What is Ransomware?
Ransomware refers to malicious software that can encrypt important files on your PC to make them inaccessible and then threaten to publish or delete your files until a sum of money (ransom) is paid. Even after paying the ransom, there is no guarantee that you can recover your files.
What is Ransomware Protection?
Ransomware Protection secures your personal photos, documents, and other files from being modified, deleted, or encrypted by ransomware attacks. This feature scans for and automatically secures folders that may contain personal data and allows you to specify other folders you want to protect from untrusted applications. Additionally, you can specify which applications are allowed to modify the files in your protected folders and which applications are always blocked. Ransomware Protection is enabled by default when you install Avast One.
Which folders does Ransomware Protection secure?
Ransomware Protection automatically secures folders where you might store personal data, such as the Documents and Pictures folders. To manually add other protected folders:
- Select Explore ▸ Ransomware Protection ▸ View protected folders.
- Click + Protect a new folder, then select a folder and click OK.
To remove a folder, hover your cursor over the relevant folder's panel, click the X icon that appears, then click Yes, stop protecting.
Can I specify which file types Ransomware Protection secures?

- Strict Mode: you are notified and asked for permission each time a new application attempts to modify files in your protected folders. Selecting this option may result in frequent and potentially annoying alerts.
