Dellenny provides a practical guide on enabling ransomware protection in Windows 11 using Microsoft Defender Antivirus, helping users secure their data from cyber threats.

How to Enable Ransomware Protection in Windows 11

Ransomware attacks can lock or encrypt your files, demanding a ransom to restore access. Fortunately, Windows 11 includes built-in protection through Microsoft Defender Antivirus. To maximize your system’s defenses, you should manually enable ransomware protection. This guide by Dellenny shows you how to do just that.

Step 1: Open Windows Security

Click the Start Menu and type Windows Security.
Select the Windows Security app.

Step 2: Go to Virus & Threat Protection

In the Windows Security window, choose Virus & threat protection.
Scroll to the Ransomware protection section.

Step 3: Enable Controlled Folder Access

Click Manage ransomware protection under the Ransomware protection section.
Toggle Controlled folder access to On.
This setting blocks unauthorized apps from making changes to your protected files.

Step 4: Add Protected Folders (Optional)

Windows protects common folders (Documents, Pictures, Videos, Desktop) by default.
For extra safety, click Protected folders and Add a protected folder to include additional locations.

Step 5: Allow Trusted Applications

If legitimate apps are blocked, click Allow an app through Controlled folder access.
Add any trusted programs required for your workflow.

Extra Tip: Integrate OneDrive File Recovery

Enable OneDrive file recovery for easier file restoration if ransomware strikes.
With OneDrive backups, you can easily roll back affected files to previous versions.

By enabling ransomware protection and configuring controlled folder access, you put strong defenses in place to keep your important files secure. These simple steps can make a big difference in preventing data loss from ransomware attacks.
