Infected by what?

[HavanaBanana]

Some activity on internetconnection (packets sent and received) before I open any programs.

Mousepointer is moving around, typically to a corner, and mostly start corner. (whilst I am playing poker or browsing or anything else.)

Have used Adaware, Norton, Spybot and Blacklight.
No help.

Anyone got some good advice?

Thanks,
