Which of these operating systems is more prone to viruses and other attacks?

I am hoping to get a vote and maybe a short comment, this is just to help me make a point and possibly win a dissagreement (I won't say what my opinion is until later). OK...Between W98SE, W2000, WXP-home or pro. Meaning if you had a computer that was appropriate for each of the above operating systems with just the standard setup and security settings for the operating system, and you loaded a good (free) anti virus such as AVG and an anti spy, such as spybot, you had DSL, and you visited the same web sites at same times of day etc. Meaning different operating systems everything else being about equal.......Starting with a ''clean'' system, after say 2 weeks, which one do you think would have the most viruses, hi-jackers, spyware, and other uninvited pests?
