HELP!!

Ok, I've never posted a problem before, but this one is stumping even my IT sources. I remote into my office w/logmein. Starting Friday, it appeared that another user was also remoted in until the movements became random. The "ghost" cursor switches minimized tabs, launches start up and attempts to other programs. While in incredimail, attempts to add background. I've run spybot, removed some minor things, ccleaner, hijackthis, and AVG and the gremlin continues to torment me. If anyone has any idea what this is, I sure would appreciate any feedback. Hari kari's looking tempting right now. Ugh.

Thanks for the input Frozenlead. I removed about 400 items, but nothing was malicious. My regular IT Guy came and and he believed it was a hair on the mouse optic. I find it quite strange that would cause random launching, but it has gone away.
