why is anti virus flagging it as a trojan?!
I understand your concern, let me explain:
The reason is the usage of hooks in the code. Hooks are used to listen to keyboard and mouse strokes in the background (to know when to activate or switch between timers). The only way to get around the anti virus when using hooks is paying for a certificate, which as stated at the top of the page, is not viable for me.
As you can see, the timer is very popular with the top streamers, and the project is open source meaning the source code is available on GitHub.
