I honestly don't expect to be infected anytime soon. Of course I may be wrong, but based on past experience, I doubt it.
I disagree. I am certainly not going to say that my experience applies to everyone. But I strongly believe that my experience of visiting, what is probably thousands of websites and never getting infected, is a good indication of how hard it is to get infected, just from browsing. While I've certainly never specifically tried to find unsafe sites, on the other hand I've never made any attempt to visit only trusted websites. Even if none of the well known websites I've visited, have been compromised at the time, you would think that there would be a good chance that I would gotten infected from some of the rather sketchy websites. But I haven't.
