I have been a user of the Symantec products for many years and have found them to be better than similar products on the market. My system has remained secure and has performed very well during this time with the utilities being easy to use. However there is an aspect of the 2006 products that is disturbing and has proven to be very difficult to overcome. The products now incorporate Norton Protection Center (NPC) which is design to "validate" your system on boot-up. In other words it checks to see that all your programs that should be running are and that your virus definitions are up-to-date etc etc. This is fine until it finds a problem. Currently, as I write this review, NPC has been running for 4 hours because it has found an issue which it cannot resolve. This is not the first time it has happened, in fact it happens all too regularly. You cannot stop NPC by conventional means. When it is running SystemWorks and Firewall cannot be accessed nor can Liveupdate run. Although the anti-virus and Firewall aspects are in place you cannot modify them, update them or indeed can Liveupdate. NPC does not tell you what it is doing nor will it tell you it has a problem - it just runs and runs. Symantec Support point you at their web site where you can search in a vain attempt to find a solution. The solution I have is to confire msconfig to disable NPC and manually trigger the SystemWorks Utilities when you remeber to do so. I am not impressed by NPC - it brings you more problems than what it solves and detracts from what otherwise is a good product.
