I'm running Windows XP and I appear to have a virus that is undetectable using Windows Defender, SpyBot or Norton. Not all my programs are affected but the ones with a slide bar for scrolling up and down behave eraticly and rapidly scroll up and down by themsleves. Pressing the control key has some effect but making selections on a page is almost impossible. I've noticed when my computer shuts down or starts sometimes there's a different and longer series of beeps. I do not receive any error messages. This started around July 20, 2007.
Does anyone know the name of this virus or how to eliminate it? Cheers, Chato
