Question

I want to have a simple application that is in .exe (executable) format hosted on a secure domain that, on my website, a user can click to download and run. However, I'm aware that many annoying viruses are in the form of a harmless-looking executable, so I naturally would want to also put, as a small notice for that download, something like "Not a virus - trust me at your own will". But this leads me to a certain concern.

How, if possible, could that executable become infected? Is what I'm thinking of doing stupid? If so, what is a better alternative? What precautions should I take?

The last thing I want is for a file of mine to become infectiously corrupted and to have the possibility of it messing with others (though Linux users are more or less safe).

Explanation / Answer

If your server is properly secured and you don't have an interactive content, it is unlikely that an attacker will be able to modify your file on your server, however unless you use an encrypted connection to your visitors, then it is theoretically possible for someone to get in between you and the visitor and replace your server all together.

Either way, simply saying "this is safe" is pointless. Either people will accept the risk or they won't. What you may want to consider doing is placing the file on a software sharing site like CNet's Download.com. They automatically virus scan files that are submitted and so people are more likely to trust it if a third party has said it is safe.
