You should look into dual booting between Windows and Ubuntu Linux. With linux you never have to worry about viruses for all practical purposes. With that big of a hard drive, you could easily pinch off about 200 GB for linux and still not be in danger of running out of hard drive space for several years. http://www.ubuntu.com/ It's free, stable, and supported by a legion of programmers worldwide. There is nothing you can do on Windows that you can't do on Linux.

I have an IMAC. My two cents: they just work. They are not as great as the zealots claim nor as bad as the detractors claim. Since moving to IMAC I have eliminated 99.9% of programming incompat/glitches that used to rear their head frequently in PC world. Peace and digital harmony to all!
You are too easily insulted, chief. It was a comical remark. Add a sense of humor module while you are at it.
