CD tray open and shut case.

Last night the CD tray started to open and shut of its own accord,did some checking on works computer today, seem like this is a virus which was active around 2008,done a scan with Malwarebytes and caught the bugger and put it to rest. Problem solved.

Get yourself a decent AV and run it just to be safe, sounds like something script kiddies like to do for fun.
Can recommend KAV, NOD or Endpoint.
