Computer viruses, Trojans, ransomware, and rootkits are different types of malicious programs, called malware, that cyber criminals use to infect computers and devices.

Some of the best ways to defend against malware is to:
- keep all your software and devices up-to-date
- install trusted anti-virus software when possible
- be alert for anyone attempting to trick you into infecting your own system

When all else fails, regular backups are often the only way you can recover.
