Well...at first, Combofix did not appear to be working properly. I basically is getting to stage 3, then completely hanging. The computer hard drives shut down, and the whole pc will sit there until I manually shut down the script and restart the PC.
I then tried in Safe Mode, with the same result, however, with an added twist. The second attempt in Safe Mode yielded a pop up screen in combofix that said the installation had become compromised and not to use it. It mentioned a script altering virus named Virut (?) had potentially compromised the script, and to re-download.
I re-downloaded the script and re-ran in safe-mode, however, I'm still gettting the same freezing at stage 3.
