Outlook 2007 - Add-in "McAfee Anti-Spam

Have Outlook 2007 installed on a clients PC and every time I open Outlook I get an error message saying:- The Add-In "McAfee Anti-Spam" C:\program files (x86)\mcafee\msk\mskolplg.dll cannot be loaded and has been disabled by Outlook.

I have checked within Outlook 2007, Tools, Trust, Add-Ins and there is no mention of anything to do with McAfee!!

How can I remove/disable this error if the Add-In isn't within Outlook's Trust?

Assuming you have McAfee installed and want to use it, try these in order:

1. Give the user permission to access Outlook's EXTEND.DAT file:
- Exit Outlook
- Run Windows Explorer
- In the address bar, enter %LocalAppData%\Microsoft\Outlook and press the Enter key
- Right-click on EXTEND.DAT and select Properties
- Uncheck the Hidden check box and make sure the user has access.
- click OK
- Start Outlook

2. If the above doesn't work, delete the EXTEND.DAT file in the location given above.

McAfee was removed from this laptop over a year ago and I had already tried renaming the extend.dat file to extend.old which hadn't worked.  But by deleting the extend.dat file it has resolved the issue.
