Free Anti Spam Software

Several months ago I started getting Nigerian scam emails e.g. I’m a prince from oogaboogastan and I need to send my 10 million dollars in diamonds to a trusted source. Please contact me with checking account number, social security number and a small deposit…. Who the heck falls for this? Anyhow… I keep marking them as spam but they keep coming from a different email each time. I’m about ready to switch my email to google just to stop the constant barrage of crap. Any way to make it stop?

When accessing via Outlook Express?
Appreciate any help

Thanks

How to stop spam from any_email@exact_spamdomain.com?

I receive a lot of emails from site with the same domain name. Any ideas how to stop that spam if I have Yahoo email? What settings should I change in my Yahoo! mailbox?
Thank you.

Every time I try to logon to Yahoo a keylogger always tries to prevent me from reading my email. Are there any software programs Yahoo can suggest to counter-attack keylogging software? Does Yahoo have any software programs which prevent about:blank from sending blank emails to a user’s email box and from sending blank characters inside the email? Does anyone know of any safe software programs that can work with spam protection?
