Final answer:
A rootkit can hide its presence, as well as the presence of other malware on a compromised system.
Step-by-step explanation:
A rootkit is a type of malware that is designed to hide its presence and activities on a computer system, making it difficult to detect and remove. However, a rootkit can also hide the presence of other malware, such as viruses or Trojans.
By gaining privileged access to the operating system, a rootkit can control various aspects of the computer, including the ability to manipulate or disable security software. This allows the rootkit to prevent detection and download or install additional malware without the user's knowledge.
Therefore, the statement is true. A rootkit can indeed hide its presence, as well as the presence of other malware on a compromised system.
