Full origin of antivirus →Frequently Asked Questions
What is the difference between antivirus and anti-malware?
The names now describe much the same product. Antivirus is the older term, from a time when self-copying viruses were the main threat, while anti-malware acknowledges the wider range of harmful software such as ransomware, spyware and trojans. Most current products cover all of these regardless of what they are called.
What is the difference between an antivirus and a firewall?
An antivirus examines files and programmes on the device itself, deciding whether something is harmful. A firewall works at the edge of the network or device, deciding which connections in and out are allowed. They address different stages, which is why systems commonly run both.
How does an antivirus recognise something it has never seen?
Alongside signatures, which are fingerprints of already-known threats, most products watch what a programme actually does, such as encrypting files in bulk or altering system settings, and flag behaviour that matches known attack patterns. This catches some new threats but is not exhaustive.
