Pedophilia or child pornography:
In general, pedophilia means sexual touching, activity or solicitation involving an adult and a child or a preadolescent.

Pedophile sites and those showing child pornography can be blocked by Internet service providers.
Scan, Probe or DoS:
All attempts to intrude a TCP or UDP communication port are also usually detected by firewall software. It could also include ICMP requests. This information is usually registered in a log-file ("log") by your firewall software.
Spam (Email, News, IRC):
Spam is unwanted, unsolicited e-mail, usually for advertising purposes, as a provocation or just completely irrelevant and useless which is mass-distributed to large groups of recipients (e-mail), newsletters, (newsgroups) or chat rooms (IRC), and which really pollutes networks.
Virus or Trojan horse:
A virus can be spread in many ways. It could be a worm-like virus that automatically infects other unprotected computers on the network. This type of virus is usually detected by firewall software when trying to connect to any TCP port. It could also be an e-mail virus that sends itself automatically to the other recipients in the address book of the infected computer. The virus can easily forge the shipping address, so it is important, when making such a complaint, to send the complete heading of the message, which contains the IP address of the sender of the virus.
