Hi, need to reinstall the opera app, first of all, remove the opera app completely, and double-check in program files are any leftovers(in the program files folder for the Opera directory if still exist delete it.) after uninstall is done.
@amaye I think they might have fixed it. It was probably triggered by the web players on GX corner that i think got an update yersterday and bitdefender doesnt think of is a threat any more. Not 100% on that though you gotta give it a try and check for your self.
