AntiVirus threat detected

anything to worry about?

Not really, sounds like a false alarm from antivirus heuristic detection. If you installed plugin via official Dalamud plugin manager, it's been reviewed and accepted as safe.

See antivirus section of Dalamud FAQ for details:

I'm very curios why it was flagged as trojan of all possible threats, it just reads game memory to understand state of TT mini game on screen. Isn't network comms a required component of any malware? Personally, I'd just whitelist entire Dalamud folder, as game injection itself may be seen as suspicious activity, but decision is up to you.

I thrown plugin's dll file into virus total, version 1.10.0.1, same as on your screenshot. Looks like BitDefender & pretty much everyone else agree that it's safe stuff, but some vendors do think it's a malicious program :D
