I've run ad-aware. I've run AVG. These programs claim my system is clean. I use the mozilla browser, I have my Zone Alarm firewall set to stealth and I have pop-up stopper engaged. In the middle of browsing or posting more and more frequently my mouse pointer goes nuts and a bunch of stuff opens and closes rapidly and I can't stop it it just does that and I have to wait it out. Soon as it stops I reopen whatever programs it closed on me but I know it's gonna happen again. Anybody have any idea what is happening? Is it just a flaky mouse maybe? Is someone hacking in to my puter despite my firewall? Is there maybe a serious problem with my puter hardware innards? Mostly it's annoying but if my puter is about to blow up I wanna know so I can get it fixed. Thanks.
