That log is not complete and is actually from the fourth run of Combofix, I need to see the other logs from the other CF scans, they will be here C:\Qoobox\ and will be in a format such as follows:
C:\qoobox\ComboFix2.txt 2011-10-03 17:07:26
C:\qoobox\ComboFix3.txt 2011-10-03 16:42:53
C:\qoobox\ComboFix4.txt 2011-10-03 15:56:10
The above are listed as examples and dates/times will differ slightly in yours. The higher the number the earlier the scan, in the above example Combofix4.txt is from the first run of CF as can be see from the time. Therefore let me see the scans you have done in reverse order, higher number first.
Also let me see this log if it exists C:\Qoobox\ComboFix-quarantined-files.txt
