What are Rnaapp, Msgloop, and Msg32 used for?

I'd just like to know what these files shown in task manager do. Thanks!

The fastest way to find out is to search for the file on your system and bring up properties on it, the version tab will usually give you a bit of information.

Rnaapp - its related to dialup networking, it gets loaded when you connect to the internet, and stays until you shutdown.

Msgloop may be related to your soundcard.

Msg32 - I think this is also related to sound.
