What are these ghosted folders?

[Personage]

I don't know exactly when it happened, but at some point, I noticed that my Windows 98 machine has added a folder to every single folder on my hard drive called SearchDBDT.  Inside are several files named index_"something".ix and an indexlog.dat.  I don't like the looks of it, and I don't have any idea what it is. Can someone please explain what these folders and files are and how to get rid of them?

Sounds like you have a viris or trojan.........time to reinstall........this is what heppens when you use closed source OS's.
