I read over some of the other cryptor remedies and tried a couple things, but can't make any progress.
First the symptoms. When I do a search from yahoo.com using Firefox, I get a list of search results. When I click on a search
result link, instead of taking me to the link, it changes the link to something else.
I ran AVG, and it finds the Cryptor virus, but can't delete it. It is showing Cryptor virus in svchost.exe in system32 directory.
I tried running Malwarebytes, and it reads clean. I ran ComboFix.exe, following the instructions, and the computer beeps, and it says AVG is
running, and I need to disable it first, so I stop AVG, and it keeps giving me a warning. I tried stopping all AVG processes with
the taskmanager, and it keeps restarting them afterwards and creating duplicates of AVG processes in the task manager.
Next, I reboot, and start in safe mode, check that AVG is not running in task manager, and when running ComboFix, it still tells me
AVG is running and run at my own risk. I tried to continue, and it says ComboFix may be corrupted and to try getting a new
copy. I tried both links to re-download ComboFix, and it acts the same.
What to do now. This is AMD sempron based with XP home edition.
