Before begining the fix, read this post completely. If there's anything that you do not understand, kindly ask your questions before proceeding. Ensure that there aren't any opened browsers when you are carrying out the procedures below.

It is IMPORTANT that you don't miss a step & perform everything in the correct order/sequence.

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

Please print out or copy these instructions/tutorial to Notepad as the internet will not (while in Safe Mode) be available to you at certain points of the removal process. Make sure to work through all the Steps in the exact order in which they are listed below. If there's anything that you don't understand, ask your question(s) before moving on with the fixes.

Spybot Search and Destroy is outdated. Uninstall version 1.3, then do this:

Download and install Spybot S&D http://security.kolla.de/. Run Spybot and click on the 'Search for Updates' button. Install any updates that are available.

Now click Mode menu and choose 'Advanced Mode'. Next click on Immunize to your left. Click the Immunize button (green cross) on top to Immunize your computer - you should do this each time there is an update. Do NOT enable Spybot TeaTimer Resident protection at this time. What this will do is monitor any system/registry changes and will ask you for permission to change any of these settings. It may also hinder our fix at this point. You may enable it after the fix is complete.

Now click on the 'Spybot-S&D' option on the top left to go back to the main screen. Next click on the 'Check for Problems' button. Let it run the scan. If it finds something, check all those in RED and hit the 'Fix Selected Problems' button. Exit Spybot.
