Typical antivirus solutions detect malware based on virus definitions – a method referred to as blacklisting. Whenever malware is detected, a virus definition is developed and added to the virus definitions database. Hence, when the antivirus encounters a file or application, it compares it with the database and if it is found to be malware then the file is deleted or quarantined. If there is no match then the file or application is allowed to access the system resources. There is a huge risk in this method, as all unknown files are allowed and they could turn out to be malware.
