Installing a firewall ad blocker for Android

One of the best ways to get ads off phone is to install a firewall.

A firewall is a special  OS plugin which controls access of your apps to the Internet. Usually, all advertising and virus files are downloaded from the Internet, therefore the firewall can help to identify the saboteur and block it. And in general, the firewall is useful for protecting you phone from being infected.

Note. If you're using a free version of any Android app, it may display advertisement too. It's not a virus, it's just the way its developers can monetize the app and you can pay for your free version. To switch off the banners you have to purchase the full, i.e. the paid version of the program. You're the one to decide whether to do it or not.

Advice. Be sure to install a root manager for Android

The authors of all guides on how to remove ads from your phone/tablet assume that you have a full access to Android file system (exactly where advertising viruses and infected apps are often hiding).

Therefore, root-rights are required for proper operation of almost any antivirus app. Read here how to enable them -

Performing a Hard Reset

If apps uninstallers, firewall and virus scanners don't manage to help you, the only left option is a Hard Reset. Resetting your device to factory settings is, perhaps, the most reliable way to get rid of ads showing up on Android. And you should also take into account the fact that it's a safe and quick option, even though it requires preparation.

Important! You have to make a backup copy of your data and only after that proceed to resetting.

After a Hard Reset your mobile device will have its initial software and memory status, hence it will have no viruses. All user data (SMS, photo, contacts and etc.) stored on your device memory will also be erased.

You can find the information on how to perform a Hard Reset on your particular device on different forums. The risk of screwing up your device and turning it into a “brick” (a failed state) is quite low, if you carefully follow the instructions on resetting given by experienced users.
