McAfee Managed Virus Scan add-in problem while starting outlook

Getting Error message while starting Outlook:

The Add-in "Exchange Scan" (C:\Program Files\McAfee\Managed VirusScan\Vscan\OtlkUI.20090520112551.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.

CAUSE: -

1. When a change is made to the location of the email scanning component of VirusScan, this information may not be reflected in the EXTEND.DAT file used by Outlook.
2. Outlook caches its registry settings in the EXTEND.DAT file to improve performance by removing the need to access the registry each time the application is launched. If a change to the registry settings for Outlook have not yet been synchronized with the information in EXTEND.DAT, Outlook will not have the newer information. Deleting EXTEND.DAT requires Outlook to verify the registry and Add-in information before re-creating the file.

NOTE: The Exchange Scan add-on will not show in Tools->Trust Center->Com-Addins.
