There was a recent poll where Opera came out on top as the most secure browser and this article tries to figure out why. It is indeed the most “secure”, but for a whole different reason. It’s the same reason as Apple used to claim that they didn’t have viruses. It’s just “security by obscurity”. Because the market share is so small, most malware authors won’t bother to target that particular browser. If Opera was #1 in market share, I would posit that it’d be marginally different from any other browser.
