From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Depends on the malware.
With total access, nothing would prevent the malicious code from modifying the task viewer itself to make it ignore the resources it is using.
Accounting for every way malware might be discovered is difficult, but with enough system access, it's all possible.
It also depends on the viewer. I remember using
prctl()in C to chamge a process name and top showed my change but htop didn't. I'm sure a competent malware writer would be able to trick it thoughiirc, postgresql renames itself in htop to show its current status and which database it's operating on
