Knights of The Farce

Anyone ever use kotf or knights of the force? Ive heard many things about it like it contains viruses. But a lot of people also say they never got viruses and the game runs fine. while others say its slow.
Anyone have experience with the game? I want your opinions. Here are the trailers. they are always fun to watch. They add a lot more to JKA but its a very, very large file for a mod.
