How To Stop Antivirus In Windows 10

[Cora Auch]

Iwould like a way to fully stop Avast or any antivirus from running. I don't want to uninstall Avast or disable the Shields I want to be able to look in task manager and not see Avast running as a process.

Microsoft Defender Antivirus is a strong security feature that protects your computer from a variety of threats. However, there are times when you need to disable it temporarily or permanently. We shall explore how to do this.

Disabling security software is sometimes necessary, such as during system maintenance or when troubleshooting processes involve incompatible apps or software clashes. In these cases, temporarily disabling MS Defender can help solve the problem more quickly.

John, a freelance graphic designer, was an example of someone who ran into difficulties due to conflicting antivirus programs. He installed a new graphics design software and experienced system performance issues. After investigation, he found his third-party antivirus was incompatible with Microsoft Defender. By following the steps above and disabling Microsoft Defender permanently, John was able to fix the conflicts and carry on with his creative work.

Still, you may need to disable Microsoft Defender temporarily or permanently. Maybe due to compatibility issues or if you want a different antivirus solution. Disabling it can leave your computer at risk, so consider alternative security options.

However, keep in mind that disabling Microsoft Defender Antivirus should only be done when necessary and carefully, as it can make your system vulnerable to potential threats. Before making this decision, weigh the pros and cons. Stay aware of new updates and security measures to create a balanced approach to protecting your digital environment.

To guarantee full security while using a different antivirus program, make sure you update it with the most recent virus definitions and safety patches. This will provide comprehensive protection against malware and other malicious activities.

Remember, while disabling real-time protection has its benefits, it also puts your computer at risk from malware and other threats. So, make sure to turn it back on once you finish the task that needed it disabled. Protecting your computer is key, so take action now to turn off real-time protection in Microsoft Defender Antivirus and stay safe!

Disabling or uninstalling Microsoft Defender Antivirus does give you freedom to choose other cybersecurity solutions. However, it leaves your system vulnerable to potential threats. Make sure you have an alternative antivirus software installed to protect your device from malware and viruses. Compare different options in the market and select the one that meets your needs. Get your system secure today!

We have discussed many ways to disable Microsoft Defender Antivirus service. We have gone through turning off, removing, deleting, getting rid of, and stopping Microsoft Defender. To sum it up, disabling the antivirus service can be useful when alternative security is in place or with software that clashes with it. However, there are risks in doing so.

We have provided instructions on how to disable the antivirus service through Windows Security app and Group Policy Editor. We have also talked about uninstalling third-party software that might be conflicting. This allows users to choose the method that suits their needs.

I am learning python and I scripted and compiled my own executable for my personal use. This is just an app that I made to launch other apps, but this Windows Antivirus Defender keeps seeing it as a trojan and deletes it as if an app I made myself is going to kill my own pc. But I still want the antivirus to stay running in case if there is any other real virus. So, is there any way to stop the antivirus from getting rid of my app?

Hi, I would like to ask if anyone else has this problem, because after installing EIS, Windows Defender is not disabled even though it is shown as disabled in the settings, even after a reboot.

When Eset analyzes some downloaded file or sometimes when I browse web pages both antivirus use a lot of the processor.

Sometimes I notice performance drops,

Please I would be very grateful for any help you can give me.

It's Windows itself that disables Defender when another 3rd party AV registers in the Security Center. You can open a support ticket for further troubleshooting, however, it's unlikely that we'll be able to help. What you could try is rebuilding the WMI repository as per -the-performance-team/wmi-rebuilding-the-wmi-repository/ba-p/373846.

In Windows Security Center -> Threat & Protection setting, verify that you have not enabled Periodic scanning per below screen shot. If Period scanning is enabled, the Windows Defender engine will load at system startup and remaining running regardless of if a scan is being performed.

Smart App Control's primary protection method is its cloud scanning component. Smart App Control like Microsoft Defender uses file "Mark of the Web" (MotW) status criteria for cloud scanning: . There currently exists a vulnerability in MotW: -attacks-use-windows-security-bypass-zero-day-to-drop-malware/ , yet to be patched by Microsoft, that is currently being actively exploited by hackers. In reality and withstanding any vulnerability status, it is rather trivial to strip MotW ADS from a file download.

Since Windows 11 22H2, the Defender service is always on with all AV products. It's the norm now. But it won't cause any CPU or Disk usage, it stays idle but will update signatures at least once a day/after every system start or restart if fast startup is off.

Thank you all very much for your answers, so it is because of Windows 11 and its new update. In my case along with the performance errors with Nvidia GPUs, I think I will have to go back to Windows 10.

Yeah, it uses some ram which will vary from system to system, but there's no CPU usage or any disk activity. Any usual methods like GPO doesn't work to disable the service. Other methods described by turning off tamper protection, taking ownership, changing permission, etc. should work.

Microsoft describes the Sandbox as "Running Windows Defender Antivirus in a sandbox ensures that in the unlikely event of a compromise, malicious actions are limited to the isolated environment, protecting the rest of the system from harm. The goal for the sandboxed components was to ensure that they encompassed the highest risk functionality like scanning untrusted input, expanding containers, and so on. At the same time, we had to minimize the number of interactions between the two layers to avoid a substantial performance cost."

Sandbox is disabled by default and only available for builds 1709 and newer.

It came enabled by default when Windows 11 came out without third-party AV installed. But a few months later they pushed an update somewhere along the way, either part of a Defender update or Windows update, which disabled the sandbox. It even got disabled in Windows Insider editions. Later it was enabled in Windows 11 insider editions once again. So performance impact or some bugs made MS disable it. I for example found a bug when MD won't delete threats when sandbox is enabled. It only blocked, but didn't delete.

It appears to me that the reason MS is running Defender in Win 11 is to support SmartApp cloud scanning. I wonder if SmartApp was permanently disabled, Defender would revert to Win 10 behavior and not load at system startup time? This would be preferable to permanently disabling MD. I assume with MD permanently disabled, it will not auto startup if there's an issue with an installed third party AV real-time protection.

No at least as far as I can find. The setting is a Windows Defender thing. Defender is designed to turn itself off whenever another AV is installed and registers in the security center because you should not run more than one AV. The catch is, Malwarebytes is not an actual AV in the same sense that the other AV companies classify theirs. It is classed as a replacement but retains the ability to run alongside them as well therefore the optional setting to "not register" in the security center.

Porthos: I'm a bit confused by this. I'm running the latest version of Malwarebytes Premium on the latest version of Windows 10 and I have Malwarebytes configured to register with the Windows Security Center. I don't see any evidence that Windows Defender is disabled. It's in my system tray with a green checkmark and the security dashboard shows everything green. Windows Defender still runs its scans. Both products looks like they're coexisting. What would I see to indicate Defender is disabled?

I believe Windows Defender only disables itself in the most recent builds/updates of Windows 10, so if you don't have the latest version/patch installed, it is possible that it is following a past behavior of not automatically disabling itself.
