I want to publish my program in internet, so anyone can download it freely. It is closed-source. As far as i know i have to use some license, copyright isn't enough. Is that true? If so, what license? My program falls under the 'proprietary software' category obviosly, so...Can anyone give me some advice? Do i have to use some license or just use copyright notice in some places in the application?

Evil closed source bugger.

The only real concern with the license is to say "this is mine" and "use at your own risk"; the former is implied, the latter may need to be explicit.

This standard bit of verbiage you'll find in many open source licenses can still apply to you:

in my personal projects I put:

Please do not steal my stuff, its not hard to put a line of text saying "Thanks to Ryan ********" (now all you have to do is copy paste that!). I hope you enjoy my product but be warned: By putting this software on your computer you use it at your own risk, and to whatever my code feels like doing.
