Here’s a thread on how to install AntiVir in Linux. The problem is that live CDs generally don’t allow you to install a program and have it be there next time you boot up. However, I was able to install AntiVir in Puppy Linux which saves your sessions for the next time you boot up, making it ideal for this purpose.

what if you took a regular Live CD like a Kubuntu (to boot into), could you then download and run these AV files without having to re-burn CD’s all the time?

I would guess that the Avira Rescue CD doesn’t delete files which are known to be essential for Windows to boot up, such as explorer.exe. You can get around this by deleting them manually with a Linux live CD or one of the other rescue CDs mentioned above which includes a file manager, then replacing them with files from another healthy Windows install as you did. However, with the amount of work that can take, it makes more sense to me to simply reinstall Windows – though I recommend doing that any time you find out your system is infected.

anyway, some viruses inject some of their code onto important files like explorer.exe and networking services.i deleted those files and the other virus files with a full minimal linux distribution(coz avira wont delete em).

one time i had to take files from another windows installation on another computer..

i blogged about this.. go check it out.. ^^
