a free fire wall, which I also have and mine's also been going crazy, especially for the port 137, at about 70 - 76% of the attacks.

see zone alarm here (there's a free version and a pay version (zone alarm pro), I've been using free version fine).

I would suggest adding "spyblocker" and "script Defender" to the mix along with zonealarm.
