Options
- ACavity virus
- BStealth virus

Explanation
A stealth virus is specifically designed to evade detection by actively hiding its presence from antivirus software and the operating system.
Common mistakes.
- A. A cavity virus attempts to write itself into empty portions of a program file, filling 'cavities' without altering the file's length, but this doesn't inherently make it universally stealthier than a dedicated stealth virus.
- C. A file-extension virus (a less common classification) might attempt to deceive users by using misleading file extensions, but this doesn't prevent antivirus from detecting the malicious code itself.
- D. A macro virus infects applications that use macros (like Microsoft Office documents) and is generally detectable by antivirus software designed to scan document files for malicious macros.
