I have posted several times concerning my gf's screwed up computer. It is finally so screwed up I can't fix it without a complete reinstall. Since I am tired of fixing it and getting yelled at because it "doesn't work", I thought setting up a dual boot with Ubuntu might solve the problem at least in part. If I have them use Linux to surf the net how big of an idiot do you need to be to get a virus? And will Windows be immune while the computer is booted into Linux?
