.inf, the very well known virus carrier can now be immunized using Bitdefender’s USB Immunizer. This Autorun (introduced by Microsoft) has grabbed lots of hatred from security experts. Autorun.inf is a configuration file which knows what actions to perform when a new removable device is attached, but this is used by malware for spreading virus on to other computers (when the same USB is plugged into another computer).
· Using Bitdefender’s USB Immunizer you can immunize your computer and USB, thus no more virus spread. USB Immunizer actually disables the Auto run feature and deactivates the Autorun.inf file thus the malware can’t modify it.
· The only disadvantage I found is you can’t activate Autorun once you deactivate using USB Immunizer, so think twice before you take action.
· One of the best alternatives to USB Immunizer is Panda Research USB Vaccine. Even it does the same i.e. disabling Autorun but I would prefer USB Immunizer to USB Vaccine as USB Vaccine needs installation while USB Immunizer is a portable app (doesn’t need installation).
· There may be more alternatives but think twice before downloading any such apps because there are many fake apps which promise to immunize Autorun.inf file but do the reverse (checkout Lavasoft’s rogue apps page).
Another interesting thing I found is, even though I immunized my computer using USB Immunizer, USB Vaccine still shows my computer is not immunized, strange!
