I prefer the general term malware myself to designate all the programs written with malicious results in mind, because of the ever-increasing mix of insertion and propagation technologies involved.
Yes, I try to stamp-out the word "virus" in this context because many people don't
really understand how these things spread. Human words have human implications. Even "malware" is a bit of a trademark. "Rogue software" is a little more descriptive, I think.
One caution I would make, just from reading this thread, is ... "So, this-or-that tool requires sudo. Can you, with the ordinary account that you use every day, issue that command?"
If so, then they only need to trick you somehow into entering your
password in order to run amok on your Linux
system! They've got "the root password," and that password is ... yours!
The same exploit comes in Windows from being an Administrator ... as most people are. And, heaven help them if they're using the "Home Editions," in which many tools for maintaining system security simply aren't provided.
You may or may not have noticed that Apple, in their latest (El Capitan) OS/X release, instituted changes which restrict the traditionally all-powerful capabilities of "the root user." These changes are not original to them ... they've been available for some time ... but they're the first time that such things have been universally deployed, AFAIK.
