I dont know what that is but Im guessing its not a bug but a virus. I suggest you use a anti virus program while downloading, wrongly named files can contain viruses/trojans and worms too and please refrain from posting titles. I suggest you scan your system with a good AV from now on or, you'll be reformatting everytime you get a virus. and becarefull what you download, pirated software contains the MOST viruses. thats why these items are free to dl from Gnutella because they are usually infested. good luck.
