One of the major security risks is giving a USB flash drive/USB memory stick a behaviour similar to that of an autostarting CD or DVD. This may lead you to unintentionally run malicious software such as worms and viruses. This is where USB Guardian comes in to rescue you.
The application constantly scans the USB port for new removable storage devices, leading to minimal resource consumption while idle (accounting for up to 99.5% of its time). USB Guardian identifies the inserted USB flash drive and detects potentially threatening files.
The first course of action to reduce the risk is always to minimize and control damages, which is accomplished by isolating the autorun.inf file from the removable device and blocking access to it. In this state, USB Guardian locks down the USB resource. The subsequent step is to ascertain which additional files could pose a threat to your system and lockdown anything untoward.
This is executed by parsing the autorun.info file and extracting all references to executable files that may run upon inserting the USB drive. The best part is that you can enjoy the full advantages of USB Guardian for free! That's right! We're releasing this software for free so that you can safeguard your PC against any USB viruses.
