By all means. Get the latest windows and still find yourself being hacked.
Or, next time your PC needs to be reloaded, (Which should be NOW btw, if you got infected, because there is no way to tell how much damage was done.) Why not download a copy of RedHat, Mandrake, Debian, or SUSE Linux and install it instead of windows. Use it for a few days to a week. If you find it doesn't suit the way you like to work with a computer, you can always simply reload windows, and you're no worse off than you were before, but you will at least have tried to get off the windows treadmill.
I've been Windows-free for nearly 4 years. All of my servers run FreeBSD, my security devices run OpenBSD and my desktops run RedHat Linux.
I'm only commenting on this subject because I'm a security engineer by profession and I tend to have accurate and timely information on these subjects near to hand.
