How to Circumvent/Avoid the File Type Restrictions Imposed by Google App Email/Gmail's Antivirus Scanner
Gmail is great in terms of spam filtering and phish detecting, but unfortunately, it lacks a better AntiVirus scanner.
Most popular free email services let the public know which company they use for their AntiVirus software, which is normally a popular AntiVirus company. Google doesn't even do this.
Some may wonder why I speak so negatively of Google's AntiVirus scanner. It's because certain extensions (e.g. exe, dll, ocx, com or bat) are disallowed from being sent. However, Google will waste your time and allow you to upload these files as if they were going to send them.
There are a couple ways around this:
1) The easiest method is to change the file extension. If I have a file called "install.exe" that I want to send, I can just change it to be something like "install.mp3" and Google will assume it is one of the allowed file types.
The recipient just has to change the extension back in order to use the file as intended.
2) Google scans all type of zipped files, except for .RAR. They may have changed this, but they still use RAR files to zip and give multiple files to a recipient at one time, so I suspect this may still apply.
You would then zip your files as a RAR, upload it and send. If it doesn't work, and you still would rather use a zipped format, combine the first method with this one.
3) The most effective method is to use a separate file service like Rapidshare, Megaupload, Zshare, FileServe, FileSonic, WUpload, etc., and upload your file there. You should then receive a link to the file (which may last around 30 days or so if using a free account).
Send this link in your email and your recipient will be able to retrieve your file.
NOTE: The 3rd step applies to any email service since it is not reliant upon an email service.
