| Explanation & Hint:
A virus is best described as: Malicious software or code running on an end device. A virus is a type of malware that, when executed, replicates by modifying other computer programs and inserting its own code. It typically requires some form of user interaction, such as opening an infected email attachment or downloading and running a malicious file, to be activated. Once active, a virus can cause harm by stealing data, logging keystrokes, or corrupting files. |
