Product key recovery: I know 3 characters

Ok so I know the last three characters for my Halo product key. I tried to do it with a different product key and now it says "Your CD key is invalid" every time I log onto multiplayer. Is there a generator somewhere that can find the rest of my key?Thanks for answers.

knowing 3 characters wont work, you need them all. Also don't ask about keygens on this forum, you should know that.

Well I'm not really asking about a keygen. I want to know if there's some program on the Internet that finds the rest of my key.

only if halo is currently installed using that key. if not then you're out of luck.

not sure if it would work, try ProduKey. i use that to recover windows and MS office key on daily bases.however if you use AVG, it will detect it as a trojan (its a false positive). as long as you download it from a reliable source (like download.com), you are good.

What if I use Norton (which was on there to begin with but I never took off?

norton is unlikely to detect anything at all.

Good.

Let me rephrase, Norton is unlikely to detect anything except for it's own .exe and thinks that is infected half of the time.
