There were overlapping protection software and we have to go find it. I think the combo was Zone Alarm and Mcafee but you didn't note ZA.
I have an HP with 32 bit Vista, 4 GB Ram and 250GB Hard Drive. everytime I restart the Computer I have 79.2 GB free in my hard drive and after 2-3 hours without copying anything, it becomes full and everything including my Mccafe stopes running.
and when I restart it comes back to 79 GB and the hard drive works vigorously to fill it up again.
is it a virus? something wrong with the hard drive, or some update from windows has made this?
