You must login as admin to delete this key. It looks like some hotfix did this. Try to roll back the hotfix you applied (or automatic).

Can anybody explain definitely - is this a trojan, is it caused by windows update, is it spyware.  How do we prevent it happening again

OK tnx anyway guys but we've finally sorted this - the AU stands for Auto Update - it is a windows autoupdate file that fails to install properly if the user does not have administrator rights.

The solution is to simply log on as administrator then the registry entry is automatically removed.  No need for spyware detection etc.  No need to manually edit registry.

You can then log on as normal user and everything is ok.

Appears to be an oversight on behalf of Microsoft
