Author: [Your Name] Date: April 14, 2026 Subject: Cybersecurity & End-User Threat Awareness 1. Abstract Fake antivirus pop-ups, also known as “scareware,” represent a persistent and evolving form of social engineering attack. These deceptive interfaces mimic legitimate security software alerts to manipulate users into taking harmful actions, such as downloading malware, making unnecessary payments, or granting remote access to attackers. This paper analyzes the operational mechanics of fake AV pop-ups, their psychological underpinnings, the technical infrastructure that supports them, and effective mitigation strategies. It concludes that user education combined with technical controls (ad-blockers, endpoint detection) remains the most effective defense. 2. Introduction The trust users place in security notifications is a critical component of modern computing hygiene. Attackers exploit this trust by creating visually convincing pop-ups that warn of fictitious infections. Unlike traditional malware that exploits software vulnerabilities, fake antivirus alerts exploit human vulnerabilities—urgency, fear, and the desire to protect one’s system. These attacks have evolved from crude browser-based pop-ups to sophisticated, full-screen browser locks and phone system integrations. 3. Mechanisms of Operation Fake antivirus pop-ups typically follow a four-stage attack chain: fake antivirus pop up

Deception | System scan simulation showing “detected” threats (e.g., Trojans, registry errors) | Belief that device is severely infected | | 4. Call to Action | Buttons to “Remove Now,” “Renew License,” or “Call Support” | Urgent need to remediate | | Action by User | Resulting Payload |
