I just started working in PhotoShop 7 (better late then
never) and after about 5 min of playing around my system
shuts off.  My screen goes black and the processor seams
to stop responding.  Now I though I may have a
virus/trojan/worm, however I have the latest Def's and
have run the removal tools for the last 3 nasties that
have just been released, SobigF, Welchia, Blaster  and my
scans return nothing.

Has anyone else experienced this situation and how do I
fix it.
