Sistray .exe stub

Hi,

I think that my notebook has a virus. Windows Task Manager shows a new program, if I close it after some minutes it restarts with a new name, in the description field I read "Systray .exe stub".

EDIT: problem solved installing Microsoft Security Essentials (Avast didn't solved it).
