Reset and Re-enable your System Restore to remove bad files that have been backed up by Windows. The files in System Restore are protected to prevent any programmes changing them. This is the only way to clean these files: (You will lose all previous restore points which are likely to be infected.)
To reset your restore points, please note that you will need to log into your computer with an account which has full administrator access. You will know if the account has administrator access because you will be able to see the System Restore tab. If the tab is missing, you are logged in under a limited account.

Since the tools we used to scan the computer, as well as tools to delete files and folders, are no longer needed, they should be removed, as well as the folders created by these tools.
Follow these steps to uninstall Combofix.
- Rename Combofix to Uninstall and click on it. That should remove the application.
Manually remove any tool left.
Create a Restore point:

The following is a list of tools and utilities that I like to suggest to people. This list is full of great tools and utilities to help you understand how you got infected and how to keep from getting infected again.
- Spybot Search & Destroy - Uber powerful tool which can search and annhilate nasties that make it onto your system. Now with an Immunize section that will help prevent future infections.
- AdAware - Another very powerful tool which searches and kills nasties that infect your system. AdAware and Spybot Search & Destroy compliment each other very well.
- Windows Updates - It is very important to make sure that both Internet Explorer and Windows are kept current with the latest critical security patches from Microsoft. To do this just start Internet Explorer and select Tools > Windows Update, and follow the online instructions from there.
- Google Toolbar - Free google toolbar that allows you to use the powerful Google search engine from the bar, but also blocks pop up windows.
- Trillian or Miranda-IM - These are Malware free Instant Messenger programs which allow you to connect to multiple IM services in one program! (AOL, Yahoo, ICQ, IRC, MSN)
- ERUNT (Emergency Recovery Utility NT) allows you to keep a complete backup of your registry and restore it when needed. The standard registry backup options that come with Windows back up most of the registry but not all of it. ERUNT however creates a complete backup set, including the Security hive and user related sections. ERUNT is easy to use and since it creates a full backup, there are no options or choices other than to select the location of the backup files. The backup set includes a small executable that will launch the registry restore if needed.
Best wishes!
