Everyone knows how good NOD32, Kaspersky and Bitdefender Anti Virus performs. But how good McAfee and Norton Anti Virus perform these days (once they were among the top performers) ? I humbly request to those people who review in the Malware test hub should consider testing McAfee, Norton and the less common Anti Virus softwares so that it helps in decision making process for people when they are considering alternate Anti Virus softwares.

Thank You.

If you listen to some people on this forum, Machine learning and A.I. capabilities, like encryption rollback of ransomware, are only good and effective once the non-American anti-virus firms start implementing them in their feature sets. Until then, they don't work. Or they're not that good. Or they're not as good as traditional heuristics. Or no one can really effectively roll back an infection.

Of course, once they do show up in Kasperskey, Eset, etc., they're suddenly desirable.
