hello, just purchased a imac and was surprised how much they came down in price "thank you lord" now for my questions: 1. i have a 3.08 ghz with 8gb of memory with 1tb hard drive and ati radeon hd 4670 256mb. i mainly use the computer to do my finances on line and in leisure time play a little online poker. is it safe for me to play poker without a anti virus on a imac? and from what i read it sounds to me the only way i would get a virus is if i am asked for my administrative password from a web site? also, i watched a video clip about my new computer and it stated that when i am on a web site and i am downloading one thing if the site is dishonest the computer will tell me if its downloading an application rather than what i think im downloading is that right? thank you.
