Dear Jean,
Thank you for your follow-up. I did indeed use the Submit State feature last night and this morning, your team sent me instructions to run an 'update' and then re-run Exterminate It! on the PC. I just finished that process and the new update wiped it out. I ran my regular anti-spy/anti-virus to double-check and it wasn't able to detect it either. I appreciate the support from both you and your team.

How to Remove Agent.kf from the Windows Registry
The Windows registry stores important system information such as system preferences, user settings, and installed programs details as well as the information about the applications that are automatically run at start-up. Because of this, spyware, malware, and adware often store references to their own files in your Windows registry so that they can automatically launch every time you start up your computer.
To effectively remove Agent.kf from your Windows registry, you must delete all the registry keys and values associated with Agent.kf, which are listed in the Registry Keys and Registry Values sections on this page.
To remove the Agent.kf registry keys and values:
- On the Windows Start menu, click Run.
- In the Open box, type regedit and click OK.
The Registry Editor window opens. This window consists of two panes. The left pane displays folders that represent the registry keys arranged in hierarchical order. The right one lists the registry values of the currently selected registry key. - To delete each registry key listed in the Registry Keys section, do the following:
- Locate the key in the left pane of the Registry Editor window by sequentially expanding the folders according to the path indicated in the Registry Keys section. For example, if the path of a registry key is HKEY_LOCAL_MACHINE\software\FolderA\FolderB\KeyName1, sequentially expand the HKEY_LOCAL_MACHINE, software, FolderA, and FolderB folders.
- Select the key name indicated at the end of the path (KeyName1 in the example above).
- Right-click the key name and select Delete on the menu.
- Click Yes in the Confirm Key Delete dialog box.
- To delete each registry value listed in the Registry Values section, do the following:
- Display the value in the right pane of the Registry Editor window by sequentially expanding the folders in the left pane according to the path indicated in the Registry Values section and selecting the specified key name. For example, if the path of a registry value is HKEY_LOCAL_MACHINE\software\FolderA\FolderB\KeyName2\,valueC=, sequentially expand the HKEY_LOCAL_MACHINE, software, FolderA, and FolderB folders and select the KeyName2 key to display the valueC value in the right pane.
- In the right pane, select the value name indicated after a comma at the end of the path (valueC in the example above).
- Right-click the value name and select Delete on the menu.
- Click Yes in the Confirm Value Delete dialog box.
