Anti-virus engine to use a database of virus is unlikely to have false positives, but they were unable to determine the new virus, until the developer provides an updated anti-virus database.
As a mature anti-virus software, developers realized that these two methods to detect the location of their own. The most advanced anti-virus software using a combination of both methods.
