10 Best Free and Open Source Anti-Malware Tools

Security is paramount. Security involves defence in depth. Approaching security one step at a time, with consistency and rigour, you can mitigate threats, and keep intruders at bay.

Intruders use a variety of different techniques in an attempt to compromise a system. For example, systems can be attacked by denial of service, cracking, intrusion, snooping (intercepting the data of another user), or viruses/worms/Trojan horses. To have a secure box, a system therefore needs a variety of defences.

Anti-malware is a computer program used to prevent, detect, and remove malware. The most common types of malware include viruses, worms, trojans, ransomware, bots or botnets, adware, spyware, rootkits, fileless malware, and malvertising.
