"whats is a good site to get a free antivirus protection for my laptop..." besides "Norton"
Microsoft Security Essentials is a good one.
A good site where you can get a free antivirus protection is download.cnet.com. On this site, you will get the ad-aware free antivirus program that requires one-time activation through email. You can also download avast software on the same website.
AVG is pretty good.
