Factory Reset and Viruses: Are They Linked?

In today’s fast-paced digital world, our electronic devices have become indispensable. However, this convenience comes with the ever-present threat of viruses and malware compromising our security and personal data. One common recommendation when faced with such threats is to perform a factory reset. But what exactly does this entail, and is it a foolproof solution? In this article, we will delve into the concept of factory resets and their potential link to eradicating digital intruders, exploring their effectiveness in restoring our devices to a secure state.

Understanding a Factory Reset

A factory reset is a feature available on many modern devices like computers and smartphones. It allows you to restore the device’s operating system and settings to their original state, essentially starting anew. This process removes any programs or files not included with the device.

Effectiveness of a Factory Reset

Yes, a factory reset can be highly effective in removing most viruses and malware. By returning the device to its original state, the reset unintentionally eliminates any infected files or programs. However, it’s worth noting that there are rare cases where certain types of malware can survive the reset.

How a Factory Reset is linked to a Virus

A virus is a type of malicious software designed to infect and harm electronic devices. It replicates and causes damage, often allowing unauthorized access or control by cybercriminals. A factory reset and viruses are indirectly linked when it comes to dealing with certain types of malware on electronic devices.

The reset wipes all data and settings, effectively restoring the device to its original state. This can be highly effective in scenarios where the virus is confined to user-installed applications and data.

Virus Removal

In cases where the virus or malware is limited to user-installed applications and data, a factory reset serves as a means of removing the malicious software. By erasing all user data, including the infected files, the reset effectively eliminates the virus.

Resolving Software Issues

Some viruses or malware can cause severe software problems, leading to device crashes, freezes, or other issues. A factory reset can help resolve such problems by starting afresh with a clean operating system and settings.

Virus Returning After Factory Reset

If a virus keeps coming back even after a factory reset, several scenarios might be at play:

  • The backup being restored to the device is infected, causing the malware to return.
  • The recovery partition, which holds a clean system image for the reset, is infected.
  • Sophisticated malware like rootkits can evade detection and removal during a factory reset.
  • Some malware can hide in the device’s peripherals, re-emerging even after a reset.

What to Do Next

If you encounter persistent malware, consider scanning the backup drive or using a rescue disc to inspect the device thoroughly. You can also wipe the computer’s storage and perform a clean install. For mobile devices, contacting the manufacturer for a complete wipe and a fresh OS installation can be effective.

Prevention is Key

Rather than relying solely on factory resets, prevention is crucial. Keep your device and apps up-to-date with the latest updates. Only install applications from reputable sources, such as official app stores. Avoid clicking on unfamiliar links or opening suspicious attachments. Consider using additional security software like Malwarebytes to complement your device’s built-in protection.


In conclusion, a factory reset can be an effective way to remove most viruses and malware from your device by restoring it to its original state. However, some sophisticated malware may still survive the reset. It’s crucial to take preventive measures, such as keeping your device and apps up-to-date and installing additional security software. With these measures, you can significantly reduce the risk of malware infections and keep your device safe.
