Recently the BT ISecP (Internet Security Pack) that BT have been using to help protect your machine against treats from the Internet has been dis-banded and replaced by the new BT PC Security which is based on the McAfee security software.
In order to upgrade your product on the machine you need to login into the BT Business Broadband Office website (located at: http://www2.btbroadbandoffice.com ) using your primary @btconnect.com E-Mail Address and Password. Once you have logged in, click on Manage BT PC Security and then the Download button.

So far I have thought it has been a good step forward and the new McAfee software is more stable than the previous version.
i had that.
its because your license isnt properly assigned.
first uninstall it
you need to log on to your BT account and at manage services go to the bottom and select manage security
in there you unassign the license and assign it again and re download it and install it and its been fine ever since
