Andres, its clear here and on other sites that lots of folks don't like Norton. What I don't understand is why. People mention things like it being a resource hog etc. I just checked my system and don't see it using much more memory than any other services that run in the background on my system here. I have used Norton AV for years on my home system with no problem. We use Symantec AV here at work (the non-consumer version of Norton AV) and have had no ill effects either.
I certainly understand that there could be better products out there, but I don't have the desire or the time to experiment for the "best" there is. Something that is "good enough" works fine for me. As I stated, I have had no problems with Norton tools.
BTW, this reminds me of similar discussions on Jeep discussion boards where the generally accepted opinion is that certain tranmissions or axles are trash since a friend of a friend of a friend had problems. Although there is little first-hand experience with the failures.
I'm sure some people on this board have had problems with Norton stuff, but I could say the same about any software product ever written. In other words, don't make a decision on AV software just at the recommendation of a few people unless they can give a concrete, first hand example of the problems any AV software has caused (and make sure they are referring to a somewhat recent release of the software).
