I originally posted this log in the ME forum, but have just realised that's probably the wrong one. This isn't an attempt to multiple-post, just an attempt to put right my original mistake - sorry!

The problem is that I can get to Yahoo and Hotmail welcome pages, but get a 'DNS error - cannot find server' page when I click on 'inbox' or any other link in the account. I also cannot submit forms on web pages or post on message boards (am doing this from a friend's pc). Since posting the problem originally, I've discovered that I also cannot get Windows updates. I've tried an alternative browser (Mozilla) and temporarily lowering security settings, but nothing works. Here's the log:

(On the ME forum, it was pointed out that the repeated entry C:\WINDOWS\SYSTEM\U0VF54M.EXE
looked a bit suspicious.)

Any help gratefully received!
