i heard of that one
yes, that it could also be...
if the machine wont shutdown it could be that particular virus, or one like it...
but even if you dont want to install the utilities i added, you could try typing the command i mentioned first into the run bar.
that always works for me.
and i saw in another post that this isnt the only problem you are having, so i would second the motion that it is a virus. you might go to
www.trendmicro.com and do the free virus scan...
well, i am about out of ideas..
