Tech support scammers now use “CRITICAL ALERT FROM WINDOWS” fake pop-ups to scam people for money

“CRITICAL ALERT FROM WINDOWS” fake pop-up is a deceptive message that might appear on your screen after entering a phishing website[1]. Tech support scammers[2] control such websites and deliver misleading messages to scare unsuspecting and inexperienced computer users.

The false message “informs” the victim that the computer has been blocked because “Windows has detected some suspicious activity from your IP address.” The alert falsely claims that virus or spyware has caused a security breach at victim’s network location, which is absolute nonsense.

Traditionally, the alert urges the victim to call a number provided in order to get help from “engineers” that ostensibly can walk the victim through the malware removal process via phone. If you're looking for honest malware removal guides, we invite you to visit sites such as DieViren[3] instead.

You should never call these scammers because sooner or later they will ask you to provide remote access to your computer or buy some useless software pack to fix imaginary issues.
