I have an android phone that probably has a virus. The symptom is that although I disable screen overlay for all apps (one by one), I still get messages that 'there is a screen overlay'.
Moreover, I tried to install via Google Play the AVG antivirus. The name of the app is not the same as it is in my other android phone, which made me suspicious. Then, I installed and run the AVG antivirus and it resulted that I have 4 viruses and when offered me to click to go to the website, and after clicking I got flooded with messages that my SIM has been damaged etc.
Then I installed Kaspersky and it cannot run because of the screen overlay issue.
Is there a way to complete clean this phone?
