Ransomware

main content

Ransomware is a type of malware that allows cyber criminals to lock a computer from a remote location. A demand for payment is then made in return for unlocking the computer.

In some cases, a pornographic image is used, or there is an an accusation of illegal activity, in an attempt to discourage people from seeking help  

Top Tips for Avoiding Ransomware

  • Don't reply to, or click on links contained in, emails from companies or individuals you do not recognise
  • Don't open attachments unless you’re sure the email is genuine and from a trusted source
  • Don't click on links contained in suspicious messages from social networking sites
  • Backup your data regularly 
  • Make sure you have up-to-date anti-virus software on your computer before you go online
  • Always install software and app updates as soon as prompted
  • Only visit reputable websites
  • Be wary of USB devices (e.g. memory sticks, external hard drives, MP3 players) because these can be used to infect your device with malware.
