Having been on the net since 1996, I have found the perfect solution to spam and even e-mail viruses.
Never use the e-mail address given to you by your ISP. You never even have to use outlook which is a target for e-mail viruses.
Get a free e-mail account at yahoo.com or hotmail.com. When you start getting spam there, just get another one, inform your friends of your new address and abandon the old one. It is that simple.
When I am showing someone who is new to the internet how to use e-mail I set up an e-mail account for them at Yahoo.com and bypass all of the learning involved in using their own e-mail client.
