Signature-based detection - detects by comparing a virus signature (a binary pattern of known viruses) against files being scanned. Heuristic-based detection - detects behavior in and patterns of code that indicates a virus may be present. Suspicious Code is ran in a runtime virtual environment to further test for virus behavior.

Antivirus software uses virus signatures to precisely detect malicious codes. BitDefender uses an incremental virus signature system based on two file types, cvd and ivd. The first contains the main collection of virus signatures, while the second stores only the latest updates.

This is practically the first method traditional antivirus software employ to identify malware. The programs rely upon signatures to detect new malware. Provided the company has already analyzed and extracted a proper signature of the file that is then kept in a database.

Algorithms can quickly and efficiently scan an object to determine its digital signature. When an anti-malware solution provider identifies an object as malicious, its signature is added to a database of known malware. These repositories may contain hundreds of millions of signatures that identify malicious objects.

Virus signatures are mainly created by companies that write antivirus software. You could use the signature database(s) from a specific antivirus vendor, but there's no point (besides learning) in writing a new antivirus that checks only the same signatures another one already does.

Generic or heuristic detection are the two types of scanning that anti-virus software employs when looking for virus signatures. Generic detection is not as effective as heuristic scanning because it neglects to locate new virus signatures, but it is better at finding new viruses that have been developed from existing virus families.

There are two main methods in use today. Most use a signature-based approach. Some use a heuristic-based approach. In a signature-based approach, the antivirus software keeps a catalog of different virus signatures. When files are scanned, the antivirus software looks for a pattern that matches one of the signatures in the catalog.

The latter is particularly useful when your antivirus software uses behavioral analysis to detect an issue rather than known so-called signature files that guarantee you have a virus.
