hi out thre, im using vista dual boot with xp on it, that means i have xp and vista, so now my xp is installed with kaspersky anti virus, but vista without anti virus, i would like to know can i install to different anti virus into the same computer, btw, my vista and xp are on the same hard disk but different partition.

i also using dual boot..i use kaspersky and install in windows xp...when on win XP,i doing full scan..in vista,i dont use AV.

im doing the same right now, not using av in vista, but will it get infected?

On your Vista, is your UAC on? If yes then it should be OK. But an AV program is still recommended.

UAC? whats that
