An anonymous reader writes "Not trusting Windows's security, I'm never running that OS on the bare-metal. I only run Windows from VMWare, QEMU and now Xen (and, no, I don't play games). With those three emulation/virtualization solutions, it's possible to mount the Windows filesystem from Linux. Presuming I know to mount the Windows filesystem from Linux, how do I do to scan this filesystem from Linux? Are there good free anti-viruses for Linux that will find Windows viruses and trojan and whatnot? If there aren't any, would installing a good anti-virus under Wine be an option? Or could I use *another* virtual Windows OS to which I'd 'hook' the filesystem I want to scan (for example making the system I want to scan's "C:" drive available as the D: drive on a known "good" Windows system)? How should I go about this? What are the gotchas? For example can the registry of an offline system be scanned, the MBR, etc.? I'd like to know how fellow /.ers solved that problem."
