I downloaded all of my antivirus programs via HTTP using a web browser. If you visit the website of an antivirus developer, there is generally a "download" link that you can click that will tell you where you can go to acquire the software.
Commercial antivirus software, however, must be purchased. There are often free trials available, however.
Rarely, you must install the antivirus software from CD or DVD. These days, however, just about every major antivirus developer has a downloadable version.
Just because there is a downloadable version however, doesn't necessarily mean there is a free version.
