Answer
Hi Rod

The offending entry is still there:

O18 - Filter hijack: text/html - {ba87c3bc-1cf1-4e51-87f3-60680037f49a} - C:\WINDOWS\msvideo.dll

The file msvideo.dll in that location is a trojan.  Please download ComboFix from this link:

http://download.bleepingcomputer.com/sUBs/ComboFix.exe

*Important*-Save it to your desktop.

Double-click on the ComboFix icon found on your desktop. Please note, that once you start ComboFix you should not click anywhere on the ComboFix window as it can cause the program to stall.  If asked to install the Windows Recovery Console, please allow the program to do so.  ComboFix will now start scanning your computer for known infections. This procedure can take some time, so please be patient.  If you see your Windows desktop disappear, do not worry. This is normal and ComboFix will restore your desktop before it is finished. ComboFix may also restart your computer.  Do not intervene.  Eventually you will see a new screen that states the program is almost finished and telling you the programs log file, or report, will be located at C:\ComboFix.txt.  It will then display the log file automatically for you.  Post me that log and a new HJT log in your next follow-up.
