Gotta kill this trojan: winivstr

Since you ran the MGTools before the combofix scan....you need to run the MGTools again. But first I want you to do this:
Copy the bold text below to notepad. Save it as fixME.reg to your desktop. Be sure the "Save as" type is set to "all files" Once you have saved it double click it and allow it to merge with the registry.

* Run avenger.exe by double-clicking on it.
* Do not change any check box options!!
* Copy everything in the Quote box below, and paste it into the Input script here: part of the window:

* Now click the Execute button.
* Click Yes to the prompt to confirm you want to execute.
* Click Yes to the Reboot now? question that will appear when Avenger finishes running.
* Your PC should reboot, if not, reboot it yourself.
* A log file from Avenger will be produced at C:\avenger.txt and it will popup for you to view when you login after reboot.

Now go back and follow the instructions in the proper order:
READ & RUN ME FIRST. Malware Removal Guide

 

Your logs look clean....are you having any other issues?

 

If you are not having any other malware problems, it is time to do our final steps:

1. If we used ComboFix then UNINSTALL COMBOFIX (This uninstall will only work as written if you installed ComboFix on your Desktop like we requested.)
2.
* Click START then RUN
* Now type "%userprofile%\Desktop\cf" /u in the runbox and click OK.
* Note: The space between the cf and the /U, it must be there.
3. If we had you download any registry patches like fixme.reg or fixWLK.reg (or any others), you can delete these files now.
4. You can delete the C:\MGtools folder and the C:\MGtools.exe file. You can also delete the C:\MGlogs.zip
5. If you are running Windows XP or Windows ME, do the below:
* Refer to the cleaning steps in the READ ME for your Window version and see the steps to Disable System Restore which will flush your Restore Points.
* Then reboot and Enable System Restore to create a new clean Restore Point.
6. After doing the above, you should work thru the below link:
