i tested norton 2011 on my old computer..it did very well caught 20/20...but not being connected to the internet it did not do very well..i think you guys need to look into that i love norton im going to keep it but i just think that it would be great if it hand that where you are offline and can still get those ugly virues off of there..now like comodo 2011 it has that sandbox where it will do that but i still pefer norton 2011
