How to Protect Your PC from Ransomware with Windows Defender

 

Ransomware is a significant threat that can lock users out of their own files until a ransom is paid to recover the data. CBS News recently highlighted the devastating impact of ransomware, focusing on the Scattered Spider group, which caused millions in damage by targeting Las Vegas casinos. While personal computers are less common targets, it’s still crucial to take precautions. 

The best way to protect your system from ransomware is by avoiding sites or downloads likely to contain malware. However, using additional measures like modern antivirus software or built-in protections in Windows can enhance security. Microsoft Defender, integrated into Windows, offers ransomware protection, but users need to enable it manually. To activate ransomware protection in Windows, you must access the Windows Security app. This can be done by searching for “Windows Security” via the Start Menu or settings. Once inside the app, go to “Virus & threat protection” and activate Controlled folder access. 

This feature limits which applications can alter files in crucial folders, such as Documents, Pictures, and others. While trusted programs like Microsoft Office automatically retain access, unauthorized apps cannot modify or even see these folders until granted permission. This restriction is vital for stopping ransomware from encrypting sensitive files. An essential step to further enhance security is backing up your data. Windows Security facilitates this through integration with OneDrive. By logging into your OneDrive account, either through the Windows PC itself or directly in the OneDrive app, you can ensure automatic backups of your important files. 

This provides an additional layer of security, helping to recover encrypted data without paying a ransom. While OneDrive offers convenient cloud backup, it’s also recommended to keep offline backups. These backups are immune to ransomware that might affect your online accounts. Without an offline backup, relying solely on cloud services still leaves a vulnerability. Turning on ransomware protection comes with minor inconveniences, especially for those who save files in common folders. 

For instance, gamers might experience issues with save files being restricted, but this can be remedied by adding specific apps to the access list or adjusting where files are saved. Overall, securing your PC against ransomware involves enabling the built-in features in Windows, setting up OneDrive backups, and keeping an offline backup for extra safety. Taking these steps ensures you’re prepared in case your files are ever threatened by ransomware attacks.
