Features and How to Use Panda USB Vaccine (5 out of 5)

Default Setup

Panda USB Vaccine is very simple to use: Simply vaccinate your PC or USB drive and you’re done!

The only feature of Panda USB Vaccine is to vaccinate. Two methods to vaccinate are offered: PC vaccination or USB drive vaccination. When you allow the utility to vaccinate your PC or USB drive, it will disable autorun.inf so nothing or no one can modify, delete, create or read the autorun.inf file found in the media via USB drive.

You can configure Panda USB Vaccine to automatically vaccinate any new drive. Using the command

Note: If you have a USB drive that does not have autorun.inf file, it is quite safe to vaccinate it. However, if there’s autorun.inf file in the USB drive, you need to remember that you cannot use autorun feature.

Why disable Autorun?

Microsoft has shown a graph on the number of infections caused by the feature in Windows, Autorun. They decided to disable Autorun feature in Windows to prevent further growth of the infection that will spread using the autorun feature. However, it will not prevent autorun in running if you inserted a removable drive e.g. CD or DVD. With Panda USB Vaccine, vaccinating the computer will disable autorun feature for inserted CD or DVD drive. The screenshot in the left shows autorun is enabled when I did not vaccinate the computer in Vista with SP2 while the image at the right will not show the option to autorun simple because Panda USB Vaccine has vaccinated my computer so if I’m not sure whether the DVD is infected or not, I’ll be safe since Panda USB Vaccine prevented autorun to run.
