Huh... I feel for you with all the weeks of work ahead of you! I've been on the web for 10 years. Seriously, I've no anti-virus software at all. None at all. I don't have a personal firewall, I've never lost any data or files, I've never had a trojan horse, spyware, bots, spiders, key loggers, never had to re-format my hard drive, never re-built my computer, never had to re-install all my software. But, please, don't listen to me. You go right on believing those who'll tell you Macs are just as vulnerable. I mean, they know better, don't they? Don't they?
