How to Protect against Ransomware

  • Don’t store important data only on your computer’s hard drive.
  • 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.
  • Use an ad blocker to avoid the threat of potentially malicious ads.


  • Never open spam emails or emails from unknown senders.
  • Never download attachments from spam emails or suspicious emails.
  • Never click links in spam emails or suspicious emails.

Anti-ransomware security tools

  • Use a reliable, antivirus product that includes an automatic update module and a real-time scanner.
  • Use a traffic-filtering solution that can provide proactive anti-ransomware protection.
