Final answer:
A stealth virus is a type of malware that attempts to hide its code from antivirus software in order to avoid detection. The option D is correct.
Step-by-step explanation:
A Stealth virus is a form of malware designed to conceal its existence and evade detection by antivirus software.
This type of virus employs sophisticated tactics to mask its code, making it challenging for antivirus programs to identify and eliminate.
One common strategy involves code mutation, where the virus alters its code structure regularly to create variations that antivirus signatures may struggle to recognize.
Additionally, some stealth viruses employ encryption techniques, rendering their code indecipherable to traditional antivirus scans.
By adopting these elusive methods, stealth viruses aim to persist undetected within a system, enabling them to execute malicious activities without triggering alarms.
The continuous evolution of these evasion techniques underscores the perpetual cat-and-mouse game between cyber attackers and security systems, highlighting the importance of advanced and adaptive cybersecurity measures.
Hence, the option D is correct, a stealth virus is a type of malware that attempts to hide its code from antivirus software in order to avoid detection.
