Something (Trojan?) Controls Mouse

[PapaBear]

Some program on my computer takes over the mouse, takes it to the edges of
the screen and clicks it madly, tiling windows, opening programs etc. I run
W2K Pro and I have installed both ZoneAlarm and Norton Internet Security
after the problem began - so now the program must reside on my local drive.
To stop the mouse mischief, I do a Ctrl-Alt-Del which most often, but not
always stops the mouse. I see no unusual processes running, so the mouse
process must be hiding somehow. I checked registry and cannot see any
unusual programs under RunOnce or Run. I also have Norton Antivirus with up
to date virus definitions and nothing is detected.
Has anybody seen something similar before? I would like to get rid of the
problem without having to reformat/reinstall.
Thank you for your advice.

What kind of mouse? - that is, USB or serial? Is it wireless (in this
case, have you checked the batteries? or checked for sources of electrical
interference?)

Plain vanilla Microsoft PS2 mouse. Never had any problems with it before.
Thanks.

Changed mouse, so far so good.
I will use the software tools just to be sure.
Thanks very much.

A friend of mine had the same problem. Turned out he had a worm virus.

Hi,

I had this problem several years ago. I was convinced there was a
trojan on my system but my AV software didn't find a thing. I even
called in a techie. We were both stumped. I was about to reformat my
hard disk when I began to wonder.... The answer was a simple one: I
changed my mouse! If you haven't tried this already, give it a go. I
hope it solves your problem as quickly as it did mine. Good luck!
