- Virus malware is only distributed over the Internet.

Explanation: A virus is malicious code that is attached to a legitimate program or executable file, and requires specific activation, which may include user actions or a time-based event. When activated, a virus can infect the files it has not yet infected, but does not automatically propagate itself to other systems. Self-propagation is a feature of worms. In addition to being distributed over the Internet, viruses are also spread by USB memory sticks, CDs, and DVDs.
