Solution Uninstalling completely KES and re-installing it will correct the anomaly.
An error may sometimes occur when attempting to uninstall Kaspersky Anti-Virus via Start > Control Panel > Add/Remove Programs.

For example this error on Windows Vista starter: “Your computer already has another localization of a Kaspersky Lab Application installed. Please uninstall it before installing Kaspersky Endpoint Security 10 for Windows”.
Uninstalling it with the old version of the removal utility will not work. In these cases, you can use the latest version kavremvr.exe utility as a solution.

You can now re-install KES10 and it should work.
