Does anyone know who's program this is? I am using SBC Yahoo with PC-cillin anti-virus program. After I updated windows xp from the internet this program showed up and it turned off the PC-cillin anti-virus function. Is it a Microsoft program? And if so, can I turn it off or delete it so that I can continue using PC-cillin? I'm not very good with computers so if someone can help me out I'll be very grateful.
