Opinions, please: What's the best spam filter software?

Question

Mine catches about 90% of the spam so I'm not complaining; still, if there's something better I would at least consider it. All input is appreciated.

Answer 1

I used to have McAfee, but dropped it because it was slowing my computer down.

my cable network has Spam guard, also Mozzilla Firefox comes with them.

the only Spam I get is what I signed up for, big mistake, but as soon as I see who it is from, I delete it without opening it.

however my wife has the same thing on her computer, and she get a lot of it, from a couple of websites that she signed up with.

the best Spam guard is to be careful who you give your address to.
