Best you tell us what you actually tried to download. Obviously the word you used in your original post triggers LimWire forums bad word filter.
Try again - this time use a different term to describe what you are trying to download. If you are getting files that you did not specify it probaby means your computer is infected with a virus or trojan which downloads what it wants not what you want.
Run a reputable virus scanner over your whole computer as it looks a lot like you have been infected by a virus.
