Thanks again. I took your advice and installed Ubuntu. I then restored the backup again but, as you suspected, it still had the infection. But I was able, this time, to boot from the Windows installation disk and reset the operating system. This seems to have done the trick, fingers crossed!
The main symptoms of the infection were that the control panel for Avast would immediately close after opening and Windows Update would not run, just returned an error. When I ran AdwCleaner it found 30 suspect registry entries. When I researched them they were indications of infection, a bunch of them were to do with protector.dll. When I deleted those registry entries nothing would run, not even cmd, and even trying to run Adwcleaner from a CD returned an error. The only way to shut down was with the physical power button held for 10s.
