Is there any official explanation for why MSN Messenger deletes mp3s if you get sent them and try to open them by clicking the link it gives you (the alternative being to navigate to your downloaded files folder)? It says it's potentially harmful and just goes ahead and deletes it, no asking the user, it just does what it feels like. Now I could understand it for executable files, but why mp3s? Executable files, by the way, are not deleted, you just get the potentially harmful warning.
I wonder why I'm gradually not using any MS software?
