Have you ever seen a pop-up like this?

 

⚠️ “Your computer is infected! Call Microsoft Support immediately.”
💀 “Mac OS X has detected spyware. Click here to fix now!”

 

These scary alerts look like they’re from your system… but they’re not.

They’re fake warnings triggered by your browser — and they’re designed to trick you into calling a fake support number or downloading malware.


How It Starts:

 

It usually begins when you:

  • Visit a sketchy website (sometimes even by accident)
  • Click a misleading ad or download
  • Allow “notifications” from a website you shouldn’t trust

 

Once allowed, that site can bombard you with urgent, scary messages — even when your browser is closed.


What These Scams Try to Do:

 

Scammers want you to:

 

📞 Call a fake support line

🧑‍💻 Let them remote into your computer

💳 Pay for fake “virus removal” or bogus security software

🔐 Give them access to sensitive data or accounts

 

They rely on panic. And their goal is profit — not protection.
