Actually, there is more to it than just market share. It's a combination of market share, proportion of that market share that is logged into via interactive sessions and the perception of a predominant lack of technical abilities (OK, not just abilities... A suitably sceptical/paranoid attitude also falls within this category).
Simply put, it's easier to write malware to do things when a user runs it than it is to get the malware in through an exploit and get it to run itself. You therefore target not the platforms with the most installs, but the platforms with the most interactive sessions. To target more specifically within this group, you then consider which platform's users are more likely to be susceptible to social engineering.
This is likely to be the main reason that Windows is the preferred target platform for most malware. Arguments about the sheer volume of Linux servers on the net are somewhat moot when you consider the rarity with which a "typical user" logs into them interactively.
Truth is, without users, PCs are largely useless. As such, the most effective form of malware prevention (removing the user) is impractical. Moving to a different platform will only work until the tipping point is reached and your new choice of platform has an equal or higher proportion of less-technically-able users in interactive sessions than the one you moved from. As such, the only long-term solution is to upgrade your users. Best of luck in achieving that!
