Sophos Scans VMs ?

Because Parallels stores its files on the host Mac filesystem, SAV for Mac does indeed scan the contents of a Parallels XP guest.  Any partition that is readable by the host OS will be scanned.  Any that are in a proprietary format will likely be ignored.

Running two AV products on the same files at the same time is generally a bad idea -- so if you have Parallels set up to store all files on the Mac host, then you should either exclude that directory from on-access scans, or use SAV for Mac as your AV scanner, and a void running something else in Windows.  You should still have a decent firewall system in place as well, however (and you can run other AV scanners in non-on-access mode).
