Many fake MP3 files contain an infection such as the Downloader-UA.h Trojan.
A countless number of computer users have downloaded MP3 or various video files from popular P2P networks only to find out that the file downloaded is not a legitimate music or video file. Many times we search P2P (peer 2 peer) networks or client applications such as limewire or bit-torrent sites in an attempt to find a certain shared media file or files. Whether it be a MP3, WMA or AVI file, we are finding that a large number of downloads are infected with a form of malware that may install dangerous software or files onto your computer.
How do you know if a MP3 file is infected?
Have you ever downloaded an MP3 file that was titled just like it should be but when you attempted to open the file you were prompted with a message stating that the format does not match the extension of the file you are attempting to open, open anyway? A number of times this is a clear sign that the file you just downloaded is not what you are looking for. The file is either corrupted or in most cases some form of a Trojan, malware, spyware or virus infection. When you proceed to select "yes" this gives the file permission to install infected files or malicious applications onto your computer.
