What is avast definition?

Avast definition refers to the set of instructions or rules that an antivirus software program uses to identify and classify viruses and other types of malicious software. It includes signatures, heuristics, and behavioral analysis techniques to detect and prevent viruses from infecting a computer or device. The Avast definition database is constantly updated with new signatures and other detection techniques as new viruses and malware are discovered. This allows the antivirus software to remain effective against the latest threats to computer security. Avast definitions are an essential component of Avast antivirus software, as they provide the basis for virus detection and protection.
