The appearance of intrusive advertising on the smartphone screen, blocking access to settings and strange pop-up windows often indicate that the device is infected with malware. One of the most widespread and aggressive viruses in the ecosystem Android is considered a Trojan known as Chameleon or “Chameleon”.

Removing a virus requires disabling the administrator rights of the malicious application before uninstalling it. Following the instructions will help restore normal operation of your gadget.
Symptoms of infection and how the virus works
Understanding how malicious code behaves is the first step to successful treatment. Chameleon virus is often disguised as a system process, for example, called System Update or Google Service.

Regularly check the list of applications with administrator rights. Go to your security settings and make sure there are no unnecessary apps there. It is also useful to review the list of installed applications once a month and remove those that you do not use. The cleanliness of the system is the key to its safety.
The main protection against viruses is installing applications only from the official Google Play store and avoiding hacking system protections (root access) unnecessarily.
