Antivirus software often come with a special program that is designed to run every time the PC is booted up. It does a quick scan of the boot sectors and critical system files, instead of a full disk scan that takes a long time to finish. This comes in particularly handy to catch boot sector viruses, before they get a chance to spread.

Your antivirus software checks the program first, comparing it to known viruses, worms, and other types of malware. Your antivirus software also does “heuristic” checking, checking programs for types of bad behavior that may indicate a new, unknown virus. Antivirus programs also scan other types of files that can contain viruses.

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.

Signature detection is a method by which antivirus keenly scans files that are brought into a system to analyze more likely hazardous files. In essence, antivirus applications come with a directory of already checked-viruses and match the codes and patterns in files and web pages to unique bits and patterns that make up the code of a virus.

While you carry on with your daily work routine, your antivirus software is continually running in the background, checking every file you open, every link you click on, and every website you load. Also known as on-access scanning, resident scanning, or background scanning, this method is always scanning files, every time you open them.

The term malware, a portmanteau for malicious software, refers to computer viruses as well as many other types of malicious software. Antivirus software was originally developed to detect and remove the viruses.
