With AVG, there are about 17 different suites to choose from, which may overwhelm most users. Some of these suites offer free trials, and some of them don’t. Having a variety of suites can be confusing to AVG customers as there is an overload of options to choose from. With AVG, there aren’t specific features that are labeled, as each suite just states what each suite can do. So everything mentioned from the above list is self-explanatory. AVG Internet Security and other suites are meant to prevent from any malware threats, ransomware, and virus attacks. To add extra features like customer support, anti-tracking, and unlimited VPN, they are additional purchases you will have to make. Each suite is catered to either business or personal use, and it also varies in operating systems. AVG does an okay job on laying out each suite, but it’s just too overwhelming and too customizable to choose from. Having to pay for additional features for total AVG internet security in AVG Ultimate defeats the purpose of making a suite.

Our recommendation: McAfee

With McAfee it has protection on all sorts of devices ranging from phones to even cars! It’s extensive product line-up has protected over 18.9 billion devices to this day.

Customer Service

Customer support for services that have a free version is generally a mixed bag. More often than not, you'll find it lacking. It's no exception that in this case, the situation is somewhat similar.

If you need responsive and faster customer support lines, Avast and AVG customer support is available for premium users only. In other cases, you'll be left to read FAQ sections and forums. That's the burden of free version, and neither Avast nor AVG is an outlier.

Money Back Guarantee

Both contenders provide a 30 day money back guarantee on all their paid plans.

Avast makes it surprisingly easy to claim your full refund. You fill out a form on Avast’s website containing your name, mailing address, email address, order ID, and reason for refund.

While AVG took less time to provide a refund, the entire process was not as seamless as Avast’s. We prefer a hassle-free and transparent refund process, even if it means getting a refund a few days later.

Comparing Avast With Other Options

Avast vs Avira

Avira is a decent anti-virus but pales in comparison to Avast. Both have a free version but we compared the paid versions. The biggest con about Avira is that it is an antivirus only for Windows users so if you're looking to protect multiple devices Avira is definitely not the one for you.
