What is a good firewall protection that's free??I'm trying to avoid getting the april fools virus?

The news tonight said that the conflicker virus (April fool's day) is very real. Make sure you computer stays updated with automatic updates and make sure that your virus protection is current. Using your virus protection, run a scan. I think you will be okay as long as everything is current. Please read my post over in the seniors section. (communities and groups) It tells more about what you need to be looking for, what e mails to not open up, etc.

Just be aware that the virus is a nasty one, be careful, and you should be okay.
Your last question...the virus is spread through many social networking sites, including this we are on and facebook and others.
