My (limited) experience with malware is...it's not uncommon for various key Windows processes to be killed off (made inaccessible) by various malware items.
My systems never get infected, but it seems that I have friends who have friends with infected systems.
Had a system (friend of a friend) a couple of days ago that appeared to have the Personal Securiy malware item. But I suspect there was more, since I managed to remove that (attached the drive as a secondary to 2d computer, ran Malwarebytes) and reattached the drive to the affected system.
Same restrictions...no access to regedit, no ability to connect to Microsoft, no ability to install or run any programs, no Task Manager on the affected system.
Made two attempts to do repair installs...files appeared to install...screen would hang on "Please Wait" indefinitely on the reboot effort where the new system files get registered, load, etc.
After a few hours of this and another trip to my other system (ran Avira Free, found more malware items) and another, last (unsuccesful) effort at a repair install...I did a clean install and gave the system a clean slate (for the time being). I had fiddled away about 8 hours that I could spent here at the forum, learning and trying to assist.
FWIW: There is no known (to me) product that removes everything, there is no known product that finds all malware...and there is certainly no known product that can undo all the unknown damage that may have been done to the system.
