Browser dependant malware. With what browser are you more at risk?

Hi forum friends,

I read this blog article at sucuri's: http://blog.sucuri.net/2012/01/ask-sucuri-why-i-only-get-malware-warning-on-certain-browsers.html#more-3022  sucuri article author = dd
It describes that certain malware will check the browser user agent first. If it finds for instance firefox it won't infect. My question now is, do users of certain browsers like IE or Chrome run additional risks?
