Clean Autorun.inf Viruses from USB drives
Most of the computers are infected by USB or Flash Drives containing autorun.inf viruses. Although you can protect your computer by turning off the autorun feature, more permanent solution would be to install Net Studio USB FireWall. It is a freeware that sits on your computer system tray and monitors all the usb devices for autorun files.
Once the autorun files are connected, it’ll delete the files and associated applications (mostly viruses). It works in the background and is very light on system resources. However, being a preventive measure, it cannot clean the system if it is already infected.
The software is available for free from net-studio.org
