Well, that's too bad. I'll keep downloading new definitions files each week till the SS&D folks stop providing them for the current version of Spybot.
BTW, I did eventually get Spybot to do a complete scan on the Win98 machine. The system became sluggish to the point of unusability and I finally decided to do a clean install on the additional hard disk drive I'd bought with that possibility in mind. Next time I ran Spybot, it worked wonderfully.
