a) I don't see the concern with placing .exe files onto your /own/ website. 
Presumably, if you have the files you know they are safe. The question is 
whether it's safe for you to download files from someone else's website

b) The article linked is incorrect in stating that most security software is 
incapable of scanning ADS (whilst that may have been true when the words are 
written, I've been assured by people in the AV industry that this is no 
longer the case). Every major AV program is now capable of scanning ADS in 
files as you access them. Keep your AV up-to-date.
