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.

However, it hasn't really detected any malware at all and isn't really an antivirus or antimalware scanner. It just looks like one so you'll send money to the people who made the rogue. The websites use product names or logos that unlawfully impersonate Microsoft products.
