I think Fakevimes developers reached their fantasy limit as names of the parasites became not as good as before. Now they called parasite Windows Performance Adviser, and its right after the parasite called Windows Pro Rescuer.. I think Windows Performance Advisor would sound better and more professional for Windows users. Anyway now we have Windows Performance Adviser which is the same parasite as all daily parasites from Fakevimes family.
What is this?
As all of them, it installs itself through the system vulnerabilities. Then pretends to scan the system, finds a lot of infections, and asks to upgrade to full version to remove them. All this is Fake. What you need to do is to remove Windows Performance Adviser itself.
As always, I will give the link to Windows Performance Adviser removal instructions, because duplicate them here makes no sense.
