about:blank hijack in Windows98

Unknown

I've got the about_:blank trojan and I'm running Windows 98. I've tried the solutions posted in several threads here to no avail. One of my first problems is that I don't see a new random .dll in my C:\Windows\System folder after clean out the registry entry (I've got the View setting set to show all files).
Any help would be greatly appreciated. Here's the log:
