How to solve a sfc.dll detected as PUP?

I am running Windows XP Professional on my work laptop and McAfee.

When I run McAfee I get a 'Potentially Unwanted Program.':
PatchedSFC
C:\WINDOWS\system32\sfc.dll
Delete failed (Clean failed)

I have been reading a lot of different help sites with this topic but I can not really find a solution to the problem. I understand that the file sfc.dll is a critical part of the windows system and that this problem is probably a "false positive" outcome. But I need a completely clean computer for my work.

The first time I got this outcome (few weeks ago) was after a windows automatic software update.

I hope anybody can help me.
