Thanks BW.
First, I can't see anything that's making me worry too much.
There are a couple of obvious ones that just need tidying up:
R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Start Page = http://www.ebay.co.uk/MainUKC1.html
I reckon you only need one of them.
and:
R0 - HKLM\Software\Microsoft\Internet Explorer\Search,SearchAssistant =
R3 - Default URLSearchHook is missing
plus:
O9 - Extra button: (no name) - {CD67F990-D8E9-11d2-98FE-00C0F0318AFE} - (no file)
I'll have alook at a couple of others when I get back in tonight.
Just one other thought, did you install HJT to the desktop? If so it would be better to install it to it's own folder in, say, the C:\Temp\HJT and run it again.
There may be a couple of other steps such as switching off Restore and starting up in Safe Mode, but I'm not sure they would help here. Although, it might be worthwhile starting in safe mode with networking enabled and seeing if you can reach the update pages that way.
Take care.
