Description: Crime is an action or omission, which constitutes an offence and is punishable by law. A crime is an offence that merits community condemnation and punishment, usually by way of fine or imprisonment. Crime takes place when a person deliberately practices deception in order to gain something unlawfully or unfairly. While crime is most commonly committed to obtain benefits of value, it sometimes occurs solely for deceiving another person or entity. Computer crime alternatively referred to as cybercrime, e-crime, electronic crime, or hi-tech crime is an act performed by a knowledgeable computer user, sometimes referred to as a hacker that illegally browses or steals a company's or individuals private information. In some cases, this person or group of individuals may be malicious and destroy or otherwise corrupt the computer or data files. Cyber crime may threaten a person or a nation's security and financial health. Issues surrounding these types of crimes have become high profile, particularly those surrounding hacking, copyright infringement, unwarranted mass-surveillance, extortion, child pornography, and child grooming. This paper focused on the causes, types, detection and prevention of computer crime. The paper also reviews the various forms and types of computer crime practice, their impact and recommendations that will curtail this bad menace.
