I am running Windows XP Professional 64-bit. I recently had to do a system restore, after Windows Update blue-screened my machine while updating the network driver. The system restore went without a hitch, and everything is working as it was, except for the Windows Security Center. Now, it is not recognizing the Comodo firewall and Avast anti-virus that I having running. I have verified that both are running in the task bar and the task manager. Does anyone know how to get Windows to recognize them again? Thanks.
