There are a number of methods that you can use to protect against malicious adware. It is better to use them together, this will provide stronger protection.

2. Pay for premium versions of popular services. The easiest way to avoid adware is to pay for the service you use. Many Internet services make it possible to use them without ads if you purchase a premium subscription. This helps ensure that malicious adware cannot reach you.
3. Buy devices from trusted companies with built-in security.

Cheap Android devices do not receive security updates and are therefore particularly susceptible to infection and should be avoided.
4. Use an antivirus. Most antivirus programs can block malicious adware. Some malicious adware can block antiviruses, in which case a more aggressive method should be used, which is to use adware removal software. This software can detect and remove adware that has a negative impact on the device.
