This is really bad. I've used a conversion program called Super in the past and needed to convert some video files. When I ran it from desktop, it said it would no longer run and stated I needed the free upgrade (with option to buy an ad-free version). I downloaded the free update, installed it, and life has been a pain ever since. CPU usage really high. Task manager shows offending process(es), but no name for it. Anonymizer also appears in the task list. Running Malwarebytes and quarantining, rebooting doesn't help because the problem reappears. Running Microsoft's Malicious Software Removal Tool doesn't get rid of it either.
I downloaded FRST64 and that won't complete running! If I run it immediately after the Windows login screen it starts scanning but then disappears as said unknown process apparently loads and kills it. If I try to start it again (right click, run as administrator OR just double click), the FRST window flashes on the screen for a nanosecond and disappears. It seems the malware is killing it. Same happens for adwcleaner 126.96.36.199.: a window flashes on the screen for a moment (presumbably loading) and then nothing. FRST generated a FRST.txt file (no additions.txt file) - I'm attaching it as "FRSTdesktop.txt"
I created a recovery drive on another Win 10 Pro computer, and copied frst64 to it. I then rebooted the infected computer into the recovery environment and ran frst64. It doesn't have the option box for Addition.txt. I'm attaching what it did produce as FRSTrecoverydrive.txt.
I'm also attaching the Malwarebytes files. It shows, among other things, Adware.Vitruvian.PrxySvrRST, HKU\S-1-5-21-1831771387-2475998928-3974900432-1000\SOFTWARE\MICROSOFT\WINDOWS\CURRENTVERSION\INTERNET SETTINGS|PROXYENABLE, Removal Failed, , [-1],0.0.0
This infection is really bad. If you can fix this one, I think you should be entered into the Antivirus Hall of Fame!
P.S. I also noticed some unwanted files were added to the desktop. Screen shot attached showing these files from 04-27-18
