Unknown Error in Mozilla Firefox

Hi everyone,
I'm having trouble with McAfee Scan 8.8, to be precise with a feature that is included in the Patch 1 bundle, but when I try to do a scan I have two instances where Mozilla Firefox received the following error: ids_ss_name ids_ss_version.
I really am not sure what this means. I realize that the problem itself is not very clearly explained by this, not even the nature of the problem seems to be very clear and the information about the error is also obscure.
I've tried using VSE 8.8 via ePo 4.6, but I keep getting the same error message.
Here's the text of the actual message, I hope it will make some things clearer to you guys: Error : another program on your computer would you like to modify with the following add-on: IDS_SS_NAME IDS_SS_VERSION By McAfee, Inc. Location: C:program Files (x86)Common Files McAfeesystem.
Install add-ons only from authors whom you trust. Allow this installation. You can always change your mind at any time by going to the add-ons manager.
That's about it.
