IRClean is a 100% free, standalone, Compact, and easy-to-use yet very powerful anti-Worm system designed to specifically combat worms that target or use iRC chat networks to propagate. It has been released into the public domain for free to help stem the growing tide of IRC-propagating worms.
IRClean is very easy to use. When run, it will prompt you for a location to scan. You can scan an entire drive such as C:/ or a directory such as C:/Mirc. Scanning can be stopped in mid-scan at any moment by pressing the Stop button.
If IRClean has detected any files that have the characteristics of IRC-propagating worms, you will be alerted. Test worm included. Due to controlled design, it cannot spread or cause damage (so it is not a true worm), but is an actual real sample and demonstrates at it's most simplest how a worm can infect mIRC. TestWorm will backup your script.ini file to script.bak.
