Well Lapsy I hate to tell you this but this is Old news. The MAFIAA aka the (RIAA & MPAA) actually hire organizations to Flood the Network with Fake Files, Viruses, Worms, and Spam in an Attempt to discourage the use of P2P. I would suggest Downloading ONLY Audio, Video, and Books from the Gnutella Network. If you are interested in Games or Programs DON'T use this Network. Here is a list of File Extensions to Filter OUT to help you stay semi safe amd other suggestions and Info.
Try these suggestions.
What I have done that works really well is to go to Tools > Options > Filter > Keywords and then add these file extensions: .wma, .exe, .rar, .html, .com, .zip, .mov. Be sure to tick apply and O.K. There are a ton of fake and corrupt files with these extensions. I will only download mp3 files that are larger than 2000kb - 3000kb. Also make sure thay have a bitrate.
