Hi, I have Norton Internet Security 2005 and a Soundblaster Audigy 2zs on my system. One is incompatible with the other and each blames the other. This is a well known incompatibility that has been around for ages and through several revisions of the soundcard and security software. There is a fix involving preventing the Soundblaster software from loading. I've applied this fix and am able to use the Soundblaster but I still get irritating glitches with NAV autoprotect loadind. I can fix this by turning NAV on and off a couple of times when the glitch occurs. However, I'm heartily fed up with the constant minor niggle. Either the Soundblaster must go or I must change my internet security software. I'd welcome comments on which would be better for dumping, Norton's or the Audigy. It would be cheaper to replace Norton's but I wonder whether this would be the better option. One must go!
