You see it everywhere, every file that gets posted has his first 20 comments : virus scan plz !!!
So my idea is to punish those who are to lazy to just scan or even take a moment to look what for sort file type it is (saw .au3 files getting posts as VIRUS VIRUS... It is the freaking source...) or you can give people something extra when they scan a program (rep, ability,...)
Hopefully some people will support this idea.
