Unfortunately, I have had the same experience with Symantec products. Over the past 3 years, their Antivirus has slipped. The big problem for me was the product activation that came with Antivirus 2005. I have several failures with this waste of time. I too have noticed some major oversights from their scanner, especially when it comes to trojans. I have since replaced my virus needs and those of my clients with AVG or PCCillan.
