blocking packets which come we get from pcap application

Hi,
I want to block some specific packets in my pcap application. I can
identify those packets.But I am not able to determine how to trash
those packets without sending them to application they are intended
for. Please tell me how can I trash specific packets? Thank you.

How do you identify these packets? Is this something iptables can be told
to do? It can simply DROP those packets if so.

Thanks for reply. I searched the packets' data with mypcap program. If
the data does not contain any malicious word like adult sites have then
it is a clean packet. Otherwise I want to drop the packet or just block
it from going to the intended user. I want to block the packets
containing adult data.
