I am not sure if others will, but I am reluctant to check that site, for 2 reasons;
1] mIRC is now a haven for script kiddies who think it is fun to write script that can do untold damage to someone's system. Add to that the spyware writers who use mIRC to distribute their spyware, and you have a hotbed of potentially damaging malware there.
2] That "KiLL-ScRipT" scares me to death. Who knows what it is going to kill.
I downloaded this script: http://www.download.com/KiLL-ScRipT/3000-2150_4-10442469.html and I ran the .exe put it on my c drive, but now I don't know what to do with it. If someone could help it would be great!
