Editorial review


Pedro Castro Senior editor

This review applies to version 2.8. The latest version of this software will soon be reviewed by our informers.

As suggested by its name, USB Guardian can protect your computer from malware, including worms and viruses that can use your USB memory device for transmission.
This AV program can be set to start along Windows and remain hidden in the System Tray to monitor infections running from connected USB devices.

The program allows you to disable the autorun feature, thus protecting your system from ill-intentioned programs that can start automatically after a USB device has been plugged into your PC. However, you can exclude CD-ROM autorun to keep it functional.

The program works by scanning the USB gadget and detecting potentially dangerous applications, which are immediately locked. Then, you can decide to delete some or all of them. Similarly, you can unlock given programs when you are sure they are not harmful.

Unfortunately, the application does not have an attractive interface. However, it is very easy to use. Most of the times it will work automatically independently of your actions. Moreover, you can access its main window from the System Tray. It is a pity that this program’s installer practically forces the user to install a browser toolbar and change their default search engine and home page.


  • It is very easy to use.
  • It can block USB threats.


  • It has an unattractive interface.
  • The installer practically forces the user to install a browser toolbar and change their default search engine and home page.

Publisher's description

USB Guardian is a special software application which prevents your computer to get infected with nasty viruses an worms like Conficker (aka Downandup, Downadup and Kido!) which have spread already to over 9 milion computers. USB Guardian allows you to safely enjoy file sharing using just an USB thumbdrive 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.

USB thumbdrives have become a comodity and this fact is actively being exploited by criminals who have developed special viruses and worms which infect USB storage devices like thumbdrives, cameras and even mobile phones.
The interface is very clean and well organized so that one can access all functions with minimum effort.
