@detox It isn't really surprising that it detected known fake-virus signatures. I wonder about how effective it is in general. I've never seen any qualitative comparisons such as those done by AV-Comparatives, for example. It may not even be as effective as Windows Defender, which has been getting better every year and does fairly well in testing.
At my company, I don't use any AV on the firewall, and all LAN clients have local AV protection.
