Today (2023.07.30) Windows Security updated its "don't like" list on my machine and now it won't start/quarantines the app I've been building on R2015b for years. I got around it by excluding the app's installation folder from Windows Security but I find this worrying, especially since this app gets distributed to many others.

Anyone else seen this or have any ideas?

Thank you.

Hi Dane,

This is a common issue where legitimate applications are mistakenly flagged as malware or viruses. This can happen for various reasons. To prevent Windows Security from blocking the app, you can whitelist the application by modifying the settings in Windows. Follow these steps to whitelist the application:

Open Windows Security by searching for it in the Windows search bar.
Navigate to "Virus & threat protection".
Under "Virus & threat protection settings", click on "Manage settings".
Scroll down to the "Exclusions" section and click on "Add or remove exclusions".
Click on "Add an exclusion" and select "Folder" or "File", then add the location of the application.

I hope this helps!
