Ya got that right!! Last Spring, my son's wife downloaded some Kazaa crap and then the klez virus got to me through them. It destroyed my computer. I actually bought a new comp because it would be so costly to have the '98 purged of it. He did too.
No more Kazaa at THIER house!
One of the nastiest, IMHO is when a program is inserted that tells the computer when it is ordered to start up "to shut down." Basically shut down, means shut down and start up means shut down.
This virus can sit in a computer for months. When a person restarts his computer as directed for a legitimate program to be effective the computer won't reboot. Also a person shuts down and goes on vacation and comes home and can't restart his computer.
Usually hardware gets the blame first, and it takes awhile to know what happened. I would imagine a few good computers got junked because of the malicious program. -Tom
