Behavior-based antivirus is extremely difficult, failure-prone, and almost entirely unnecessary because of how secure Linux is, so they don't exist to my knowledge. Signature-based antivirus is basically useless because any security holes exploited by a virus are patched upstream rather than waiting for an antivirus to block it. ClamAV focuses on Windows viruses, not Linux ones, so it can be a signature-based antivirus, but not many people run an email server accessed by Windows devices or other similar services that require ClamAV, so not many people use it, and nobody made any alternatives.
If you're worried about security, focus on hardening and updates, not antiviruses.
Including non-binary people was not the problem. Relevant quote:
"AnitaB.org, the nonprofit that runs the conference, said there was “an increase in participation of self-identifying males” at this year’s event. The nonprofit says it believes allyship from men is important and noted it cannot ban men from attending due to federal nondiscrimination protections in the US."
They identified as male, not non-binary, and the event allowed men to come.
