With Protect My Disk, you may protect your computer with an antivirus program, but what do you do when you have to plug your USB into another computer? Your USB flash drive is exposed. Protect My Disk is a simple program that helps you protect your USB flash drive against autorun viruses. No extra space used and no programs installed on your USB flash drive. The program analyzes your drive, cleans the known viruses (if any) and then creates two special folders that prevent Windows to copy autorun files and other viruses on your USB flash drive.
