Just a quick update to keep the board informed.

I think I have now reached the point where Avira is actually uninstalled. It needed several passes, searching for further directories by hand, dealing with the Avira Registry Cleaner's reports of being unable to delete some keys, and then trying it. I have recorded the Cleaner's reporting of its registry cleanup on the two later passes, and took copies with only the "not deleted" lines included -- otherwise the reports are each over 1000 lines.

I am hoping that I now have all components uninstalled, on the basis that the Cleaner is no longer reporting being unable to delete anything that it wants to. My uncertainty is because I've had to do searches by Explorer on names like "avira", "avgnt", etc and it's fully possible there are other variants that I don't remember.

I'm disturbed by the number of Avira folders that even Advanced Uninstaller Pro12 seemed to miss -- in most cases I've relied on it to be very thorough.

But as I say, I think I'm now to the fully uninstalled point and looking forward to doing a full install again. Not least because (hey,call me crazy) I'm not wild about having a running internet connection (such as, for instance, the one I'm using now) with no more than Windows Firewall to secure it.

OK, new status:

After various machinations to get hold of an installer that matched my product activation, I got Avira installed and apparently working. A few successful reboots into full mode with no obvious hiccoughs.

And then, just when I thought this had probably been put to bed and it was time to turn to a secure, dependable driver for the video (which right now is in VGA mode):

I got another blue screen, condition 0x0c4. Either the file causing it wasn't mentioned or the screen resolution wasn't high enough to include it.


Shall I pack up another zip collection?

Sorry, I thought this was starting to work.
And thank you for your continued assistance.
