Avast! Free Hanging on MSMPENG during first Initial Full System Scan

[REDACTED]

Newly installed Avast! Free.  Ran full scan and it has been an hour and counting on my Windows XP system and Avast! hasn't gotten past C:\Program Files\Microsoft Security Client\MsMpEng.exe.  Infected? Normal?  Thanks for your thoughts.

CPU time is being taken by AvastUI and Unsecapp, so SOMETHING seems to be happening, but I don't know what.  Perhaps the scanned file list isn't being updated and it is running normally in the background?
