any one know MS outlook?

I recently changed to Earthlink and now i am getting all sorts of garbage on my outlook. It is my family only email... for years. Only 4 people have this email addy, Now i am getting weird stuff.
Help if you can? How can i block this?

I would check with Earthlink to see what kind of spam blockers they have. I looked around their site and came up with spamblocker.

Also, you may have the people who have your email address check their computers for viruses. I started getting all sorts of junk from weird and old email addresses and found that my in-laws computer was just full of viruses.
