Restart your computer into safe mode now. (Tapping F8 at the first black screen) Perform the following steps in safe mode:

Double-click on Killbox.exe to run it. Now put a tick by Standard File Kill. In the "Full Path of File to Delete" box, copy and paste each of the following lines one at a time then click on the button that has the red circle with the X in the middle after you enter each file. It will ask for confimation to delete the file. Click Yes. Continue with that same procedure until you have copied and pasted all of these in the "Paste Full Path of File to Delete" box.

C:\WINDOWS\system32\rbwkox.dll
C:\WINDOWS\system32\mscnfg32.exe
C:\WINDOWS\system32\scrgrd.exe

Note: It is possible that Killbox will tell you that one or more files do not exist. If that happens, just continue on with all the files. Be sure you don't miss any.

Exit the Killbox.


START – RUN – type in %temp% OK - Edit – Select all – File – Delete
Delete everything in the C:\Windows\Temp folder or C:\WINNT\temp
Empty the recycle bin

Click Start > Run > and type in:

services.msc

Click OK.

In the services window find

.NET Framework Service

Rightclick and choose "Properties". On the "General" tab under "Service Status" click the "Stop" button to stop the service. Beside "Startup Type" in the dropdown menu select "Disabled". Click Apply then OK. File-Exit the Services utility.

Note: You may get an error here when trying to access the properties of the service. If you do get an error, just select the service and look there in the top left of the main service window and click "Stop" to stop the service. If that gives an error or it is already stopped, just skip this step and proceed with the rest.

------------

In Hijack This, click on the "Open Misc Tools section" button. Next click the "Delete an NT service" button. Copy and paste the following in that box:

.NET Connection Service

Click OK.


Boot and post a new log

Please give feedback on what worked/didn’t work and the current status of your system

Thanks
It seems to have fixed the problem
The Killbox did not find any of the 3 system files.

That looks good - as we are seeing there is another check to clean some hidden stuff

Download the trial version of Ewido Security Suite http://www.ewido.net/en/download/
· Install ewido.
· During the installation, under "Additional Options" uncheck "Install background guard" and "Install scan via context menu".
· Launch ewido
· It will prompt you to update click the OK button and it will go to the main screen
· On the left side of the main screen click update
· Click on Start and let it update.
· DO NOT run a scan yet. You will do that later in safe mode.

Restart your computer into safe mode now. Perform the following steps in safe mode:

Run Ewido:
· Click on scanner
· Put a check by the following before you scan:
o Binder
o Crypter
o Archives
· Click the Start Scan button to start the scan.
· During the scan it will prompt you to clean files, click OK
· When the scan is finished, look at the bottom of the screen and click the Save report button.
· Save the report to your desktop
Post that log
