I don't know if I can help, as I'm not any sort of techie at the
operating system level.
My problem - as you can see from my post - was cured by removing the
Ad-aware program. I'm assuming it was caused by a clash of spyware
check programs with/without the operating system, since removing one
caused the problem to disappear.
If you look at the thread of others with the same problem, they seem to
have it from two firewalls clashing, or two virus checking programs etc.
Maybe your child started a second virus check program or firewall
program?
