Windows 10: Taming Windows Defender - How To Allow Unrecognized Apps On My PC

For many years, I have used Rainlendar-Lite as a desktop calendar app with Windows. Recently they advised me of a new version being available, so I downloaded the installer and tried to run it, first the normal way and then with Administrator privileges. In every case, Windows Defender blocks the executable because it doesn't recognize the publisher.

I scanned the install program with Webroot SecureAnywhere v 9.0 and it found no problem. I noticed that Windows Defender is using Public Network settings on my computer, which is NOT connected to a public network, but the settings look exactly the same.

Previously, Windows gave me the option to take responsibility for running unrecognized apps on my system, but apparently that option has been taken away. What is the best way to regain control over my system?

Windows Version 1909 Build 18363.592

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.

 

Defender Firewall will not save "allowed app" rules

I am having a persistent, ongoing problem with allowing apps through Windows Defender Firewall (Windows 10 Pro 1809). Basically, the firewall is not remembering when I add an app to the list.

From the control panel I am going to "Allow apps to communicate through Windows Defender Firewall". One of the apps in question is already listed and I need to continually enable it through the Public connection. But the rule doesn't stick.

Another app is missing from the list so I manually add it, and things work fine for that session. If I restart the system and go back to these rules, the manually added app is no longer in the list, and the already present app in the list has again reverted to Private only. I have to constantly reset these.

Why won't these apps stick in the allowed apps, and how do I fix it?
