USB Flash drive has a worm. How do I remove it?

Press [Windows] + [R].

 Type CMD and then click OK.

At the prompt, type I: (if I is the drive you are looking for) and press Enter.

Then type DIR/AH to list all the hidden files. If you find the file AUTORUN.INF and VirusRemoval. vbs, type ATTRIB -r -s -h . to unhide and remove the read-only permission from it. 
Then, delete the file using DEL command (eg. DEL AUTORUN.INF) or using Windows Explorer. RECYCLER is another folder that is home to some other worms.
