How do I remove a messed up mod?

[.JK.]

I really want to use the script, and I think that the location of the install is in a folder on the desktop, but my maps aren't there, so could the install location also be somewhere else? If the install is located elsewhere, then where should I look? I kind of think that all of the alias's are for the zombie mode, but the one for your script might be hidden in there.
