Komt ie: een buurtgenoot staat bij mij op de stoep met de melding dat z'n PC opstart en in Windows XP terecht komt. Daarna vraagt het systeem 2x om de systeem of boot cd. Daarna kan hij niets anders meer dan hem uitzetten. Hij heeft een Hijackthis logje op diskette bij me achter gelaten:

Is het een virus of is het een ander probleem? wie weet raad?

Ik zie hier geen vreemde regels in het log.

Heeft hij al eens geprobeerd om de Windows CD te gebruiken?
