How antivirus works??
Each antivirus works on its directory. Company put the directory in the antivirus and declare all the names of viruses , Trojans, spywares etc. wheneven any identity of any file does match to its directory names it eliminate that file moreover alert us about that malicious activity. Updation Is necessary because number of new viruses comes in network and company patch that threats to its directory and that is why antivirus require updations.
