Hi. A couple of days ago my mouse started going crazy. It will work fine for a while and then it will go mad, jumping around the screen, closing programs, trying to open new programs, on several occassions it has actually managed to shut the computer down.
I have scanned my computer with the latest version of my virus software and it found nothing. Tried scanning it with symantec's online scanner and it found nothing!
download spybot seach and destroy or another trojan/adware program (preferably more than one as they work in different ways)you may have a back door to your system being utilised by someone(these are not always picked up by your virus scanner)
if your mouse seems to be following a logical course then it stands to reason that someone is directing it
if not following any set pattern it may just be faulty drivers (particularly if you have a wireless mouse or a optic mouse)for your mouse try plugging in a bog standard old mouse and see if the problem goes away regards
when did you last actually take the ball out of it and clean inside it?? as even a humble mouse needs cleaning ..( yes..serious!!)( the mouse trap gets set later when it refuses to stop jumping aound!)
