First: Change the thread's title because you claim that B4A IS a security thread. We are a community of thousands of users here. Noone would use it if it was so.
I also use Huwei phones (like many, many users here). I never got a message like that. Where does it come from? What kind of antivir sw do you have?
PS: When you search for that message you will not find any hints on Google which makes me wonder, too.
