Folder Shield FAQ

What is ransomware?

Ransomware is a type of malware that can lock you out of your computer or prevent you from opening important personal files until you pay a ransom to the attacker.

How does Folder Shield work?

Simply select folders you want to protect and Folder Shield will keep the files inside protected folders safe from ransomware attacks. Your Trend Micro Antivirus software will notify you if suspected ransomware tries to access files protected by Folder Shield.

Why do I get the error message "The following folder cannot be added to Folder Shield protected folders"?

Some folders, such as System and Library folders, cannot be protected using Folder Shield because they are critical resource folders that ensure that your operating system works. Monitoring programs trying to make changes to these type of folders would affect normal functions and impact your Mac's performance.
