Creating a computer virus is unethical because viruses do things on people's computer's without their permission. Creating and distributing a computer virus would be like using their computer without their consent. Also, depending on what the computer virus does, you could incur a number of other ethical problems - like stealing, harassment, etc.
There could be many reasons. The computer could have a malfunction and accidentally create a virus. Or, a person could create a virus and send it to you through an e-mail, an ad on the internet, etc.
