How do antivirus software detect potential viruses? Antivirus software scans incoming files and code and comparing them to a database of known malware. These databases are antivirus malware software reviews regularly updated, allowing antivirus programs to spot new threats quickly.

The most popular method by which an antivirus program recognizes an infection is by looking at its digital fingerprint or signature. Every virus has a unique digital fingerprint which sets it apart from other files and programs. The signature is created by comparing certain portions of the virus’s source code against a database of known viruses, and then flagging it if there is a match. Antivirus scanners may also use the heuristic method to analyze the behavior of a file, or the characteristics that are suspicious. This analyzes patterns or trends of a file that can suggest it is a virus, for example, the deletion of large amounts data, monitoring constrained keys or remotely connecting to equipment.

Besides heuristic and signature-based detection Some antivirus programs employ sandboxing. Sandboxing will let a virus run in a virtual environment and observe how it performs and the scanner will see if it is doing what it’s supposed to do. If a virus has been detected, it can be quarantined immediately and deleted from the system.
