|I would suggest in any case, to scan your machine with this Rescue System.|
In that case, no virus or trojan is running and can hide itself or block some processes, necessary to remove the virus or trojan.
You might also get in trouble, if your antivirus software has already been infected and shows, that there were no virus found.
The CD cannot be infected, the anvirus updates itself to ram and starts scanning with the most current virus definition files.
It does not install anything to your PC.
It only works from CD or RAM.
