USB vaccine, preventing your autorun.inf to be modified

Posted by Hari Saryono on 14 March 2009

Do you know that almost all the virus infection began from USB flash disk?. Yes, new virus model now progressively use this feature. This is of course very effective, because everytime the flash disk connected to the computer, virus program work automatically.

To prevent this risk, you can use Panda USB Vaccine. It is a free utility from Panda Security Research which helps prevent malware infections due to the autorun feature of Windows Operating Systems. Once executed the user can choose two types of vaccinations: Computer Vaccination or USB Drive Vaccination. USB Vaccine allows users to vaccinate their PCs in order to disable autorun completely so that no program from any USB/CD/DVD drive (regardless of whether they have been previously vaccinated or not) can auto-execute. This is a really helpful feature as there is no user friendly and easy way of completely disabling autorun on a Windows PC. Panda USB Vaccine can be used on individual USB drives to disable its autorun.inf file in order to prevent malware infections from spreading automatically.

When applied on a USB drive, the vaccine permanently blocks an innocuous autorun.inf file, preventing it from being read, created, deleted or modified. Once applied it effectively disables Windows from automatically executing any malicious file that might be stored in that particular USB drive. The drive can otherwise be used normally and files (even malware) copied to/from it, but they will be prevented from opening automatically. Panda USB Vaccine currently only works on FAT & FAT32 USB drives.

BEWARE : Also keep in mind that USB drives that have been vaccinated cannot be reversed, mean you can’t delete or modify your autorun.inf file until you format it
