So lately i been trying out a modpack and trinkets are getting flagged as a virus and it deletes from my computer and that causing modpack to not launch and get in need of trinkets because of "Elytra Slot" mod, is this false flag or anything? is this even fixable.

Explanation not needed, since i already know its false flagging but if i include trinkets in my modpack people cant join the modpack because windows defender immediately deletes trinkets in everyone that downloaded the modpack and that makes the modpack unplayable, is it possible to fix this issue with the mod itself?

as per explanation which you apparently already understand: no
this is on windows

Ah, thank you then..
