How to Protect against Ransomware

- Have backups of important data: on an external drive and/or in the cloud – OneDrive/etc.
- Make sure the operating system and the software you use is up to date, including the latest security updates.
- For daily use, don’t use an administrator account on your computer. Use an account with limited privileges.
- Turn off macros in the Microsoft Office suite – Word, Excel, PowerPoint, etc.
In your browser
- Removed the following plugins from your browsers: Adobe Flash, Adobe Reader, Java and Silverlight. If you absolutely have to use them set the browser to ask you if you want to activate these plugins when needed.
- Adjusted your browsers’ security and privacy settings for increased protection.
- Removed outdated plugins and add-ons from my browsers. Only kept the ones you use on a daily basis and keep them updated to the latest version.
