Hello again.
- Not quite. The sequence of events was:
(i) Deinstalled McAfee using McAfee deinstallation tool.
(ii) Deinstalled Norton using Norton deinstallation tool.
(iii) Rebooted.
(iv) Reinstalled Norton (I haven't reinstalled McAfee).
(v) Deinstalled Bullguard using Windows deinstall (the Bullguard website says this is how to do it).
2a. A manual check for updates returns error 8000FFFF.
To make sure we're talking about the same thing, I did Control Panel | Windows Update | Check For Updates.
Also perhaps relevant is that I have the automatic search for updates switched off at the moment, as specified in the steps I've been following in the second reply
here.
I had a look around for some advice on error 8000FFFF, and found this. From there, I followed the first link under "General Windows Update Troubleshooting Suggestions" section of the first reply, which took me
here. I followed the instructions to stop a number of services, but the third one (appidsvc) failed with error 1060 (the service doesn't exist).
I haven't gone any further than this (other than to restart the services that I had successfully stopped when following the instructions I linked to) in case this is somehow relevant.
Thanks
