I just got off the phone with one of the major AV companies as to why a lesser known AV caught a virus that theirs didn't. The details of that delima are not important.
What caught my attention about the conversation was when the technician made mention "we do traditional scanning while others do heuristic scanning". He went on and on about how proven the traditional method was and such. But I couldn't get any detail out of him as to what the difference was?
Is there really a difference in effectiveness, or is this just merely a difference in technique each having their pros and cons? What are the differences?
