How to remove an invisible virus? Is it possible without flashing (I don't want to fool around with it)?

Question

Android

The calib battery program is constantly being installed, which I don’t need for nothing, antiviruses don’t yell at it, but I just don’t need it! But antiviruses (play protection and norton) yell at system applications: videos and ... YouTube! When YouTube turns off, it starts full ... If you restart the device, THE PLATE WITH ERROR IN THIS YOUTUBE IS DISPLAYED AND IT IS IMPOSSIBLE TO CLOSE IT! You need to PRESS WITH ONE FINGER TO CLOSE THE PLATE, AND WITH THE SECOND FINGER, QUICKLY PRESS THE SETTINGS BUTTON AND TURN ON THIS YOUTUBE. As soon as YouTube turns on, the sign goes down But the play defense thinks that I should train my fingers for dexterity and even after turning it off, it turns off this YouTube for me. What should I do with all this? I already reset the settings, it did not help.

Let me guess the fly phone? I can say that fly sews adware into the firmware and at the same time it is poorly reflashed. I honestly killed about 20 man-hours for such a miracle and scored.
