Microsoft keeps on improving security features for the Windows Antivirus. In the Fall Creator Update of 2017, a new feature named Control Folder Access was added to battle ransomware. When you enable this anti-ransomware feature it automatically tracks the apps that are trying to make changes in the folder that is protected.
When this feature blocks a file it will also send you a notification.
This anti-ransomware feature is very useful but still consider it as a preventative measure rather than relying on it completely. Always stay careful while downloading new files, visiting shady websites, or using some external storage device e.g. USB or External HDD. Always backup your data to fully save your self from Ransomware.
You can setup Ransomware data recovery in Windows 10 also.
The Control Folder access feature is disabled by default however enabling it is beneficial as it adds an extra layer of security. To enable or configure Control Folder Access follow these steps
Open the start menu or Windows search by clicking on the start menu or search button on the bottom left corner of your screen. Type Windows Security and open the app.
Click on Virus and Threat Protection and Scroll Down the Ransomware Protection and click on Manage Ransomware Protection.
Here you will see the Control Folder Access option Turn it on if it is turned off.
After this feature is enabled it will provide you with an extra layer of security fighting off ransomware. However, you might come across some files that you want to use but the Windows Antivirus does not trust and blocks it. You can allow access to that certain file by clicking on Block history.
After selecting Block history you will be able to see the blocked files. To unblock your desired file select the file and click on actions and select Allow on Device.
Note: Before allowing any files that are blocked by the control folder access feature please carefully review the file and if it is trustworthy only then allow it on the device.
