SystemLook gave us the following:

Since the following steps involve editing the Registry, please create new restore point before proceeding.
System Restore Point - Create
Select: Option Two

Next, open Notepad.
Copy and paste all the text inside the code box below to Notepad:

cd /d "%ProgramFiles%\Microsoft Security Client"
ren "%ProgramFiles%\Microsoft Security Client" "Microsoft Security Client Old"
REG DELETE "HKEY_CLASSES_ROOT\Installer\UpgradeCodes\26D13F39948E1D546B0106B5539504D9" /f
REG DELETE "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UpgradeCodes\26D13F39948E1D546B0106B5539504D9" /f
In Notepad, go to File > Save As...
Save the file to: Desktop
Save the file as: rmvmse.bat
Save type as: All files

On the Desktop, right-click: rmvmse.bat
Select: Run as Administrator
A command prompt window opens and then closes.

When done, restart the computer.

Last, on the Desktop, right-click rmvmse.bat, and select: Delete
Also empty the Recycle Bin.

Go to Start > All Programs > Accessories > Command Prompt
Right-click on the Command Prompt, and select: Run as administrator
At the prompt, copy/paste (with the mouse):

cd C:\Program Files\Microsoft Security Essentials\Backup\amd64
Press: Enter

Now at the new prompt: C:\Program Files\Microsoft Security Essentials\Backup\amd64>
Copy/paste (with the mouse):

Setup.exe /u
Press: Enter

Does setup launch to uninstall MSE?

If still no luck, we can deduct that this new variant of ZeroAccess has discovered and taken advantage of a serious flaw of MSE. It does not have a thorough removal tool.

The following free AVs are available, and you may find more doing a Google search:
Avast! Free:

Avira Free Antivirus 2013 | Download Best Free Antivirus Software
(Note - If it installs a version of the adware/spyware Ask Toolbar, suggest you Uncheck this option.)


still no luck. I think I'm just going to install avast. I can download from internet explorer now which was my main problem and I can just use avast now instead of MSE. thanks a lot for your help guys. really appreciate it

Please install avast! Free, and perform a full scan.

Post back on what it found, if anything.

To find the log, open avast!, and press: Scan Computer

There is an option there: Scan Logs
Click on it, and you get a new window with the Completed scans.

Your scan should be there.

Did you press Apply, and move the files to the Chest?

Please do the following...

Download RogueKiller (Official website)
Select the x64 (64-bit) version.
Click the applicable button to download.
Save to the Desktop.

Close all windows and browsers.

Right-click and select: Run as Administrator

At the program console, wait for the prescan to finish. (Under Status, it says: Prescan finished.)

Press: SCAN

When done, a report opens on the Desktop: RKreport.txt

Please provide the RKreport.txt (Mode: Scan) in your reply.

Follow with Malwarebytes' Anti-Malware:
Save to the Desktop.

MBAM may make changes to the Registry as part of its disinfection routine.
If using other security programs that detect Registry changes, they may interfere or alert you.
Temporarily disable such programs as shown, or permit them to allow the changes:

Right-click the MBAM file, and select: Run as Administrator
When the installation begins, follow the prompts.

At the last prompt of the Setup routine, make sure you leave both of these checked:
Update Malwarebytes' Anti-Malware
Launch Malwarebytes' Anti-Malware

However, uncheck: Enable free trial of Malwarebytes Anti-Malware PRO
Click: Finish

MBAM automatically starts and you are asked to update the program.
If an update is found, the program automatically updates itself.
Press the OK button to close the box and continue.

On the Scanner tab:
Make sure the Perform Full Scan option is selected.
Then click on the Scan button.

If asked to select the drives to scan, leave all the drives selected.
Click on the Start Scan button.

The scan may take some time to complete, so please be patient.

When the scan is finished, a message box shows The scan completed successfully. Click 'Show Results' to display all objects found.
Click OK to close the message box and continue with the removal process.

Back at the main Scanner screen:
Click on the Show Results button to see a list of any malware found.

Make sure everything is checked, and click: Remove Selected

When removal is completed, a report opens in Notepad.

The log is automatically saved and can also be viewed by clicking the Logs tab.

Please copy/paste the entire contents of the MBAM report in your reply.

Exit MBAM when done.

Note: If MBAM encounters a file that is difficult to remove, you are asked to reboot the computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) prevents MBAM from removing all the malware.
