Yesterday, I discovered I'd been infected by the Windows Restore bug. We followed removal instructions according to the Bleeping Computer guide here:
After 1 quick scan and 1 full scan by Malwarebytes, my system seemed to be clean. I confirmed this by running more full scans on Malwarebytes and Microsoft Security Essentials. Both came up empty.
Except I'm still having major problems that did not exist before the virus.
(1) My pc crashes and becomes completely unusable after a while. It doesn't seem to be after a fixed duration of time and seems unrelated to what I'm doing on the pc.
(2) All functions are very sluggish. Browsers take too long to open, right-click menus take too long to appear, spreadsheets take forever to load. I have reasonably decent hardware (quad-core cpu, 4gb RAM) and have not experienced such slowness before yesterday.
(3) If I try to boot the PC in Safe Mode, it hangs before/while/after (I'm not sure which) loading this specific file 'crcdisk.sys'. So basically safe mode is unavailable.
I'm pretty much at my wit's end and would appreciate any help.
