You're very welcome, Brian.
The file that Avast originally detected and was confirmed by the scan at Jotti was a trojan referred to as Win32.Delf.crq. The various bits & pieces removed with ComboFix were parts of that infection and none of them were parts of other software. Based on the date from the SunBelt link below, it is a fairly newly discovered variant so you should be very glad that you had Avast installed to pick up on it.
