Need help after removing Trojans

My brothers laptop got infected and I managed to clean off the two trojans found with Microsoft Security Essentials.*

Unfortunately. I'm left with the laptop not being able to download automatic updates (the yellow shield icon just stays at 0%) and I can't use the windows update webpage as it always fails. In addition I'm still getting occasional random tabs opening in firefox and chrome won't work at all. I also get a window called "Just-in-time Script Debugging" popping up which I take as further evidence that damage has been done.

I have scanned the laptop again with MS Malicious software removal tool, Security Essentials, AVG and MalwareBytes and I can't find any infections. Is it possible that the viruses are gone but what ever changes they made to the laptop are causing my problems?

Any advice on how to get the laptop back to normal would be greatly appreciated. Thanks



*AVG and MalwareBytes didn't find anything which is why I downloaded Security Essentials.
 
Thanks for the advice. The hostfile is ok. The only non-commented line is:

127.0.0.1 localhost

I can get to the windows update page but the process fails.

"The website has encountered a problem and cannot display the page you are trying to view."
 
I'm trying to avoid a full re-install if I can but I know it might come to that.

Can you recommend a Live CD that might help?
