I am now since the 90 Internet Security Expert. Was temporarily a few years ago mad at Norton because there were a lot of errors and especially extreme system load. All this is over since at least 2008. The 2010 version is the same as the 2009 peak. Have seven licenses (travel agency terminals and private) of Norton IS2009 / 2010 to run on, all the best. For several years, Kaspersky has with its security software only annoying (running queries if I do this or allow the block or want), even after months of installation and maintenance / adaptation. Norton and Kaspersky top flop again: So the tide turns.
