I've been using the launcher fine for weeks, but when I tried to open it today Avast saw it as a threat and removed the launcher. When I tried to submit as a false positive, Avast wouldn't let me.
Disabling the antivirus is a temporary fix. When you re-enable the antivirus, it immediately detects the launcher and deletes it, regardless of it being running or not. It also blocks downloads from the Karabor website. EVERY time I try to play I have to disable my antivirus and redownload the launcher.
