Javier,
Thank you for pointing this out, I guess I should have included another
disclaimer as to what I consider to be free - though it's hard to believe
that the results of a scan are not re-distributable.
By "free" I meant free for end-user who's not a security professional -
(or somebody who's doing such scanning for living - they probably wouldn't
use MBSA anyway, or would they ?) nor is going to re-sell the code or
its derivatives; that is "free" for a guy like myself, which is a bit
self-centric, but I did talked about it in the beginning of my first message.
