Microsoft Defender is an important security tool that comes pre-installed with Windows 11 operating system. Security suites are built right into the operating system to protect your system from malware, but not everyone likes them. Would you like to install an alternative antivirus/antispyware to push Microsoft Defender to the curb? You have two options. Temporarily disable the real-time scanning component of your security suite, or disable the entire suite long-term in favor of competing apps.
Temporarily disable Microsoft Defender real-time antivirus protection
If you want a relatively easy way to disable Microsoft Defender’s real-time scanning engine, follow these steps:
1.[スタート]click the menu search for Windows security app.
2. In the Windows Security app, open [ウイルスと脅威の防止]Click.
3. Selection Manage your settings Under Virus & Threat & Protection settings.
4. You will see a button for real-time protection. erase.
5. When you turn off real-time protection, you will see a red X and a warning message that your computer is vulnerable to attack.
Remember, this only temporarily disables your real-time antivirus protection. Microsoft warns that potentially harmful apps and files downloaded from the internet will not be scanned if real-time protection is disabled. However, scans already scheduled for the system will continue to run.
Install another antivirus program and disable Microsoft Defender
There is another way to completely disable Microsoft Defender instead of just the real-time antivirus feature. Installing a third-party antivirus security suite automatically puts Microsoft Defender on the back burner.
Let’s use AVG Antivirus FREE (opens in new tab) As an example. It’s a free, no-frills Microsoft Defender alternative that’s been around for 20 years. We’re using AVG Antivirus Free in this example, but installing a reputable antivirus program has the same effect as disabling Microsoft Defender.
1. Install your preferred antivirus software (In this case AVG Antivirus Free). This action will automatically disable Microsoft Defender.
2. After installing the software, Open the Windows Security app.
You’ll notice that Windows 11 now recognizes AVG Antivirus (or your preferred antivirus app) protecting your computer.
At this point, the installed antivirus software has full control over real-time and manual scanning of your computer without any intervention from Microsoft Defender. However, if you want more protection, you can click the Microsoft Defender Antivirus option.
Here you can turn on periodic scanning so that the software scans for threats from time to time in the background.
It’s possible to disable Microsoft Defender to varying degrees, but (in most cases) it’s not recommended to run it for an extended period of time without real-time protection on an internet-connected computer.
