ok, from what i hear i will not get a virus when using my new mac? only if i download windows will i need a anti-virus program. is it safe for me to do my banking online with my mac with out any anti-virus programs?. What will be some indications from my mac that something may be wrong(meaning phising or anything that could be harmful to my mac). just need to say this, i am 50 yrs old have used pc for the last 10 yrs and cannot believe i wont need anything to protect my computer from viruses or phising sites. i feel like a junkie who cant give it up.
