keep security top-of-mind. Organizations that implement comprehensive security awareness training and regularly test employee susceptibility to phishing through simulated attacks report substantial reductions in successful compromises, with some organizations reducing phishing click rates from 33% to less than 1%. The inclusion of psychological principles like understanding how fear and urgency affect decision-making helps employees recognize when they are being manipulated and pause to verify suspicious claims before taking action.
Reporting mechanisms and incident response procedures enable organizations to respond rapidly when employees encounter fake antivirus warnings or phishing emails, preventing widespread distribution of scareware across the organization and improving incident response capabilities. Organizations should establish clear procedures for reporting suspected phishing emails and security alerts, train employees on what constitutes a reportable incident, and ensure that reporting is encouraged without penalty so that employees do not hesitate to flag suspicious items. The FBI’s Internet Crime Complaint Center (IC3) provides a federal reporting mechanism for cyber crimes including fake antivirus scams, allowing victims to contribute to law enforcement efforts to identify and prosecute cybercriminals while helping establish patterns of targeted attacks.
Compliance with cybersecurity regulations increasingly mandates security awareness training and incident response capabilities as baseline security controls, creating organizational incentives to implement comprehensive protection programs beyond what would otherwise be economically justified. Regulations including GDPR, HIPAA, PCI DSS, SOX, and CCPA either require or strongly encourage security awareness training for all employees, creating structured approaches to ensuring that security training reaches the entire workforce rather than remaining optional for interested individuals. Organizations leveraging compliance requirements to justify investment in comprehensive security awareness programs benefit from regulatory alignment while simultaneously protecting themselves against realistic threats including fake antivirus distribution.
