Ok it looks like its available for “limited downloads”. While I am not sure what that means, if your looking to try a different Free Antivirus and Antimalware solution, then it may be worth trying MSE. You can download it from:

P.S. I have it running and it seems very lightweight and immediately detected my IPScanner app on my jumpdrive. I told MSE to ignore it, but I was impressed that it detected something no other product has called out.
