i have norton internet security 2007, i understand that its a bundle of diffrent software but it eats a lot of memory. is there any other software that has antivirus, ids, firewall, the whole shabangabang yet doesn't eat a ton of memory? is it as dependable as norton IS 07? is there any other internet security/antivirus software that you'd consider more secure then norton?
also do you need seperate software to detect root kits?
