What Does Antivirus Software Do? Antivirus software is a crucial line of defense against viruses (hence, the name) and other types of malware. It has three main features: Threat Prevention; Threat Detection; Threat Removal ; Traditional antivirus runs scans against your computer looking for current or incoming files that match known bad files or have other indicators of compromise.
Antivirus software often come with a special program that is designed to run every time the PC is booted up.

How does Antivirus Software Work? Antivirus software, sometimes known as anti-malware software, is designed to detect, prevent and take action to disarm or remove malicious software from your computer such as viruses, worms and Trojan horses.
Virus Definitions :This is essentially the first method conventional antivirus software utilize to identify virus. The programs look for signatures to detect new malware. The antivirus companies analyze and extract an exact signature of the file and keep them in a database to which threats are compared and devices are then protected in case the signatures match.
Antivirus software works by identifying similar patterns from its database, or using tools to help predict when an attack will occur (and stopping it before it does). It uses a multi-pronged approach, because viruses can adapt, transform, and get stronger over time.
Once identified, the antivirus software will isolate those files from your system and delete them. You can run a manual scan any time you suspect that your system may be infected with malware of any kind. Some antivirus companies also offer browser extensions that protect you where most virus infections take place, while you're browsing the internet.
