To download an antivirus, all you have to do is go to the site of that antivirus and click download. For example type "Antivirus" on your browser and click search and it will give you all the antivirus out there, then from there click download.

Also you can try AVG Anti-Virus Free Edition. It is safe and unlike Norton it doesn't take up a lot of space. The link is below. I am also using it right now.
Generally speaking, all you do is click on the link on the website.
