I’ve been having this problem for a while. Every time I’m away from my computer for 30 min or more, when I come back, there’s a window in the lower right corner which Norton is conducting some background tasks. Every time this window pops up, my computer freezes. I’m running Windows Vista Home Premium Service Pack 2. I don’t know which version of NIS I have, because I can’t figure out where to look for that information. Any help is appreciated.
