Norton 360 Deluxe is our top pick for antivirus. It's a very comprehensive security suite with a simple app that offers strong antivirus protection and protection against online threats, as well as a whole boatload of features—parental controls, storage for cloud backups, a password manager, VPN, and PC utilities. We like it for how extensive yet affordable the service is—you'll be hard-pressed to find a comparable rival.

Which antivirus should you choose? While you have many options, two stand out from the rest. Bitdefender Antivirus Plus holds perfect and near-perfect scores from three independent antivirus testing labs, with more features than some security suites. Norton AntiVirus Plus likewise offers many suite-level features, and it gets excellent scores from all five testing labs we follow. We've named these two our Editors' Choice winners for commercial antivirus, but they're not the only antivirus apps worth consideration. Read the reviews of our top-rated programs, then make your own decision.

Editors’ Note: Given that the US government has banned new sales of Kaspersky security products, we no longer recommend them.
