Ninja Pendisk

Ninja Pendisk is a software solution designed to join the fight against viruses and other malicious threats that attempt to infect USB flash drives. The program tries to secure devices and remove existing infections on the fly.
In case you are not interested in manually configuring all the settings of such applications, you will definitely like Ninja Pendisk because it does what it's supposed to without requiring any user interaction.
For example, the tool will quietly sit in the System Tray and monitor the activity and it will come into play every time you plug an USB pen drive into your computer. Plus, if you continue to use it with the default settings, Ninja Pendisk will also scan the device and immunize it automatically, without even bothering the user at all.
This software was mainly designed to block the infection spreading via the autorun.inf file. In order to do so, it will create a folder called autorun.inf on every single USB flash drive it protects, with special commands to block the virus.
In case you want to tinker with the app, you can easily do that by right clicking its System Tray icon and disabling the automatic clean option.
The interface is minimal, but Ninja Pendisk works so fast that you barely get to see it. The time in which the program does its job depends on the size of the USB flash drive and the amount of data stored on it, but, during our tests, the tools proved to be very fast all the time.
All things considered, the software will prove its worth if you give it a try and, overall, Ninja Pendisk is a good choice for protecting USB pen drives and getting rid of malicious code that might infect them.
