Thanks for the responses. The two programs that I questioned were called AiOSoftware, and AiOScan. I should have given it a thought that if XP didn't show them, maybe they shouldn't be deleted; but I am such a freak about junk being on my computer. Anyway rather than deleting them, I put AiOSoftware into a search and found that it means All In One software. The blog that I found it on says that AiO had to do with HP products, and since I have an HP All In One Printer/Scanner/Copier - I'm going to go with leaving them installed! Has anyone on this board ever heard of other AiO Software?
