I hate to ask you to see if you can do this, but can you try to update Malwarebytes' and run it again. It is out of date quite a bit. Your data base version is 1306 and the current one is 1419.

I also find it unusual that there are no listings like this;
R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Page = http://go.microsoft.com/fwlink/?LinkId=54896
R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Start Page = http://www..com/

O2 - BHO: Adobe PDF Reader Link Helper - {06849E9F-C8D7-4D59-B87D-784B7D6BE0B3} - C:\Archivos de programa\Adobe\Acrobat 7.0\ActiveX\AcroIEHelper.dll
O2 - BHO: Spybot-S&D IE Protection - {53707962-6F74-2D53-2644-206D7942484F} - C:\ARCHIV~1\SPYBOT~1\SDHelper.dll
in the logs. Try renaming HiJackThis.exe to Analyze.exe and run another scan and see if we can see more.

Have you tried Safe Mode with Networking to see if you can access the net that way with the infected drive?
