Are all computer viruses man-made?

I’m curious if the origin of any successful computer virus is known to NOT have an intentional, human originator. To put it another way, do computer viruses ever “spontaneously” originate through the process of natural selection in the same way biological viruses originate; without an intentional “designer?”

I imagine (though I’m not sure) that it’s possible for sufficiently knowledgable software engineer to make use of software engineering tools like neural networks, genetic algorithms, adversarial networks, etc to write a virus according to his/her specifications, but that’s not what I want to know. I want to know if computer viruses ever begin on their own, and if they don’t, why not?

The three core tenets of evolution by natural selection are descent with modification, variable fitness, and resource limitation. Some scientists say that wherever these conditions are in place, evolution occurs necessarily. Importantly, being alive is not a prerequisite, which is why biological viruses continue to evolve even though they are not technically alive. Richard Dawkins says that thoughts and ideas survive and proliferate through the same mechanism. So, does computer code ever evolve organically without human intervention to form a successfully self-replicating entity? If not, why not?

Why do viruses that wipe boot sectors exist?

In a moment of desperation and without thinking, I executed an .exe file purporting to be a pirated version of a hard-to-find program, forgetting that I had no real-time antivirus active. A few seconds later Malwarebytes (the free version, so not real-time) had been removed from the system. I then hurriedly tried to do a System Restore but sure enough, found that my boot sector had been wiped.

Thankfully, the virus – or maybe more accurately, just malware? – hadn’t touched any of my data, including the image backups on one of my internal disks, so I was able to restore back to a working system within a few hours, but this sobering experience has left me wondering: what exactly is the purpose of such a destructive virus?

I can understand ransomware, cryptominers, or malware that turns my computer into part of a botnet, but what motivation would a malware developer have to wipe out a system’s boot sector? What’s the endgame to doing so? As a bonus question, is there known active malware that goes further and wipes out a user’s actual data?

How do viruses transfer via USB?

I have had an encounter with the paint virus and I noticed it infects OS files in order to target .exe files(it changes an original .exe file to a hidden OS file and renames with a ‘v’ before the initial name and then names a 899KB size of itself as the original .exe for the user to click).

I was able to get rid of it via my anti-virus (probably the part of it that got bound to my OS) but I wasn’t able to undo all the renaming it did to all .exe files on my PC plus the tiny 899KB fakes. I finally wrote a script to delete and do a re-rename.

The other day I was trying to pick a file from a USB flashdrive and I saw the paint virus file (configured my file explorer to always show all hidden files including protected OS files) and permanently deleted it like any other file.

How did this hidden paint virus file hope to get itself copied or transferred to my system without being selected by me from the USB drive when copying other files from it suppose I didn’t delete it?

Which files to scan for viruses (or how to reduce the cost of a full scan) on Linux (Debian)?

It may be irrelevant but anyway: I’m using clamscan to check my system.

The problem is that a full system scan needs far more than one day.
When you plan to do one scan a day, that’s not acceptable.
Additionally the scan sometimes consumes a huge amount of CPU – reducing the performance of the rest of the software.

For me there are two possibilities to tackle this:
Don’t scan the whole system.
Find a way to reduce the workload but still scan the whole system.

The problem: I have no idea if there is a number of directories, big enough to noticeable solve my problem, which can be safely excluded let alone how to scan the whole system in a more efficient way.

Are there any best practices to scan a system for viruses?

Android Viruses Infecting My Phone

My phone has been infected with viruses for 6months now . At first it was just a virus in disguise called “settings” but then it spread to my browsers opening many different sites. I had to disable my browsers. And now there are 3 other viruses on my phone. One called “CLOCKWALLPAPER” second is the “LAKE WORTH ISD” that creates a fake duplicate of an app that I’m using and after I closed that duplicated app the original app starts lagging and then crashes , it also activates the silent mode of my phone. Third one is called “SYSTEM” which pop-up tons of ads that is really annoying and it also makes an app that I’m using to lag and stop working. I try using MALWARE BYTES and BITDEFENDER ANTIVURUS at first it was good and it removes the viruses, and I thought the viruses will be gone permanently but I was wrong , after and an hour or less they get installed again even I have an internet connection or not . So I perform factory reset on my phone to get rid of it. And they were gone . But then later on they get installed again and my phone was now like before.

PLEASE HELP MEE!!!
