Ransomware is malware that locks your computer and mobile devices or encrypts your electronic files. When this happens, you can’t get to the data unless you pay a ransom. However return of access is not guaranteed and you should never pay! The ransom can range from several hundred to thousands of dollars. Payments are demanded in bitcoin, a cryptocurrency that is difficult to trace. GrandCrab first appeared in January 2018 and has already claimed 100,000 victims around the world.

How to Insure Against Ransomware

  1. Never open an email attachment if you don't know what it is
    or who sent it.

  2. Make periodic backups of your files to an external drive.
    Then, unplug that drive. Do not leave it connected to
    your computer.

  3. If your devices are attacked immediately visit this website
    on a separate uninfected computer.
