Okay, so, say I have parallells on a MBP, and am running XP and OSx similtaniously....On my XP side I will be using some programs such as PeerGuardian2 and "Hide My IP 2007" or simular software...Will the fact that i'm running XP and OSX similtaniously have and affect of the effectiveness of those programs? Also, If I get a virus on XP, can it affect OSX in any way? Or, if someone hacks into XP, can they hack into OSX? Or is it literally like having 2 different computers with two different IP addresses? thanks.
