OK, on Thursday I got infected with the Win32/Patched.FM and Win32/Patched.FL virus which has affected winlogon.exe and explorer.exe (kind of important files). The AVG resident shield picked it up but was unable to do anything about it and it was popping up all kinds of rubbish messages and websites. I had to hard power off my machine initially and went into safe mode to try and get past the initial problems via my AVG free 9.0 safe mode scan, then used my other computer to get onto this forum and check out the process to take in tackling it. The result is that I set it up for normal boot mode, and went through the full process as described for my computer (Windows XP Professional 32-bit). The only bit that appeared to fail entirely was the Root Repeal which didn't load even though I did disable virus checker and firewall beforehand. Logs are attached. The problem seems to be 'contained' now but I'm still infected through winlogon.exe and explorer.exe and now I've enabled the AVG resident shield again after the diagnostics it's flagging those two files every few seconds. Any help on sorting it out gratefully received. Thanks.
