I took this answer from (http://forums.mcafeehelp.com/showthread.php?t=223458) and it seems to have worked like a charm:
Go to Start/Run and enter regedit hit the Enter key.
HKEY LOCAL MACHINE/SOFTWARE/MICROSOFT/WINDOWS/CURRENTVERSION/UNINSTALL
Look for any entries in that key that pertain to webroot or spysweeper and delete them. be very careful to only delete those entries and none of the others.
Let us know if it works for you!
