In my status window, I keep getting

oftpportupdate Unknown command

everytime. >_< I know it's an erroneus script, but I can't find it anywhere! >_<

However, I think I know what program caused it, but then I still don't know how to remove that script, because I already removed that program (it was a program that checks mIRC for worms)

Any suggestions how to remove the damned thing? It keeps appearing every two minutes.
