Installation is simple and straightforward. The suite builds on the previous Avast Internet Security (which is now unavailable) with an automated software update tool, which can not only alert you to new updates but download and install them as well.Īnother big extra is a military-grade data shredder, which can wipe important files, documents and other personal data, and ensure there's no chance they can be recovered. Avast Premium Security 2020 is the company's premium security suite and includes an antivirus engine, firewall, browsing protection and browser cleanup tool.
