Best anti-crap software

If anyone has any suggestions on software that I should check out or review please post a comment.  Here is the stuff that I currently use and will review.


SpyWare and MalWare: adAware
PopUps: Alexa ToolBar
Spam: SpamAssassin (server side)
AntiVirus: None


If an all in one solution exists I would love to hear it.  Also let me know if you would like reviews of client side firewall software (like Black Ice).
