Bitdefender USB Immunizer is a free tool that allows immunizing USB memory sticks to prevent malware from using them as a means of propagation. It is very easy to use, simply click on the device you want to protect.
It is worth mentioning that it is not an antivirus for USB sticksIn other words, it does not prevent viruses from being copied into them from infected computers. Just create and lock an autorun.inf file, this prevents malware from automatically spreading from memory to other computers.
Infection techniques that take advantage of AutoRun have existed for more than 10 years, in fact, large pieces of malware such as the 2009 Stuxnet worm used it. Today it remains one of the most common propagation methods, despite the fact that Microsoft has released security patches that disable Windows autorun.
USB Immunizer can also be configured to automatically protect any connected device. Another tool with similar features is USB Vaccine Pad. These are worth keeping in mind, especially if the devices are used on multiple computers in the home or shared with the office.
