The majority of your issues have cleaned up nicely.
It sounds like your HOSTS file is 'read only' at this point. The procedures I gave specifically looks for red text (at the very top right) that may read 'Your Hosts file is marked as read only'. If so, there is box to the right of such text 'Make Hosts Writable?' click on that box to make the HOSTS file writable. Then the current potentially bogus HOSTS file content can then be overwitten.ERROR: Cannot create file C:\WINDOWS\System32\DRIVERS\ETC\hosts
If the O1 - entries are allowed to remain they could potentially continue to hijack your PC to 216.130.185.143 ( http://www.dnsstuff.com/tools/ipall....16.130.185.143 ) for questionable purposes and potentially reinstate new and previous infections. What is the purpose of this site to you and why is being so closely protected - do you know that site to be legitimate? Is there another unknown application (from your ISP or other service provider) that has somehow caused restricted access to the HOSTS file? It may be necessary to ask a friend or local shop for assistance.
Try searching for C:\WINDOWS\System32\DRIVERS\ETC\hosts directly - right click on it and see if you can change the properties attribute which could then allow the file to be deleted.
Or, see if you can manually remove the 'O1 - ' entries in HijackThis.
There is also one additional step that also should be done after the above issue is resolved.
