An application that protects your PC against USB viruses and worms!

USB Guardian is an easy-to-use yet effective application that will help you protect your PC from worms like Conficker and other malware. The software allows you to safely enjoy file sharing using just an USB thumb drive for copying the files.

Movies, mp3s, documents and pictures can be copied from one computer to another without worrying of getting infected with worms and viruses trough USB drive. The interface is very clean and well organized so that one can access all functions with minimum effort.

It is possible to give a USB flash drive / USB memory stick a behaviour that is very similar to autostarting CD's and DVD's. This poses a huge security risk because you can, unintenionally run malicious software such as worms an viruses. This is where USB Guardian comes to the rescue.

The application is constantly scanning the USB port for a new removable storage device and this has led to a very small resource consumption when idle (which makes up to 99.5% from it's time). USB Guardian is able to identify which USB flash drive is inserted and it detects potentially dangerous files on the drive.

In order to reduce the risk, first step is always to minimize and control the damages and this means isolating autorun.inf file from the removable device and blocking acces to it. In this state, USB Guardian considers the USB resource as locked.

The next step is to determine which additional files might pose a threat for your system and to lock them as well. This is accomplished by parsing the file and extracting all references to executable files which might run upon inserting the USB drive.

Operating systems: Windows 2K / XP / Vista / 7

Looks like an interesting app, I'm not sure I would completely trust software to block out a threat though. Only 100% way of protection would be a writeblocker
