Notes about the MP3 file extension:



Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.

The MP3 file type is primarily associated with 'MPEG Audio Stream, Layer III'. Initial File Contents is for a file produced by the Xing Encoder. Note: This file type can become infected and should be carefully scanned if someone sends you a file with this extension. The Macintosh type is: MPG3 Starting in October 2007 MP3 files started being used to carry spam messages starting with a stock pump and dump scheme. Expect more as some filters don't block MP3 files which are widely shared. In early 2008 infected files with the MP3 extension started to spread on Symbian OS devices (e.g., Nokia 6600, 6630, 6680 and other phones). Since the Symbian OS recognizes file formats and does not depend on the extension these renamed SIS installation files looked like data files. If a mobile device asks about an install when attempting to open an MP3 or other data file then beware as it's likely malware trying to infect the device.
