What’s the best antivirus software for USB flash drives?

Bitdefender USB Immunizer (recommended)

get Bitdefender USB Immunizer

Autorun-based malware is one of the world’s most vicious e-threats. Introduced back in the Windows XP era, the Autorun feature has rapidly become the main infection tool for many cybercriminals.

The USB Immunizer software is Bitdefender’s response to this enormous and steadily growing problem. The software disables autorun-related threats before they can access your PC.

Once the program is installed, it will regularly check for newly inserted USB storage devices, immunizing them on the spot.

If you plug in an infected USB drive, your computer will not auto-execute the malware code stored on it. The Computer Immunization setting disables the registry entry related to Autorun.

In this manner, a removable storage device (except for CD & DVD ROM media) won’t be able to execute any malware upon mounting.

It also immunizes each system partition with a specially-crafted autorun.inf file.

The USB immunizer is available in English, Spanish, Portuguese, Arabic, Thai, Vietnamese, Polish, Farsi, German, French, and Romanian.

The software reads the current location of the user in the Region and Language settings and automatically loads the appropriate language file.

Do note that the Bitdefender antivirus for flash drives is not a standalone program. It comes incorporated in the complete antivirus package.



Bitdefender is a big name in the antivirus business, so it’s the best choice for protecting USB flash drives.
