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.
