Getting AVG Free
If you want to get a good antivirus program without spending a dime, then you should really look into getting AVG Free. It's a great antivirus software suite. I've already covered why AVG Free should be enough to protect your computer, so now let's take a look at how you can get it.
This is actually pretty easy. Any time that you try to download a program, you should just go straight to the source. The website is http://free.avg.com/us-en/homepage. Just go here. You can read a few things on the website to learn more about the product if you want. For our purposes, just click on the button that says "Get Free Antivirus."
They'll try to give you the upsell for the paid versions. These have some decent features, but the average user should be fine with the free antivirus version. Click on the free version to download it. You'll have to click again to go to their secure link at Download.com. Just do one more click to download the latest version. It should be a very small download, so it will only take a minute.
Double click on the installer file to fire it up. You will need a valid Internet connection for this to work. The downloaded file is just the starter. It will download the rest during the installation. Click through and pick the basic protection package once again. Then go grab a sandwich while all the files download and install. You can entertain yourself by watching the little "remaining time" thing jump around from a year to 2 minutes.
Once it's all done, you can just click through the rest to finish the installation. It should be fairly self explanatory.
