What is this: winss32.exe?

A system had a virus, 750MHz, 384MB, 20GB, Win98.
I removed the virus by scanning with Norton (updated to 28 February) But the system was still very slow, taking 20 Secs to load Word or other programs or access a file and broadband internet was not working. So I searched the 'run' section of the registry, as mentioned on Symantec's site in connection with various viruses, and found references to these files which I decided were suspicious: c:\windows\WinSS32.exe and c:\program files\srnc\srnc.exe. I removed the references and deleted the files. srnc.exe was in a folder srnc, so I deleted the folder with all files. Problem fixed, internet now works, and Word loads in 3 secs. Question: What are these two files? (srnc may be Signature Revealing Naming Convention for Smalltalk, which is not malicious.)
