Spyware Scan or Antivirus Scan Causes Computer to Shut Down
Posted on 2005-04-30
I'm cleaning up a laptop with multiple viruses and spyware, but whenever I start a scan to remove either, the computer shuts down either immediately or within a few minutes. This is not a problem the owner of the computer said he was having, and I believe him because it doesn't happen during normal use of the laptop. In fact, I've now had it running for two days without it shutting down, but if I do a scan right now, it will shut down within a few minutes.
The computer does not shut down and restart, it simply clicks off and stays off until I press the power switch to turn it back on. I've set it to not restart on system errors, but that had no effect. Nothing shows up in event viewer that would give a clue as to what is causing it, in fact it does not even seem to notice the shut down. I've tried a new memory stick but it did not solve the problem. The shutdown occurs when scanning in safe mode also. I originally thought it was shutting down when scanning a particular file or folder, but that turned out not to be the case. Right now, the computer is about 90% rid of spyware and viruses, and is fairly useable, but I'd still like to know why a scan causes it to quit. I used the utility to turn off DCOM, but that didn't help. So far the different programs that cause it to shut down are: Housecall online antivirus scan, Norton Antivirus 2005, Spybot, Adaware, and Counter Spy. CWShredder says CoolWWSearch is not on the machine.
It is a Toshiba Satellite running Windows XP Home and has 256 MB RAM.
I would appreciate any advice or suggestions as to what may be causing this.
