I have an hp pavilion a250n running microsoft windows xp. The problem started when I went to open my portable media player, usually found in the control panel, to put music on my mp3 player. The device simply wasn't there! My antivirus (wildblue security center; f-secure)) scanner recently found a virus which couldn't be deleted. Could this have something to do with the program's disappearance? I just can't figure this out. I thought the media device was integral to the computer's hardware, and to have it just disappear is a mystery. I have looked in the recycle bin and in every list of programs I can think of. Any ideas?
