i have a bit of a strange problem. every 15 minutes on the dot a little box opens up on the open program bar at the bottom with no name. although it doesnt generally interefere with programs it does with games and shuts them down. i have scanned my pc with a full norton scan, adaware scan and spybot scan and they show up nothing. i have checked through task manager for anything odd but nothing dodgy comes up. can anybody help?
