Windows 10: My windows defender won't work, because I acidently allowed a virus instead of selecting on...

Hi, so there was a virus on my Laptop names as "key maker.exe" the wording might be different. My brother installed Bandicam on the laptop and I am guessing he tried to install keymaker to make it work... When i figured it out i tried to remove the virus, but i ACCIDENTALLY clicked on ALLOW and now as you can see in the screen shot down below, my Windows defender/Windows default antivirus program is not working, which is causing my Laptop to slow down and lag.... I need help in removing the virus and making my defender work.Solutions i tried:I installed AVG antivirus app as you can see in

Windows defender does not allow for me to unquarantine items

Hi Michael,

The Real-time protection feature of Windows
Defender stops malware from running on your device. It's possible that this feature is preventing the system from restoring/allowing the affected program. If you're sure that the affected program is virus free, we suggest that you disable the
feature temporarily and try to restore the program. To do this, follow the steps below:

• Type Windows Defender settings in the search bar and press
  Enter.
• Under Windows Defender, disable
  Real-time protection by clicking the toggle button.
• Once you're done, restore the affected file/program and check if the issue persists.

Also, you can allow a quarantined file/program from the Windows
Defender desktop app. If you have the app installed on your device, you can follow these steps:

• Type Windows Defender in the search box, and then select the Desktop app.
• Under the History tab, click on the check box for the affected file/program.
• Select Allow item.

We'll appreciate if you can send us an update.

Windows Defender Not On

Hi,



Welcome to Microsoft Community. Your interest in Windows 10 is much appreciated.



I would suggest you to try the below methods and check:

Method 1:

I would suggest you to run virus scan to make sure the computer is free from virus.

The Microsoft Safety Scanner is a free downloadable security tool that provides on-demand scanning and helps remove virus, spyware, and other malicious software. It works with your existing antivirus software.

Method 2:

Turn the Defender on. Follow the below steps:

• In search, type Defender.
• Now make the option ON by moving the slider accordingly.

Method 3: Run the SFC.

Follow the below steps:

• Open Command Prompt.

• Select “Run as Administrator”.
• Type “sfc /scannow” without quotes and hit
  Enter.

Now check for the issue.



Keep us posted if you face any issues on windows in future. We will be glad to help you.
