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 click 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.

Also use the Keyword Filter to filter out select words that may be a concern. (same filter as the extensions above)

Just by adding the above file extensions to the Keyword Filter will make a world of difference. If you find that you Don't want to filter some of them, then remove them from the filter. Hope this helps.
