Malware is software designed to infiltrate or damage a computer system without the owner's informed consent. The term is a portmanteau of the words malicious and software. The expression is a general term used by computer professionals to mean a variety of forms of hostile, intrusive, or annoying software or program code.

Prepubescent children are not often targeted.
Cybersex, internet sex or net sex is a virtual sex encounter in which two or more persons connected remotely via a computer network send one another sexually explicit messages describing a sexual experience. It is a form of role-playing in which the participants pretend they are having actual sexual relations. In the other ways, this fantasy sex is accomplished by the participants describing their actions and responding to their chat partners in a mostly written form designed to stimulate their own sexual feelings and fantasies. Cybersex may also be accomplished through the use of avatars in a multiuser software environment.
