I've had symptoms, I've seen the HELPDECRYPT files with payment instructions to recover the files. I think I dealt with it. I haven't seen any new files being encrypted, and my MBAM scans show up fine.
However a few things don't seem to work anymore on my computer. Windows update doesn't work anymore. It tells me the service is not running and that I need to restart the computer.
Skype doesn't work anymore, crashes during login. I've tried reinstalling older versions but it still does the same thing.
And explorer won't start in safe mode.
How do I know what files might have been encrypted/damaged (potentially by other malware I had). which might be causing these problems?
