How to get rid of Windows Defender


Recommended Posts

So,a couple of days back, I installed Windows 8 Pro on a friend' laptop.

Today, he called me and said that he needs to get rid of the Windows Defender.

When inquired about it, I was told that it is randomly spiking up the processor to maximum, even on the newly installed Windows with only a few number of known softwares. I spent some time with it and it was the MsMpEng.exe

I also has had some bad experiences with that thing. Never really understood it completely :wacko:

So, is there a way to get rid of it? What should be done.

And suggest a good, trusted alternative.

Regards...

You don't have to completely disable it. Just turn off the real time protection and that will get rid of the cpu usage. That way at least you can still use it as an on-demand scanner.

Except there's no explorer integration to right click and scan files like you can do with MSE on Windows 7, so that kind of makes it useless even as an on demand scanner.

You can add a right click menu with a registry tweak. Anyway what I meant was you can still use it to occasionally scan in addition to whatever other security software you choose to run. So disable real time protection and it sits in the background hardly using any resources. Then you can use malwarebytes or something as your on demand scanner and Common Sense 2013 pro edition on top of that. Multiple layers of security at no performance cost :)

Rather than just ignoring the problem, did he do an upgrade or clean install? When did he start noticing the problem? Far too many times people whine about something when the cause is completely unrelated to what appears to be the source.

Okay, so thats figured out.

Now, which one should I install in place of Defender?

Don't have much idea in this particular catagory

For a free solution, my vote goes to MSE.

For paid - Eset, hands down.

MSE is Windows Defender in Windows 8.

Is he sure defender is the issue. I just looked at the 4 computers I have Windows 8 installed on and the highest of the 4 is 76mb of ram.

My favourite free is Avast, I always used that until I upgraded to win8. Now I use defender (formerly MSE)

My CPU spikes to 100% sometimes too, when I try to open an .exe I downloaded for example. Its the real time protection scanning the file before it lets you open it. Its not a reason to "get rid" of defender. Removing something for doing what it is supposed to seems daft to me.

However, as i said, Avast is my favourite free anti virus and also has real time scanning (which will still use high CPU)

This. If it's spiking it's an issue caused by something else. He can replace it with another AV but he'll still have issues.

    • I honestly think WSL is one of the coolest things about Windows. The fact that you can type one command and now your computer also runs Linux, without any VM or OS setup is impressive. Yes, it is a VM under the covers, but what is impressive is how seamless and simple it all is.

    • Apple releases iOS 26.5.2 with dozens of security fixes for iPhone by Karthik Mudaliar Apple has released iOS 26.5.2 and iPadOS 26.5.2, which are security-only updates for the iPhone and the iPad. The update brings a bunch of security fixes for WebKit, WebRTC, WebKit Storage, WebKit Canvas, Web Extensions, libxslt, IOGPUFamily, and even the kernel. Some of the WebKit issues that were fixed could have allowed malicious web content to disclose sensitive user information, exfiltrate cross-origin data, crash Safari, or process restricted web content outside the browser sandbox. One notable WebKit Storage bug could let a malicious website to silently hijack clipboard data, according to Apple’s description. Other WebKit-related flaws involved memory corruption, use-after-free bugs, type confusion, out-of-bounds writes, permissions problems, and cross-origin data handling issues. The update also includes three kernel-related fixes. Apple says one of the flaws could let an app write kernel memory or cause unexpected system termination, while another may leak sensitive kernel state, and a third could corrupt kernel memory or terminate the system unexpectedly. Although Apple hasn't described them as remote web attacks, kernel bugs are still important to fix, as they can sometimes be chained with other flaws to escape app or browser restrictions. The updates are available for iPhone 11 and later, iPad Pro 12.9-inch 3rd generation and later, iPad Pro 11-inch 1st generation and later, iPad Air 3rd generation and later, iPad 8th generation and later, and iPad mini 5th generation and later. Similar security fixes also came with the latest update to macOS Tahoe 26.5.2, which Apple released on the same day. That overlap is not surprising, since Safari, WebKit, WebRTC, and other underlying components are shared across Apple’s platforms. Users are advised to update their devices sooner rather than later as these security fixes are crucial. iOS 26.5.2 can be installed from Settings > General > Software Update. Similarly, Mac users can find macOS Tahoe 26.5.2 through System Settings > General > Software Update.
