Installation :: Base Filtering Engine Disabled

I thought all my Windows 10 problems were resolved when I finally figured out that Avanquest Powerdesk was preventing explorer from loading the desktop but it seems that was just the beginning of my Win 10 problems.

Once I finally got the desktop to load I then discovered that the start button isn't working, the search bar isn't working, most of the programs that should be in the task bar are not loading, Avast antivirus wasn't running and that the uninstall option in the control panel doesn't work.

Having seen that avast is one possible cause for the start button not working and having tried every other way of fixing the start button that I could find I decided to delete Avast. Because of the uninstall button not working I had to do it the same way I had removed powerdesk - delete the files first and then run cccleaner to clean up the registry entries.

It was when trying to reinstall Avast that I noticed that the install wouldn't run because the Base Filtering Engine Service is failing to start. As so many other services are dependent on that one I suspect that as being a possible cause of all of the other issues (for example none of the security apart from Comodo firewall is running because it is all dependent on this service).

The message in the event viewer appears to indicate that the service does not have sufficient access to be able to run.
