What are the best antivirus software for flash drives?

Bitdefender USB Immunizer (recommended)

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 cyber criminals.

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

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.

Panda USB Vaccine (suggested)

The Panda USB vaccine is a free utility that disables the Autorun feature from USB drives, preventing malware from infecting your PC.

When this software is applied on the USB drive, it will permanently block the autorun.inf file and it will prevent it from being read, created, deleted and modified.

In this manner, Windows won’t be able to automatically execute any malicious file that might be stored on the flash drive.

You can then use your USB flash drive in a normal way to copy, move or delete files.

The software works great on FAT and FAT32 USB drives. As a quick reminder, the USB drives that have already been vaccinated can only be reversed to a previous state through formatting. Users can also operate the software via the command line.

We also recommend downloading Panda antivirus (50% off) which will double your USB-health security.
