McAfee

McAfee is great if you are looking for entry-level security to protect your system from viruses. McAfee is a premium antivirus software that offers installation on up to 10 devices irrespective of whether you're using Windows, macOS, iOS, or Android.

The reason why McAfee is one of the top 5 best antivirus in 2021 is, it comes with a file shredder, a bidirectional firewall.

Plus, McAfee Internet Security has one of the best password managers in the enterprise, but parental controls require you to choose McAfee Total Protection or McAfee LiveSafe, which comes pre-installed on many new computers.
