😕 Sorry if this seems so lame to some of you. I just bought a 20'' imac 2 months ago. I now have satelite internet. I currently have no aftermarket firewalls or antivirus, mostly because I understood macs are so safe. Well, am I really that safe with this higher speed internet (than dial-up)?? Thanks much for any good response. I love my mac and want to stay safe while surfing.
