I have an old computer, with Windows XP, sp3. Let me say right off I am not very computer literate, although I do spend a lot of time on it. Recently, my computer has taken on its own personality...all of a sudden, the cursor, on its own volition, opens every tab it crosses, resulting in stuff popping up on the screen I never dreamed of. I can eventually get it all off, but sometimes I have to reboot. I have run AVG and Superantispyware, and nothing, not even a little bug. In addition, sometimes it is sloooooow! Any thoughts? Yeah, I know, it's time for a new computer, although I am comfortable with this one when it works correctly.
Thanks in advance,
