How to Send Exe rar Files through Gmail and Yahoo mails?

I had tried several times to send .exe files through mail but I will be getting the error message or even if I download any of the .exe rar files after extracting you can’t see any exe files instead the format will be changed to images. Another easy way is to share .exe files we do is that we will upload to any free file hosting sites like rapidshare, mediafire, megaupload etc… and send the link through mail. The simplest and easiest trick without logging in any of the file hosting sites we can upload and share the .exe files with your friends. All you need is a Microsoft Office to do this trick.
