Does Factory Reset Remove Virus?

When most people hear the phrase “virus,” they immediately think of a computer infected with malware. However, many people are unaware that a Smartphone may potentially become infected with a virus. That may be relatively inconvenient, especially as it will cause your device’s functionality to slow down. There’s also the dread of being phished, among other things. 

Nonetheless, you can walk out of the situation depending on which path you choose. Some users format their phones, while others immediately perform a factory reset. That leads us to the big question: ‘Will a factory reset remove a virus?’ In this article, we’ll learn all of this and more.

What Is A Factory Reset?

What is the purpose of a factory reset? A factory reset will remove your entire device’s data, including images, videos, applications, settings, and system files. This reset will restore your gadget to its original state, which is the state it was in when it was initially sent from the factory with the most basic set of software.

A factory reset clears all of your data; it will also delete viruses and other unwanted apps. You may use a factory reset on Wi-Fi routers, printers, fax machines, TVs, and other devices in addition to PCs, Macs, and phones.

It is anticipated that restoring your device will remove all of your data, viruses, and spyware. Does this always happen? Will a factory reset get rid of the virus? If you are doubtful, the next section will provide you with the solution.

Why Would You Want To Perform A Factory Reset?

You might wish to execute a factory reset on your smartphone for various reasons.

1. Giving Or Selling Your Gadget To another Person

If you’re giving your smartphone to someone else, make sure you erase all of your data and browsing history beforehand.

2. To Increase Performance

If your device has become sluggish, frozen, or otherwise not operating correctly, you may want to attempt a factory reset. However, if you’ve performed a manual clean-up, we’d only recommend this as a last option. On the other hand, a factory reset may be helpful if the problem is caused by your hard disk or operating system (OS).

3. You Believe Your Laptop Has A Malware Infection

Viruses can be difficult to identify and eliminate, and they might take a long time to do so. That is why using cybersecurity software to secure your devices and preventing the problem in the first place is the best solution. 

But Does A Factory Reset Remove Viruses? 

Does A Factory Reset Remove Viruses

The answer is yes, in a nutshell. Viruses are usually removed by doing a factory reset. However, this is not always the case. (can’t there always have to be a ‘but’?) Because viruses are numerous and ever-evolving, it’s impossible to say if a factory reset would safeguard your device against dangerous apps or viruses.

Let’s use the traditional xHelper as an example. According to sources, it initially appeared in March 2019 and infiltrated thousands of devices by hiding in the codes of unlicensed Android apps purchased outside of the Play Store. There was an infection of over 45,000 Android smartphones in just a few months.

One characteristic of xHelper is that it does not respond to detection or deletion. That is, you will not be able to remove this malware. Despite conducting a factory reset, it reinstalls itself a few hours later and remains active.

In addition to xHelper, other infections may be found on Windows/macOS PCs or iPhones/Android phones. A factory reset may not be able to eliminate certain infections.

Executing a factory reset on your PC, Mac, Android, or iOS device might help you get rid of certain basic malware. That, however, does not function in the case of advanced viruses.

How Do Certain Viruses Manage To Withstand Factory Resets?

Viruses are usually removed by doing a factory reset. But how do some viruses manage to make it through?

Your Backup Is Infected

Before moving any backup data back to your device, be sure it has been scanned for viruses.

Your Recovery Partition Is Infected With A Virus

The recovery partition is a section of your hard disk that stores your device’s factory settings. This partition can become infected with malware in rare situations. As a result, doing a factory reset will not remove the malware.

You Might Be Infected With Rootkit Malware

A rootkit is software that can give you entire (‘root’) access to your operating system. The initial function was to grant authorized users administrative access to a device. On the other hand, Rootkits may now be infected by malware, making them difficult to identify and remove.

Other Devices, Such As Your Printer Are Infected

Malware has the potential to infect your secondary devices such as your printer without your knowledge. When you connect to your computer again, even after you’ve done a factory reset, this device can reinfect your computer.

How To Perform A Factory Reset?

As described above, a factory reset will erase all of your files, documents, and apps from your phone or computer. That is why, while attempting to remove malware, we only advocate a factory reset as a last resort.
