Now you can remove the cleaning tools and old restore points:


Uninstall ComboFix.exe And all Backups of the files it deleted

• Click START> then RUN
• Now type Combofix /Uninstall in the runbox and click OK. Note the space between the X and the U, it needs to be there.
  

Remove all of the tools we used and the files and folders they created

• DownloadOTCleanIt by OldTimer
• Save it to your Desktop.
• Double click OTCleanIt.exe.
• Click the CleanUp! button.
• If you are prompted to Reboot during the cleanup, select Yes.

The tool will delete itself once it finishes.

If you are prompted to Reboot during the cleanup, select Yes.


You should now set a new Restore Point to prevent infection from any previous Restore Points. The easiest and safest way to do this is:

• Go to Start > All Programs > Accessories > System Tools and click "System Restore".
• Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the Restore Point a name then click "Create". The new Restore Point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
• Go to "Disk Cleanup" which can be found by going to Start > All Programs > Accessories > System Tools.
• Click "OK" to select the partition or drive you desire.
• Click the "More Options" Tab.
• Click "Clean Up" in the System Restore section to remove all previous Restore Points except the newly created one.

More details and screenshots for Disk Cleanup in Windows Vista can be found here.

The system will set new restore points once in about every 24 hours if the computer is on. You can also set your own any time you want. Wait a few days, then set a restore point for the day before. Next day, try restoring to that date to make sure it's working okay.

Let me know if I can be of further help.

System Restore Troubleshoot: Go through this please:

Q.What should I do if System Restore does not work?
A.Try these steps if System Restore does not appear to work:

1.Ensure the System Restore service is running. For more information, see: How can I verify that the System Restore services are running on my machine? (see site)

2.Verify that you have enough free space on all your drives as required by System Restore. If the free space on any partition system restore is monitoring falls below 50 MB, System Restore will suspend and purge out all restore points to free up disk space. It will automatically reactivate when 200 MB+ free space is available. For more information, see How the System Restore Tool Handles Hard-Disk Space Usage. (see site)

3.Examine event logs for any system restore-related errors that could help you identify the problem.

Start> Run> type in eventvwr

Do this on each the System and the Applications logs:
[1]. Click to open the log>
[2]. Look for the Error>
[3] .Right click on the Error> Properties>
[4]. Click on Copy button, top right, below the down arrow >
[5]. Paste here (Ctrl V)
[6].NOTES

Try this and see what you get:
Boot into Safe Mode: Start> Run> cmd> type in:

which is the Restore program, it will prompt with Create vs Restore and you can pick
a Restore point.
