Hi Susuan It is www.spamfighter.com for privateusers.I find it great. If you install it make sure to check it periodically because sometimes a message that you do want (not junk) might go into it.
-- I am using the free version of SPAMfighter for private users. It has removed 454 spam emails to date. Paying users do not have this message in their emails. Get the free SPAMfighter here: http://www.spamfighter.com/len
