i am trying cybersecurity for mac. It slowed more my mac than Nod32 in my old pc. Very strange and bad........ Snow leopard Intel core duo 2.4 Ghz 1 Gb DDR2 i will add 2 Gb of memory this week, not only because of Cybersecurity. All apps need more memory by this day but i know Eset security apps to be more light on cpu so i am disappointed.
