Okay, I've read enough to know I am now confused. Is is necessary for me to have some type of software that will detect/remove/prevent any malicious activity to my computer when I am surfing the internet? Some reports say Macs are still safe, others say not. I do use bill pay online and purchase things on the internet. I am wondering if not "protecting" my computer is leaving it and me vulnerable to threats on the web. I don't know what to believe after reading various reports so I thought I would ask here from people that KNOW the answer and don't have a $$ investment in the answer.
