Many thanks for the feedback. I'm not in a desperate rush, because although it is very irritating, I don't believe it to be a "life-threatening condition". As I said before, I had exactly the same problem on my machine, about 3 to 4 months ago, and to be honest it's mainly the sheer irritation of having any search results re-directed which begins to wear you down. In the longer term it could of course become more challenging, as the blocked access to Windows Update will mean that the machine gets progressively out of date with patches & fixes.
In terms of the environment concerned, it's a relatively new Dell laptop with Vista Home Premium installed. For anti-virus control, it had AVG free edition, and as I said previously MBAM & Superantispyware are regularly updated and run. There is no "dodgy" software installed, to the best of my knowledge, and Window Update runs in automatic mode (until this problem), to keep things up to date. It also has an up to date installation of Spywareblaster installed, as I learned about that when I had my problems before. UAC is enabled.
The symptoms are :-
1) Cannot run Windows Update - returns an 80072EFE error, which could apparently be caused by just about anything !!
2) Persistent browser (Firefox) re-directs, when you click on the results from a Google search.
3) Oh, and following a little bit more local testing, I have also found that even trying to open a browser window to the Windows Update website is refused, ie the browser reports that it cannot open that domain etc. I tried that with Explorer as well, and got exactly the same problems.
Many thanks & best regards,
NB, for what it's worth, I do know how to get myself around the software / registry environment pretty well, ie I am not a "rank amateur".
