Key Takeaways:
– Performing a factory reset on your electronic devices can remove most common viruses and malware.
– Specialized viruses and malware that can survive a factory reset are quite rare.
– It is important to keep your devices up-to-date, install applications from reputable sources, and avoid clicking on unfamiliar links or opening suspicious attachments to prevent future virus infections.
What Is a Factory Reset?
Many electronic devices, including computers and smartphones, include a function called a factory reset that lets you depart back to the original configuration of the device’s drivers and operating system (OS). It deletes any data or applications that weren’t originally installed on the device and returns all settings to their factory defaults. On a phone or taballow, the factory reset option may, however, result in a fresh installation of the current operating system rather than the original one.
Will a Factory Reset Remove Viruses?
In most cases, a factory reset effectively eliminates viruses and malware by returning the OS to its original state. This removes any infected programs or files on your device. However, there are rare instances where highly sophisticated malware, such as trojans or rootkits, can survive a factory reset. One example is the xHelper trojan, which targeted Android devices in 2019 but was later removed by cybersecurity experts.
What If the Virus Returns After Factory Reset?
If your device continues to be infected even after a factory reset, there are a few possibilities to consider. One scenario is that your backup files are infected, and restoring them reintroduces the malware to your device. Another possibility is that the malware has infected your device’s recovery partition, rendering the factory reset ineffective.
Sophisticated malware, like rootkits or bootkits, may also be responsible for reinfection. Some malware can even hide in system peripherals, such as Wi-Fi adapters or webcams, using their onboard storage to preserve itself. These cases are relatively rare, but if you are dealing with such malware, consider scanning your backup drive, inspecting the recovery partition, or wiping your device completely and doing a clean install.
How to Avoid Getting Viruses Again
Taking preventive measures can significantly reduce the risk of future virus infections. Keep your operating system and apps up-to-date by installing the latest updates. Only download and install applications from trusted sources, such as official app stores, to avoid malware. Be cautious of free games or apps from unverified sources.
Exercise caution when clicking on unfamiliar links or opening suspicious attachments in messages or emails. While modern operating systems include built-in malware protection, consider installing additional security software like Malwarebytes for added protection.

The Last Resort
While a type of viruses factory reset can be a powerful solution for removing malware from your devices, it should be considered a last resort due to the time-consuming process of setting up everything again. Practicing good cyber hygiene and taking basic security precautions can greatly reduce the likelihood of encountering malware and keep your devices free from infections.
