If your PC has been hit by a malware that you cannot remove and remains blocked, see how to do a computer reset

Viruses and malware are spread with devious objectives, often linked to fraudulent commercial policies. The best malware in fact remain hidden on the PC, without attracting attention, only to multiply and open up access to hackers, who can use the resources of our computer. However, these viruses also have self-defense mechanisms and automatically change some Windows settings to make it more difficult for the user to remove them. For example, they can disable the task manager, the registry editor, the antivirus, the firewall and can change the Internet settings, causing connection problems and opening advertising web pages.

If our antivirus has failed to identify the threat in time, there is nothing to do but reset Windows , so that it can return to work without problems. In this guide we will show you how to reset a PC blocked by malware so as to get back to operational as quickly as possible, without wasting too much time on cleaning or restoring too long.

Clean the system before resetting

Before proceeding with a restore, it is always advisable to clean the system of any residual malware and viruses, because in many cases they will interfere with the procedures. In order to quickly clean our computer, we can use the Malwarebytes program .

By running this program and pressing the Scan Now button we will be able to search for any viruses or threats on our computer, so as to be able to remove any possible obstacles for recovery. For greater security, we also recommend scanning the system with Kaspersky Virus Removal Tool .

This tool can be launched to find any type of malware, adware, trojans and viruses, so that you no longer have any infection residues when we decide to proceed with the recovery.

Quick recovery of Windows 10

After cleaning the PC, every moment is good to be able to restore the system! Even if the computer seems faster after using our cleaning tools, remember that many system files may have been damaged during the infection or some files have been replaced with pieces of viruses, which can be reactivated at any moment ( in fact we risk keeping a latent infection always active on the computer!).

To proceed with fast recovery on Windows 10, open the Settings app from the Start menu at the bottom left (we can also click on the gear icon), then take us to the Update and security -> Restore path .

Click on Start in the Reset PC section and choose the item Keep my files ; if the PC to be restored is a laptop, we can also remove the default apps added by the manufacturer by selecting Change Settings> Apps Preinstalled Deactivated . This will start the fast recovery of Windows 10, which will keep all our personal files ( Music, Videos, Documents, Images etc.), but will remove all manually added programs, restore the initial Windows settings and also restore the files system damage possibly caused by the virus.

At the end of the recovery (which can last even more than half an hour, depending on the speed of the disk) we will only have to reinstall our favorite programs and increase the security of the system, so as to avoid further infections on the computer.

Complete Windows restore (10, 8.1 and 7)

If unfortunately the system no longer starts, it is completely blocked at startup or no longer allows access to the desktop, the damage carried out by the virus is high , so we will have to proceed with a complete recovery (a real formatting).

First of all we recover our personal files, which are still saved on our disk and are just waiting to be "saved"! To be able to proceed with a save,

After having recovered all the personal files , we recover a disk image of the version of Windows in use, helping us with the links present in our guide How to download every version of Windows 10, Windows 7 and ; recovered the right ISO image, burn it on a blank CD or DVD or create a USB stick with Windows , so you can proceed with the installation via USB port.

Once we have prepared our diskette or USB memory stick, insert the disk in the reader or the USB stick in a homonymous free port, we set the right boot order and we choose to start the system from the inserted support.

A new window will open with all the partitions on the PC blocked by malware; we select all the partitions present one by one and click on Delete . As soon as the window presents the Unallocated Space as the only partition , select it and then click Next .

The actual installation of Windows will now start, which will require at least half an hour. At the end we will have our Windows as new, formatted and ready to use! We can also restore the personal files we had previously saved and, to avoid problems in the future, we set up a backup of the files on Windows and choose a good free antivirus alternative to Windows Defender, so as to better protect our system and avoid a drastic procedure such as the total formatting of the system.
