My computer was infected with the "Internet Security 2010" virus. I ran AVG and it appeared to take care of the problem, but when I tried to reboot, I couldn't log on to Windows. It asked for my Windows password and appeared that it was going to log on, but it immediately closes back out to the logon screen. I then rebooted in safe mode and was able to access my desktop. I ran AVG again and it found I think 4 trojan viruses. I still could not log on to windows. Now, I can't even log on in safe mode, it's like the virus is learning if that makes any sense. I am familiar with combofix and have used it with success in the past. My problem is how do I run it when I can't even log on? I have downloaded it to a cd but don't know how to run it? Is it possible? Thanks.
