Recently I found my computer was running slow and then I downloaded and installed Malwarebytes, after scanning my computer, it detected a bunch of PUM.Hijack.StartMenu viruses along with other PUP viruses. I tried to remove all of them, however they just kept coming back after restart. Also I tried to do a system restore but it was unsuccessful. How do I get rid of this virus? Any help is appreciated.
