 Can Factory Reset remove all Viruses?

A factory reset is a very significant way to remove viruses from the computer or any electronic device. Otherwise, the viruses can never be removed from the computer without factory resetting.  We can delete all data saved in the hard drive of the device by running a factory reset.  But some viruses are very complex like malware; we can’t delete them by factory resetting.  To remove that kind of viruses we have to reformat and reinstall the windows.

All your device settings, user data, photos, third-party applications, and other related system data from the internal storage will be deleted when we do factory resetting. But unfortunately, even after doing a factory reset, persistent malware, such as xHelper, cannot be deleted.

As far as the operating system and storage devices are concerned, running a factory reset will restore the computer to its initial power-on state. If you want to do a factory reset select “settings” then go to the option “Update and Security” then click on the “Recovery” button. Then select “Get Started” which is under the heading “Remove everything and reinstall Windows” and follow the instructions that are showing on the screen.

Fully clean the drive

Selecting the option “Fully clean the drive” would most certainly kill all the viruses. If you want to see an alert, you will not be able to return to the previous version of windows by clicking next. When you see your computer is ready, you can press the button for “Reset”. And at last click on “Continue”.

Factory resets do not erase infected files that are saved on backups: when you recover your old data, viruses will return to the device. Before any data is transferred back from the drive to the device, the backup storage system should be thoroughly scanned for virus and malware infections. Some viruses don’t delete by factory resetting. These types of viruses can be destroyed by reinstalling the window.

It is difficult to tell for sure that a factory reset would be the solution to curing your system of malware infection due to the large variety and ever-changing existence of computer viruses. For instance, some kinds of viruses are very complex like xHelper, etc.

xHelper: Unremovable virus (malware)

In 2019, the virus name helper started infecting Android devices.  By hiding in the code of unofficial Android apps downloaded outside of the Play Store, it managed to infiltrate the devices of users. It was even more frustrating was how it was unable to uninstall xHelper. The app will somehow reinstall itself a few hours later, also after a factory reset. 

What happens after factory resetting?

Factory resetting is very helpful in solving the problems from the hard drive, PC, or Windows operating system. Before giving it to a new user or selling it is very necessary to reset your PC. The reset process removes the apps and files installed on the device, and then reinstall Windows and any apps, including trial programs and utilities, that were originally installed by the manufacturer of your PC.

Back up Files

First of all, you should back up your files because the reset process cleans all the personal records from the hard drive of the device. Notice that it can be spread by backups if the PC has a severe malware infection; otherwise, it is vital to ensure that your important business data is securely backed up.

The hard drive of your PC is completely deleted during the factory resetting process and you lose any business, financial and personal files that might be present on the device. You will not interrupt it once the resetting process begins. If you disrupt the operation, your device will be left in an unstable state without an operating system or programs, including software drivers that were originally installed by your PC manufacturer.


The recovery CD-ROMs or recovery partitions are used to restore your PC to factory settings. If you are using CD-ROMs, you will be asked when each disc in order will be inserted. The discs may be directly from the manufacturer of your device, or when you first bought your PC, you may have been guided to make the recovery discs. You can order a package from your computer manufacturer if you do not have a set of recovery discs. The process will prompt you through each stage, including formatting the hard drive of your PC, reinstalling Windows, and setting up Windows for the first time, once the reset process begins via CD-ROMs.

The process is achieved without discs and through a function key such as “F12” or another key while resetting your PC from a recovery partition. The recovery partition was created by the manufacturer of your PC and does not require the launch of the partition using a CD-ROM or another medium. Consult the manual for your PC for the specific key to start the reset process. The method works similar to using recovery CD-ROMs once the resetting process is begun, including prompting you through every step from formatting the hard drive of your PC to setting up Windows for the first time.
