In an Earth that has long since reached the Singularity, the point at which human life can be uploaded into a digital simulation, and that most humans live inside this simulated world, outside is a small number of humans that keep the systems running, why they do this is not important, lets say it just happens
Then a piece of Malware or a computer virus turns up and starts to do lots of damage in the simulated world
Lets make some assumptions:
- Either no help from outside the simulation, or anyone outside the simulation can only watch, they are unable to assist.
- The Malware/Virus, must act like a Zombie acts, it moves slowly, but once it infects a file (person) that file must become malware capable of infecting other files
- Can be blocked by firewalls, however if enough malware presence takes place they can breakdown the firewall
- Once infected, the file is not instantly killed and turned, then die slowly and the turn into a Zombie
- Once a file is infect it needs to be irreversible, that file (person) is permanently corrupted (dead)
- There must be a way inside the Simulation to fight it, similar to shooting it in the head. but this is just what the simulation people see, it doesn't happen like that
How would this malware act from outside the simulation? if we assume those inside the simulation see Zombies. then how would the outside observer see this happening from the computer end?
So far i'm thinking getting through the firewall would probably be something akin to a Distributed Denial of Service (DDoS) Attack, and the malware might infect a file, and then cause a memory leak so that person slowly dies and then becomes a Zombie. but the inside simulation way of killing them, is some form of "Task Manager, End Process" gun... (that's not supposed to sound as stupid as it does)
Also for the sake of argument, lets say its not practical to "backup" an entire person maybe due to drive space, so once the person is dead, they cannot be restored from backups
Edit: as this is seeming too broad.
The part i'm struggling with the most in terms of computing is how a single piece of malware, would be unable to get through whatever defenses put before it, but multitudes of that same malware (no difference in base code) are able to overcome it this is how it would appear from the outside looking in, from the inside it would appear as the humans putting walls in the way.
