There's another way besides using 3rd party. Have been using for the past 1.5years for PC malware troubleshooting and not an "infection" on my thumb-drive (touchwood).


1. Browse to your removable drive
2. Create a new folder
3. Rename the folder as autorun.inf
4. Now, open the command prompt [how?]
5. In command prompt, change to your drives directory. For example, if your flash drive is labelled I: in My Computer, then type in the command prompt I: and press enter
6. Then type attrib +s +r +h autorun.inf

The last command is to protect and hide your fake autorun.inf and make sure that the file is irreplaceable by the malicious autorun.inf file. Now, next time you plug-in your flash drives on an infected computer, the malicious autorun.inf cannot be copied into your flash drives, thus saving your drives from being a virus carrier afterward. The virus itself, however, might be copied into the drive, but let your anti-virus take care of that.
