[QUOTE="Trident, post: 1028071, member: 99014"] The automatic signature creation is a patented Avast process called Evo-Gen (others have a form of that too). Avast data scientists have developed ways to extract few bytes of similarity from a large, unorganised pile of mess (malware). Using machine learning and behavioural detection, signature is created in a matter of minutes, tested for false positives and delivered as a streaming update.
