Avast is not listed in Services.
So, avast is not installed or, at least, not properly installed.
You can uninstall, boot, install again, boot... to see if a second installation works.
But, do you have another antivirus installed in this computer? Have you already installed one (which?) in it? Maybe you have a conflict...
Can you start manually the avast! service (C:\ ... \Avast4\ashServ.exe)?
