AVG is one of two antivirus products that we recommend. If you want a paid product, AVG is what we recommend. However if you want a free basic antivirus protection for home or business we recommend Avast.
For now, Avast is the least intrusive with ads to upsell you to their paid services, but barely. In most cases Avast will provide the needed protection at no cost to you.
Additionally Avast is in the process of buying AVG and it will be some time to determine which products will stay, go, or combine. Once the merger occurs and the product lines are more clear we will update this with our recommendations.
