Cleaning windows viruses from linux

Clamav can do this

As noted below, clam is included on a bunch of live CDs and usb bootable Linuxes (TRK) so you can check your windows machine without having to install anything on Windows.

Bitdefender has a Rescue Disk that boots into Knoppix and scans from there. You could either try ripping BitDefender from the disk, or just use that..

This is what I use:

license is free for a year and reneweable, I have been using this for a while now.

Easy to install on Linux partition or Unix partition and easy to scan your mounted C: drive or other media, in addition to other binaries.

ClamAV can do the same but I think for simplicity and just scanning binaries I like how Bitdefender handles this, don't forget you have options on Linux or Unix, you can install both or just opt out and use which ever you think works best for you and your environment.
