Erasing all her data to get rid of some malware is never basic choice. If you’re walking to carry out it, much better know your success odds because, together I’m about to present you, no all viruses and also malware walk away throughout such a reset. So believe me, you must be mindful of the following information!

The manufacturing facility reset gets rid of malware and viruses, though not in 100% the cases. Nasty rootkits, because that instance, don’t walk away v a reset. And sometimes, malware can resurface indigenous an infected backup, recovery partition, or another maker in the network.

You are watching: If i factory reset my computer will it get rid of viruses

The price to whether a manufacturing facility reset will remove malware and viruses counts on assorted factors, from infection vectors to epidemic targets. And also then, there’s likewise the problem of distinguishing in between malware and viruses. But because a factory reset is pretty much like the atom option, buckle up and also let me display you what you need to know before pressing the red button.

Places whereby malware and also viruses can hide from factory reset

This kind of reset indicates that you eliminate all save on computer data and bring your device to the exact same state it to be in, earlier when it was released indigenous the factory. 

You didn’t gain your computer system infected v malware or viruses as soon as you took it out of the box. So, those this? Why doesn’t a return to the factory state insurance you a virus-free device?

As mind-boggling together it looks, there’s a basic – technical, but simple – explanation because that it:

Some viruses end up in a ar where the factory reset has actually no power:

The firmware

The kernel

The startup code:

MBR (Master boots Record)

VBR (Volume boot Record)

The boot sector


2.Some viruses just sit in a nearby environment and get ago to your pc on the very first occasion:

The backup

The restore partition

Other devices from the network:

A router

A printer

A camera

If the virus is somewhere whereby the factory reset has no access, that is removal may require specialized equipment or even hardware replacement. That’s right; part viruses can damages the hardware.

If the virus is in a backup or on another machine from the network, the factory reset will remove it from your PC. Yet as shortly as you access that back-up or attach your computer to the infected network, it can get back on your PC. This provides it look as if it hadn’t left your computer system in the very first place, which is not true.

The fact is the malware is getting more and more sophisticated. Complicated not just to discover but also to remove. It just makes sense that there will be instances when the factory reset is the just option and instances when, unfortunately, the reset is not a useful option.

Next, I’d like to talk about malware and also virus removal through a manufacturing facility reset separately.

Can malware make it through a factory reset?

Between malware and also viruses, the former is the more comprehensive term. That encompasses any kind of software v malicious intent. No matter exactly how it works, what that does, or just how it spreads, if it reasons harm, that malware. 

Viruses left aside, other main categories the malware that can survive a factory reset would incorporate trojans, worms, and also rootkits. When these space not the common, their ability to escape a reset relies on whereby they reside.

When a hacker writes the password for some malware, crucial part the it suggests indicating the malware’s constituents’ directories ~ above the infected device. A reset will certainly not overwrite the entire operating system. And also depending on whereby the malware will reside, it deserve to make it through the reset.

Some instances the nasty malware

If you operation the reset native a restore partition that the malware currently infected, recovering your data native there might lead come the malware resurfacing.

Rootkits are notorious for your persistence, due to the fact that the minute they acquire into the BIOS, they can theoretically make it through pretty much anything you litter at it.

Worms have a greater chance to resurface as soon as you reconnect your freshly reset an equipment to the infected network since they room standalone programs that self-replicate in ~ a network.

The list of examples might go on and on. The point is the malware defines a wide variety of more or less innovative malicious software application that may survive the manufacturing facility reset relying on various factors.

Even so, over there is consensus among cybersecurity professionals that malware impossible to eliminate is rather difficult to bang into, at least for the typical user. The kind of malware you’re acquiring from surfing the web, including porn websites, is an ext likely indigenous those that will go away v a reset.


Does clean everything a computer system get rid that viruses?

Viruses room a specific form of malware. They connect to legitimate programs or files and are dispersed through emails, flash drives, and, of course, infected files. They only activate adhering to the victim’s deliberate activity of opened the compromised document or application.

Once a virus becomes active on your device, it deserve to disable mechanism functions, modify certain applications, and even encrypt or delete files.

File infectors are a common type of virus the spreads v executable files, commonly within a network. If you reconnect come the exact same network that shares infected files, girlfriend can attend to the virus again soon after the manufacturing facility reset.

Polymorphic viruses, which are much more complex, use self-replication and self-encryption instrument that permit them to adjust their code countless times and evade detection. Such shape-shifters deserve to infect your system images, for this reason if girlfriend opt to restore a previous image, yes sir a opportunity you won’t get rid of it also quickly.

Most usual instances when viruses survive factory reset

The instances when a factory reset will not remove viruses and malware room not that many. Take into consideration the following:

Using an infected recovery partition for the reset

Recovery partitions are the integrated equivalent of restore disks. 

The problem: due to the fact that it lives on your PC, the is feasible for a restore partition to it is in infected. 

The solution: to protect against all risks, don’t usage the recovery partition at all. Instead, download the operating device from a restore CD or USB stick.

Know, however, that this situation, if possible, is much from common. Over there are at this time no malware instances known to particularly target recovery partitions. Consequently, also if yours gets compromised, it would be a repercussion of how the malware spreads and not a deliberate strike on the restore partition.

This detail makes a substantial difference. When the epidemic is tangential, the infected binaries will just run top top the infected system. Adhering to the system restore and also reboot, those binaries should disappear, leaving you v no danger of taking care of the malware again.

For an infected recovery partition to provide you severe problems, the hacker would have to orchestrate a an accurate attack. Developing malware the doesn’t impact a wide selection of gadgets is an unproductive activity that no hacker has actually a genuine interest in. That’s why the odds that you managing a virus the goes after her recovery partition are so low.


Restoring an infected back-up after the factory reset

This is a usual mistake the doesn’t have to do through the reset failing to eliminate the malware. 

The problem: you may have a clean device to occupational with after ~ the reset, however restoring one infected back-up will make it look prefer the manufacturing facility reset didn’t execute anything.

The solution: there space two workarounds for this issue. Girlfriend can choose to provide up ~ above your backup altogether and also accept losing all the data. OR you have the right to keep your backup externally and also only activate it as soon as you have actually a clean OS and an antivirus installed so that you can scan the content.

As far as backup best techniques are concerned, you can keep an outside drive associated to her PC and also regularly create backups ~ above it, or you can use a cloud service. 

The cloud is the safer option because service service providers scan the data you store with castle to save their servers secure. So, technically, if your backup is infected, friend have greater chances to be notified about it when you keep it in the cloud 보다 if you’d keep it ~ above your outside hard drive.

Dealing v a rootkit malware

A rootkit is a program that offers the attacker root-level access to your operation system. When corrupted by malware, the becomes complicated to detect, permit alone come remove. 

You can get that automatically, with a drive-by download, or manually set up by an attacker. The latter implies that the hacker acquired admin accessibility to your maker through a vulnerability exploit (like a privilege escalation) or phishing affix that leaked your password.

The problem: rootkits acquire full control over her system, an interpretation they can likewise evade the software application that was an alleged to detect them. One particular version, additionally known together bootkit, will certainly overwrite the MBR (Master boot Record). Because you’re making use of the MBR because that performing the manufacturing facility reset, you won’t get rid of it not also after the reset. Various other rootkits can obtain into the kernel or firmware, which, again, renders it practically impossible come remove.

The solution: signature scanning and difference scanning, behavioral and memory dump analysis are just a couple of of the an ext sophisticated attempts to identify and also isolate a rootkit. Because that versions that impact the kernel or the firmware, removal may be impossible without committed equipment or even some hardware replacement, together you can’t usage the APIs that Windows generally provides for such tasks. With bootkits removal, boot and also nuke programs (such as DBAN) or disk-partitioning devices (see EaseUS) might be that help.

Connecting come a network v infected devices

With secondary machine infections, her clean pc will likely gain the malware when again the an initial time you affix to it. While somewhat new, together infections space on the rise because of the increased use of cloud solutions for either residence or office networks.

The problem: routers and printers or webcams are few of the many common second devices that can host malware and also easily infect your computer since they are all associated to the very same network.

The solution: to protect against such issues, defend not simply your PC, however every component linked to the network. Maintaining software up to date, obtain the finest security devices you deserve to afford, and tweak protection settings rather than letting them run by the defaults.

Examples the malware that wasn’t eliminated by manufacturing facility reset

Malware that doesn’t go away v a factory reset is no that common, but it is guaranteed to make the headlines for fairly some time once it does show up.

Take, for instance, the Android Trojan xHelper uncovered in 2019. Users would acquire it after gift redirected to websites hosting Android apps. Once they downloaded a compromised app from there, the trojan would install itself together a different, stand-alone service.

Uninstalling the original app did not affect the existence of xHelper, which continued to annoy through spam notifications and also popups. For ten long months, Android individuals complained that xHelper was impossible to remove. Eventually, Malwarebytes for Android app came v an efficient solution against it.



In 2018, ESET reported it had uncovered malware exploiting the UEFI. Lojax, the UEFI-based malware, to be attributed to part Russian state-sponsored hackers. The was hard to eliminate Lojax since it would add UEFI rootkit to the firmware image, v the sole purpose of dropping the malware right into the home windows OS partition, therefore automatically execute itself at startup.


Even an ext recently, in 2019, Kaspersky lab reported one more UEFI rootkit inflicting home windows 10 devices, this time attributed come Chinese hackers. The malware would instantly create a Trojan record on the infected machine, a paper named “IntelUpdate.exe” and located in the Startup Folder. Also if identified and also deleted by the user, it would reinstall itself.


As you can see, UEFI rootkits are specifically concerning. Many civilization would ask us – will certainly a factory reset prevent a hacker that resorts to UEFI rootkits? many likely, no, not until the motherboard’s firmware is updated to a clean, legit version. If this sounds choose Chinese to you, climate there’s a high chance you won’t be able to get escape of such malware in the event you get it yourself.

Understanding what a manufacturing facility reset implies

A manufacturing facility reset is nothing but a finish software reclaim of your computer. The process erases every the info stored ~ above it, pass the maker to the original device state. Every the settings, applications, and also data will certainly be clear all out, leaving you v an empty difficult drive and also all the original mechanism settings your computer system had as soon as it to be released native the factory.

Technically, the manufacturing facility reset is a two-step process that implies:

1.Removing every little thing stored top top it;

2.Restoring the operating system image.

A couple of things come consider before initiating the process

The manufacturing facility reset is irreversible 

Once friend initiate it, over there is no coming back. Those more, if you try to interrupt it, you’ll finish up with an unfunctional PC, in an unstable state, missing essential piece of the puzzle that permits it to role correctly – together it could be there is no the operating device or specific applications or maker drivers.

There’s more than one system restore option

As debated above, over there is a little chance that the recovery partition is compromised. To be 100% certain that you’re getting a clean OS version, you have to use a restore drive rather of the restore partition. Through a restore CD, you will certainly be guided with each step of the process, from formatting the hard drive to installation the OS and setting it up.

How to do a factory reset

As you can imagine, the actions for initiating such a reset vary from one device and one operating system to another. Below, I’ll shot to be quick but still perform the key steps to follow at a glance:
