Unable to determine if this is an infection or not. 2 separate symptoms, but started at about the same time. 1st, the SVCHOST service is taking an inordinate amount of CPU time - 25%, pretty steady, and the computer is running hot. I've used ProcessExplorer to try to see what's running in that instance of Svchost, but it seems to vary. Inconclusive. I can shut down that instance of Svchost from TaskManager, but it starts right back up in a minute or 2.
2nd - Windows update won't run. Initially it was hanging on 0%. I tried some "remedies" I found online, including deleting the downloads folder, but that seems to have made it worse.
These are the 2 main things, plus lots of other minor disturbances in the force. (Icons missing, MBAM mysteriously uninstalled, etc).
Ran malware scans with ZoneAlarm, and Malwarebytes - nuthin.
Any help appreciated!
