Question

Android

Good evening.
Please tell me how to remove the blocker virus on Android 4.4.2 Sony Xperia Z1 Compact phone?
The phone is completely locked, the unlock screen does not work.

Answer 1

I'm posting my own answer. Unfortunately, no pictures, I did everything first.
1. Make a full reset / restore the phone (this is not ours, we are not so interested)
1. Do a hard reset of the phone (red button under the bottom left plug).
2. Turn on the phone with the standard power button.
3. We are waiting for the phone to turn on (you do not need to remove the screen from the lock). Lower the "curtain" (Swipe down from the top of the screen) and on the "Quick Settings" tab, go to "Settings".
4. In the "Security" menu, select "Device Administrators" and uncheck the malware. When prompted, select "Disable". Remember the name of the malicious application.
5. We return to "Settings", go to the "Applications" menu, look for our Malicious application and delete it.
6. All - the virus is removed.
PS This instruction is correct for Sony Xperia Z series phones and above. I got a phone with an application with an icon in the form of Strawberries.
