How Fake Virus Pop-Up Scams Work
You are browsing the web normally when suddenly your screen turns red, a loud alarm sounds, and a box pops up claiming: 'CRITICAL ALERT: Your computer is infected with 5 viruses! Call Microsoft Support at 1-800-XXX-XXXX immediately!'
This is a classic Tech Support Scam. Your computer does not actually have a virus—the webpage is simply a deceptive advertisement designed to panic you into calling a fraudster who will ask for credit card payment to 'fix' your computer.

Key Takeaway
Fake virus alerts are loud, scary web ads. Microsoft and Apple will never display pop-up phone numbers on web pages.
How Scammers Hijack Browser Notifications
Scammers often use sneaky tricks to flood your computer with fake alerts:
• Tricky 'Allow' Prompts: A site asks you to click 'Allow' to prove you are human or watch a video. In reality, you just granted permission for the site to send spam pop-ups.
• Full-Screen Lockouts: Scammers trigger full-screen browser modes so you can't easily see the address bar or close the tab.
• Ad Network Malvertising: Rogue ad networks push scam redirects onto unverified websites.
