How can you get virus protection free?

You can download several different virus programs off the internet. I use AVG Free edition. I have used it for over a year now with no problems. I downloaded it from filehippo.com. I will include the link to their virus download page below. They have several options.

Windows XP has a firewall built in. Go to your start bar, control panel, and click on security center. The option to turn it on will be there.

Answer:

I used almost a year Comodo Internet Security and I was satisfied with it. It is free and includes a firewall, an antivirus scanner and a malware detection engine.
