About the only other thing I find in recent references is ESET NOD32. I don't know anything about it, but a couple of different sites have mentioned it, and it appears to be specifically designed for "legacy machines." The comments I've seen were a few months old, but the ESET site still shows it.

The ESET site isn't clear about free/cheap/expen$ive, but on another site one SPGWK complained that "it's a 30-day free trial and then you have to buy it," which was answered with "once you use it you'll want to buy it." No history/references for either genius, but no one else came back to say which one was wrong.

It's possible that a Win98SE machine might be "Mac Safe" - i.e. nobody cares enough to bug you, but I haven't seen anything very recent on numbers of users still up, and even Apple recommends that Macicists use an AV. A year ago, 90%+ of the remaining Win98 machines were reported being in China (it was the most recent thing then with minimal export controls). It seems now that most of the Chinese have bootleg WinXP - or Vista - so '98 may be dwindling there too; and they're not likely to have much since use of the government issued (and monitored) AV and ISP software is "strongly recommended."
