No, but if you use a global anti-virus such as nortons that would be the way to do it.
For ur kind information, AD cannot be used as a proxy filter.
IPSEC / Firewall blocking – This is the most pervasive blocking usually perform. IPSEC filtering may deploy via GPO to individual computers / may be deployed to the network’s internet gateway for blocking. To block a specific site, a generic policy only requires knowledge of the particular site’s IP address and a broad rule can set as block/deny all traffic with this address. While IPSEC operates at the operating system level, most routers have internal firewalls. If u cannot ping them, then the IP’s are being filtered or even if u can ping, but can not browse then it is a good indication that a narrow rule has been set restricting the protocol/port.
U may also use IE > Internet Options for the same purpose.
