The Add-in "Outlook Scan" (...\Scanotlk.dll) cannot be loaded and has been disabled by Outlook

Yesterday I uninstalled McAfee VirusScan Enterprise v8.5.1 from my development sandbox and each time I open Microsoft Outlook 2007 I receive the following dialog:

---------------------------
Microsoft Office Outlook
---------------------------
The Add-in "Outlook Scan" (C:\Program Files\McAfee\VirusScan Enterprise\Scanotlk.dll) cannot be loaded and has been disabled by Outlook. Please contact the Add-in manufacturer for an update. If no update is available, please uninstall the Add-in.
---------------------------
OK
---------------------------

How to solve this?

Delete the file EXTEND.DAT from the folder %userprofile%\Local Settings\Application Data\Microsoft\Outlook\ and start Microsoft Outlook 2007.

What is EXTEND.DAT?

Extension register themselves in the registry. The Outlook client reads the registry information only once for an extension, and for performance reasons, transfers it to an internal cache. This internal cache is the EXTEND.DAT file, located in the Windows directory. Outlook uses the EXTEND.DAT file to record paths to DLLs for all extensions loaded into Outlook. The first time you begin an Outlook session, or any time after an extension is installed, uninstalled, or upgraded, EXTEND.DAT will be rewritten with the new DLL paths.
