Microsoft has a program called “Malicious Software Removal Tool” that’s probably okay—not that we’d particularly recommend it, but at least it’s real. The fake Microsoft Windows Malicious Software Removal Tool is a different story; in the mold of classic fake antispyware, it sneaks into your computer and tries to scam money out of you.
If you can’t tell whether the pop-ups on your computer are real or fake, take a closer look. If you see misspelled text like “Malicious software was detected and partitialy removed” and the program warns of made-up stuff like Spyware.ActivityKey and Keylogger.Stawin, then you have the fake one.
Let’s do Microsoft a favor and squash this imposter. Let STOPzilla do its thing, and you’ll soon be free.
