Combofix log is ok. Not sure why it wouldn't run in normal windows. Unless it was avast 4.8's self protection. Safe mode scan with combofix is fine though.
Otcleanit should have removed everything, except perhaps a renamed copy of combofix. Providing if they had been downloaded to your desktop.
Delete combofix.exe from your desktop. Then open c:\ and delete C:\Qoobox and it's contents, c:\combofix.txt if present. You also had Deckards, it can be deleted also along with C:\Deckards. These programs are not installed, so there is no harm in deletion.
You also had a tool from symantec that can probably be removed.
KAV and symantec don't appear in your HJT log other than a couple of enteries that can be fixed with HJT. If you still have HJT run a system scan and fix these lines. If you need HJT again
