Virus scanners exit without finishing

Hi all ;D!!! I don’t know if I put this on the right board, but I’ve gone through a few AV scanners now and they all do the same thing… they start up and eventually close by themselves–no error messages, no codes, no chimes, no nothing. Something else just simply closes all my av software so that I can’t even find out what may be wrong. And this happens with all the scanners I’ve used so far. Avast, Symantec, and Pest Patrol… I’ve managed to successfully remove Pest Patrol and Avast, but I had to manually go through the registry to uninstall Symantec and that’s still being a pain. TIA.

It’s possible that you have an active virus on your computer that terminates any running AV application. Did you try to boot to safe mode and run the scan from there?
Also, it may be worth to check the applications that are started automatically when the OS boots (using a tool like HijackThis).

Thank you. That really helped. It took me a while to get safe mode going, but the scanner ran without a hitch. Thanks again.

And did it find any malware?
