Aliases: No associated aliases

Summary

Windows Defender detects and removes this threat.

This rogue security website pretends to scan your PC for malware, and often report lots of infections. It will say you have to pay for it before it can fully clean your PC.

Even if you do pay, it won't do anything because your PC isn't actually infected with all that malware it "found".

Find out ways that malware can get on your PC.
