What I'm starting to wonder, is why it is any time someone tries to present a reasoned argument against a position, everyone immediately jumps to the conspiracy theory idea that the person arguing against the position is somehow secretly benefiting from it.
Someone goes to a Mac forum and says that in some specific scenario Microsoft wasn't to blame, and all of a sudden you're some giant Apple hating Microsoft apologist. And if you go to a Microsoft forum and say how in this, this, and that way the iPhone is better than Windows Phone, then it's just kind of the reverse of the other example.
Why can't people, like yourself, just grow up and take the time to actually parse a somewhat nuanced argument? Then maybe, and I know this is probably asking for a lot, engage the more rational parts of your mind and come up with an intelligent, nuanced, and reasoned response. As opposed to a rather childish, "You must be part of some conspiracy because you think differently from me!" Though you do help at least demonstrate the truth of the research that shows engineers can be among the most superstitious people... Which is kind of ironic, since engineering is about as logical a profession as there is, yet engineers are more likely to believe in all kinds of crazy things than pretty much anyone else, just like highly intelligent people are more likely to become members of cults. Go figure.
I have said numerous times, over a span of a couple of years, that at some point it will absolutely be necessary to have a Mac AV program. I'm a little amazed it hasn't happened already to be honest. However, AT PRESENT there are no real threats for the platform, so what's the point of an AV program? If all you are finding are Windows specific threats, which cannot affect/infect a Mac, what benefit exactly are you getting from the AV program? Seems to me, it's purely informational and maybe a warm fuzzy feeling akin to picking up a piece of litter and throwing it away. Which is fine, but just recognize that it's just the fulfillment of an emotional need on your part, and that there's absolutely no utility being gained.
Right now the only real possible threat AV programs could protect against on a Mac are VBA viruses for MS Office. Which are really kind of a minor threat to begin with, since they can only affect things like your Word documents. You might think losing your graduate thesis is more than a minor threat, but bigger picture it's trivial compared to say a botnet where your computer might be implicated in conjunction with some criminal act. Every other threat Mac AV programs might protect against are all Windows specific.
