Cleaning after no antivirus

Hi,

A friend of mine has had someone "helpful" reinstalling Windows 7
- just is forgot to install antivirus.
Now the computer obviously has some troubles - is it possible to sort out without having to reinstall once again?

When I found out, I immediately installed Avast free Antivirus.

I know that your Malware Removal/Cleaning Procedure specifically asks NOT to run REGISTRY CLEAN - but this had been done before I got involved, sorry.
I also know that Malwarebytes has been run before.

I've not been able to run the RogueKiller - it starts scanning OK, but after a while I get an error: It's a Windows promt coming up saying:
Roguekiller.exe has stopped working - some problem caused it to stop and work correctly. Windows will shut down the program and advise if any solution found.
No solution came up afterwards.

The other requested programs ran OK - logs attached.

Thanks a lot in advance!
