Well, since last week, my USB ports have been disconnecting and connecting all the time. This wasn't much of a problem so I disregarded it. However, today, sometimes my mouse gets disconnected for no appearant reason and on the Windows bar it says "Device Malfunction". I'm like WTF? So I mess around with it, vacuuming the dust etc. However the problem did not go away. Now when I tried to connect several USB drives in my computer it all says "Device Malfunction". I tried on my Dad's laptop and it worked fine. Is this a virus/malware/spyware? I have AVG Internet Security 9.0 and the scans showed nothing. Running XP professional. Thanks.
