I found this solution for the problem here: http://www.bleepingcomputer.com/virus-removal/remove-antimalware-doctor
So I downloaded Rkill and followed the steps it said. I started up my computer ran Rkill the moment that AntiMalware Doctor popped up. It seemed to close most things but there were still a few fake alerts it seemed so I ran it again. I then started scanning with MalwareBytes and not long afterward AVG popped up a security warning telling me repeatedly that winlogon.exe and explorer.exe were infected with trojan horse Patched_c.cC** the *'s being varying letters. AVG also told me that the files were white-listed and couldn't be removed, note that this was before I had pressed anything.
I waited until MalwareBytes was done and then removed everything it could. Then I looked back and AVG said it needed to restart the system to fix the problems with winlogon.exe and explorer.exe. I figured something must seriously be wrong because each one was listed repeatedly very many times. So I hit okay on the restart and then after the XP bootscreen it just goes black and then after a brief pause and it reboots and repeats the cycle all over again. One of the times it did this I noticed a BSOD flash by for half a second before it auto restarted.
I believe AVG deleted winlogon.exe and explorer.exe and now my computer is incapable of starting up fully. I tried Safe Mode and it didn't work either. I have my original XP install disc and I think all I may need to do to repair my system so it starts up is copy a fresh winlogon.exe and explorer.exe to my hard drive off the disc in Recovery Console. The problem is I can't remember the proper commands nor do I know the location of the files on the disc or where they should go on the hard drive.
I'm not sure what my disc drive's letter ID is either if anyone could tell me how I could find that.
Thanks for the help.
