You can check for corrupted system files. Open an administrator command prompt and run SFC if the above doesn't help. Click START, then type CMD in the search box, right-click CMD.EXE and click Run as administrator. Then from the command prompt type sfc /scannow.
I am running the latest XP and noticed some strange issues when I plug in any USB device. When XP locates a new device a box pops up (As it should) and asks how you want to handle the device.
As of a few weeks ago there are strange entries at the top of the list. Unreadable characters and symbols.
No virus, No Malware, No other issues. I will try to include a screen shot for you to see
I would appreciate help on fixing this problem as there are underlying errors causing this
Here is a link to the USB screen capture
