Do you suspect your Android device might be infected with malware or viruses? Android is a much more open platform than iPhone and iPad. This means it's much easier to customize your device and install the apps you want to install. However, it also means that it is much more likely that your Android device can contract malware and viruses. These malicious apps steal your information, kill your battery life, slow down the performance of your device, and eat at your data usage. This wikiHow teaches you how to detect and remove malware on an Android device.

-
Check for apps that have administrative privileges. Malicious apps often try to get administrative privileges to make them harder to uninstall.
