Query: Spamkiller and support are the weak link

McAfee has been a good product over the years for anit-virus protection. However, the Spamkiller product does not measure up to their usual high standard. It is full of bugs and and should have been tested more before it was released. My experience with chat support on two different calls about different issues was a complete waste of time.
