Ransomware is a type of malicious software which locks, or encrypts, part of your computer until a ransom is paid. It is often delivered via email, either through attachments or links to websites where it downloads on to the victim’s computer. There are several steps you can take to help stop criminals from holding you to ransom:
- Back up all of your important files, so you can still access them if you’re infected with ransomware. If this is to an external drive, make sure you unplug it once you’ve backed up as they can become infected too.
- Never click on a link or attachment in an email address unless it’s from a trusted source. Remember, email addresses can be spoofed or made to look very similar to genuine ones.
- If you have a back up, you’ll be able to factory reset your device and restore it. If you can’t reset your devices and restore them, try free decryption tools from https://www.nomoreransom.org/en/index.html
- Unplug your computer or remove your laptop battery as soon as possible to stop other computers or devices on your network becoming infected.
- Never pay the ransom. Those responsible may ask for more money and there is no guarantee you’ll get your files back.
