Most likely you have picked up a virus on you PC. I remember reading a How To on this before, together with advice about which program is currently the best to use.
If you don't have anti-virus software then get it, or otherwise make sure what you have is up to date then run a full check-up routine.
If that doesn't find the little sucker then you may need one of the specialist software debuggers - but they are free.
