REMOVAL

Note: Removing this Trackware component from the system will likely cause the program that installed it to not function as intended. The uninstaller generally identifies the programs that will not work after uninstallation.

The following instructions pertain to all Symantec antivirus products that support security risk detection.

1. Disable System Restore (Windows Me/XP)
2. Update the definitions.
3. Uninstall the security risk.
4. Run a full system scan and delete all the files detected as Trackware.SAHAgent.
5. Delete the security risk-related keys and values that were added to the registry.
   

For specific details on each of these steps, read the following instructions.

1. To disable System Restore (Windows Me/XP)
If you are running Windows Me or Windows XP, we recommend that you temporarily turn off System Restore. Windows Me/XP uses this feature, which is enabled by default, to restore the files on your computer in case they become damaged. If a virus, worm, or Trojan infects a computer, System Restore may back up the virus, worm, or Trojan on the computer.

Windows prevents outside programs, including antivirus programs, from modifying System Restore. Therefore, antivirus programs or tools cannot remove threats in the System Restore folder. As a result, System Restore has the potential of restoring an infected file on your computer, even after you have cleaned the infected files from all the other locations.

Also, a virus scan may detect a threat in the System Restore folder even though you have removed the threat.

For instructions on how to turn off System Restore, read your Windows documentation, or one of the following articles:

• How to disable or enable Windows Me System Restore
• How to turn off or turn on Windows XP System Restore

Note: When you are completely finished with the removal procedure and are satisfied that the threat has been removed, reenable System Restore by following the instructions in the aforementioned documents.

For additional information, and an alternative to disabling Windows Me System Restore, see the Microsoft Knowledge Base article: Antivirus Tools Cannot Clean Infected Files in the _Restore Folder (Article ID: Q263455).


2. Updating the definitions
To obtain the most recent definitions, start your Symantec program and run LiveUpdate.


3. To uninstall the security risk


This security risk includes an uninstallation applet. In order to uninstall this security risk, complete the following instructions:

1. Click Start > Settings > Control Panel or Start > Control Panel (this varies with the operating system).
   
   
2. In the Control Panel window, double-click Add/Remove Programs.
   
   Windows Me only: If you do not see the Add/Remove Programs icon, click ...view all Control Panel options.
   
   
3. Click "Select CashBack" or "ShopAtHomeSelect Cash Back"
   
   Note: You may need to use the scroll bar to view the whole list.
   If neither of these Control Panel entries exist, the uninstaller can also be obtained by visiting www.shopathomeselect.com/ManualRemove.asp and following the directions there.
   
   
4. Click Add/Remove, Change/Remove, or Remove (this varies with the operating system). Follow the prompts.
   
   Note: After running the Add/Remove programs applet, all the files and registry entries relating to the security risk may have been removed. You will want to run a full system scan to ensure that this is the case. However, it is possible that no files will be detected after using Add/Remove programs.
   

4. Scanning for and deleting the files

1. Start Norton AntiVirus and make sure that it is configured to scan all the files. For more information, read the document, "How to configure Norton AntiVirus to scan all files."
2. Run a full system scan.
3. If any files are detected as Trackware.SAHAgent, click Delete.

5. Deleting security risk-related keys and values from the registry
WARNING: Symantec strongly recommends that you back up the registry before making any changes to it. Incorrect changes to the registry can result in permanent data loss or corrupted files. Modify the specified keys only. Read the document, "How to make a backup of the Windows registry," for instructions.

1. Click Start, and then click Run. (The Run dialog box appears.)
2. Type regedit
   
   Then click OK. (The Registry Editor opens.)
   
   
3. Navigate to the subkey:
   
   HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionRun
   
   
4. In the right pane, delete the relevant value:
   
   "SAHBundle" = "%Temp%undle.exe run"
   "[RANDOM NAME]" = "%System%[RANDOM NAME].exe"
   
   
5. Navigate to and delete the following subkeys:
   
   HKEY_LOCAL_MACHINESOFTWAREClassesCLSID{5F3B3060-09E0-44C6-86F7-BC7B02B57BEE}HKEY_LOCAL_MACHINESOFTWAREClassesCLSID{30402FF4-3E71-4A1C-9B4B-1CD3486A9FB2}
