If I am running a computer with a hard drive that has 2 partitions, one with Win XP and one with Vista?

do I need separate anti-virus software for each OS?


Or will the anti-virus software on the XP partition cover everything?

You need separate antivirus installs, one on each. When you're booted to XP anything you've installed while booted to Vista either won't work properly or at all. Conversely, when you're booted to Vista anything you've installed from within XP will be unavailable to Vista. Registry edits are only made to the OS booted, so the dormant OS's registry remains unchanged by installing software on the active OS. Any software that requires those registry edits (and most do) won't run if the edits are in the dormant OS's registry.




If the AV program is installed to both operating systems, and it can run in both XP and Vista (some programs can, some can't), it'll run un either one. (You can install it to the same partition for both operating systems, saving a little disk space, but it has to be installed twice - once in each.)
