Hello. 

The lastest version, 2.5.0 is instant flagged by F-Secure as a Trojan

https://www.f-secure.com/v-descs/trojan-dropper-generic.shtml

Should be good to contact F-Secure or check whats inside the code that trigger a detection.

Same thing for me but windows defender caught mine. It only appears to catch the windows non portable one. The portable one didn't raise any flags. Windows defender identified it as a Trojan:Script/Wacatac.B!ml

I've opened a ticket on the cider collective discord server. Waiting to hear back there.

I second this, installer flagged by smartscreen and cannot be executed. Same goes for the portable version. 

Hey all! We’re working with AV providers to resolve these issues.

Overtime, these should become less and less relevant as our new codesigning certificate gains some new traction and a userbase to verify its authenticity with.

We appreciate your patience!
