USB Guardian is an application that helps you prevent your computer from getting infected with viruses an worms like Conficker (aka Downandup, Downadup and Kido!). 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. You can find more details about how USB Guardian protects your PC against worms and viruses on this page. 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 into 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 dievice and blocking acces to it. In this state, USB Guardian considers the USB resource as locked.
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 autorun.info file and extracting all references to executable files which might run upon inserting the USB drive.
