Gmail is very straight forward in their file uploading policy, they do not allow various file extensions, and a couple of those are the .exe, .zip and .rar file extensions.
When you try to upload a .rar file which contains an executable or any other type of extension that is often used by malicious applications, the upload will be halted, and you will get a message from Google stating that your file has not been uploaded as it might be malicious.
I tried to encrypt and password protect the .rar file with its own password wizard and encryption module (for the filenames), and it was still detected by Gmail.
So I tried the same on Facebook, and guess what, it worked like a charm.
