I'm an average user (mostly), so forgive me when I don't know some of the terms.
Using XP, with McAfee SiteAdvisor, Comodo Firewall, Spyware Doctor, Malwarebytes, McAfee scanner 8.7i and Super Antispyware (all of them the free editions).
My mouse pointer occasionally goes crazy. It's happened four times, twice yesterday and twice today so far. It would jerk to the left every time I tried to move it around, so it made clicking anything impossible. And when I left the mouse alone the arrow would (slowly) keep moving to the upper left . I couldn't close windows because it's the same with the touchpad, so I had to pull the plug and remove the battery to reboot the laptop.
I noticed, though, that the last two times the problem happened, it was because I left the laptop alone long enough for the screensaver to appear. I'm in the middle of a virus scan now, but this is my third attempt. I left my laptop alone the first two times, and found out the mouse poointer was going crazy again when I went to check on the scan progress. Now I'm playing a movie file while waiting for the scan to finish so the screensaver won't appear.
Anyone have any idea what's going on?
