What is Polymorphic Malware?

Polymorphic Malware

Polymorphic malware is a harmful computer software that constantly changes to evade detection by anti-malware programmes. The malware's essential function remains the same, but it could alter its signatures, hashes, file names, or keys used to compress and encrypt files. For instance, a spyware programme designed to act as a keylogger will continue to perform that function while changing its signatures. This spyware will then evade detection by anti-malware programmes, which added its former signatures to the database and are unable to detect the new signatures.
