If you get to the point where it doesn't let you boot up the PC at all, you know the Virus has won, I had that and I ended up reinstalling my OS.
Not true, mate, I had that same issue a couple of months back. It was also redirecting Firefox so I couldn't search for a solution. I switched to IE instead, Googled the exact virus name and found out what it was. Managed to download a program called TDSSKiller that's a stinger for that specific virus. Job done.
Been trying to run it for over an hour now took me a long time to get shot of avg because it was blocking it now when i try to run it i keep getting a message cannot rename combofik then it shuts down ,,, any ideas.
Rename it? Sorry mate, never seen that before, it's usually my fall-back program that I can rely on if things get screwy.
Make sure that the file you downloaded it called 'ComboFix.exe'. If not, right click and rename it to that then double click to run it.
Can't stand AVG by the way, never got on with it.
