If your Android device is acting strangely, slowing down, or displaying unusual pop-ups, it might be infected with a virus or malware. One of the most effective ways to remove a persistent virus is to perform a factory reset. This process will restore your device to its original state by erasing all data, apps, and settings. Here’s a step-by-step guide on how to perform a factory reset to remove a virus from your Android device.

Removing your Google account from the device before resetting can help prevent any issues during the reset process.
