Worm removal from USB

October 10, 2010 at 16:15:59
Specs: Windows 7
Plugged a USB drive into my computer. Microsoft Security essentials detected this worm. "Worm:Win32/autorun.UI!inf"

It claims to have removed it, and all files appear fine on my computer. However, everytime the USB is plugged in, security finds the same worm to remove... again.

The USB now has various files on it which were not placed there by me, all of which are shorcuts and not the actualy files. Some of the original files have been converted into shortcuts as well.

This all started when trying to transfer photos for classmates from one computer to the next. 4 USB drives have now been effected in the exact same way.

are there files on the drive you can't lose??
if not , create a bootable cd from this:

and use it to format (wipe) the USB drive. Be carefull not to format your computers HD!

I stopped worrying about the other drives and have just been focusing on one. Its been re-formatted twice now, all done through the command dialog.

I can delete the autorun.inf file, but once I unplug the drive it returns at the next plug in.

I've tried about 8 times now to delete it and re-format the disk... nothings working. Its a persistant little worm...

if you format it using my suggested method and the problem persist, then the usb drive is not the source.
