AVG has a big advantage in the free antivirus space since it owns both Avast (acquired in 2016) and its homegrown product, AVG Free. The hope is that you’ll love the free stuff so much that you’ll eventually upgrade to one of its paid products.
In the case of AVG, most people go with its Internet Security program. Priced at $70, it’s one step down from the company’s flagship product, AVG Ultimate, and lacks a number of Ultimate’s less crucial features. For example, you don’t get AVG’s PC tune up package or third-party desktop software updater. That’s hardly a loss, though, as you can find free programs to dump cached folders taking up too much space or monitor software updates. The important security features are all included in the $70 security suite, however, including antivirus, firewall, and phishing protection.
