What is a database of viruses called?

Answer: anti virus scanner is the name given to the database of viruses that an antivirus software.

What is virus signature database?

A virus signature (also known as a virus definition) is a file or multiple files that are downloaded by a security program to identify a computer virus. The files enable detection of malware by the antivirus (and other antimalware) software in conventional file scanning and breach detection systems.

What is antivirus example?

How do antivirus applications work?

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. If they match, the file is quarantined, means that it is moved to a new and safe location so that it does not infect any other files on the system.

What is signature detection in antivirus?

This is called signature detection. Basically, antivirus applications maintain a database of known viruses and compare the scanned files to that database in order to find out whether the characteristics match.
