WINXP Unknown Startup file name

I have two strange file name in my startup.
i.e. when you run msconfig.
The entire entry is. exactly, as follows:

1) SVDLKYON.
Rundll32.exe “C\Windows\system32\SVDLKYON.dll”,b
Note the “” around the entry and the “,” and small letter afterwards.

2) WIWLWFT
Rundll32.exe “C\Windows\system32\WIWLWFT.dll”,S

These are the only entries with Quotes “…” around them

Anyone has any idea as to what kind of Virus/spyware/rootkit these things are???
Any help would be greatly appreaiated.
