No autorun is a tool which stops the virus present in the USB disk/flash drive from auto-running. This tool prevents the transfer of malicious programs through USB devices after the initiation of autorun. The file is of just merely 42.32 kilobytes. This is a free tool so no payment is required for its’ use. It runs efficiently on Windows XP/Vista/7 operating systems.

This application informs the user about whether a USB drive is infected or not. When any USB drive (May it be a flash drive or disk drive) is inserted then this tool instantaneously locks the file named autorun.inf which in turn freezes all the viruses and suspicious files related to autorun. There are a bunch of tools bundled to look out for the infected files, the suspicious files. These tools are the ones responsible for the removal of these malicious elements.

No autorun silently runs in the background and is present in the system tray and comes into existence when a new external drive is connected. There is a configuration screen present for the user where he/she can easily disable the autorun while keeping the autorun for CD-ROM active. There is an option available for scanning of all drives at the start only. Moreover the consumption of No Autorun is minimum so the system continues to work at its’ normal rate.
