Thanks to the Internet it is possible to exchange information and have real-time conversations on different issues through newsgroups and chats respectively.

Newsgroups, which are different from mailing lists and use their own Internet transmission system (NNTP), also require constant, efficient protection.

Both systems, apart from enabling communication between people, make it possible to transfer files. Thus, we advise users to be really careful and accept only those files coming from known, reliable senders.
