How antivirus software works

The antivirus is able to protect a computer by stopping malware. The software is able to read the digital definitions of malware. The scanner searches for known virus definitions inside each file. Once there is a match, the file is either repaired (the malicious code removed), moves to quarantine (a secure location where the file is sandboxed, being unable to affect the system anymore) or deletes the infected file if everything else fails.

Modern antiviruses have the ability to the behavioral scans or heuristic scans, which can detect a malware attack even if its digital definition is not listed in the virus definitions database. In other words, the antivirus watches the behavior of executable files, and if it resembles to the one of a malware attack, it blocks the process.
