There is an evil, isolationist group that wants to wipe out all the “Impure humans” living on planet earth and restart society with “genetically perfect humans”. This organization has developed a deadly virus that will kill all the humans on earth that aren’t inoculated against it, and allow this new superior master race to prosper. My question is, how could they spread this virus to the entire planet with minimal effort and time!

That cannot be achieved with your constrain of minimal effort and time.
If you really want to wipe out "all humanity but those inoculated", you will have to reach all the remote tribes hiding in the jungle and so far managed to stay away from western world diseases.
They don't have a social media account, so finding them will prove tricky and require large effort and resources.
Long incubation and than a fast killing last phase. Maybe triggered by some external stimulus so chaos breaks at once. It has time to spread before anyone notices it and than kills before anyone can develop countermeasures.
Animals, especially Birds also carry it but it is non-lethal to them.
Death of the host does not kill the virus, so the corpses keep spreading the virus.
Can stay inactive for a long time until a new host arrives
You´d still have to get to those remote island that are too far away for birds to reach - as well as any arctic expeditions etc. Maybe adding some spraying devices to planes, weather balloons or rockets will help get it in the upper atmosphere and slowly raining down.
Also think about who will organize safe shutdown of all those atomic reactors, chemical plants, oil rigs etc. or this evil group will probably have to live on a pretty damaged earth.
Ever played Plague Inc? ;)
On a serious note, here are a few points:
- You need your virus to be lethal to humans, but not anything else
- Your virus needs to be airborne, as this is the fastest method of travel
- Your virus needs to reproduce rapidly
- You need your virus to be in the lysogenic phase (Google it, but from what I can understand in my Biology GCSE lessons, this phase means that the virus will only be lethal after a certain stimulus is activated)
- Your virus could radioactively decay, so that its host dies of radiation, but I don't know if and how this is possible
Entire planet and minimal effort and time are in contrast, at least if you don't define how much is "minimal".
A way to spread the virus to the entire planet is to have a virus that is air-borne and so much of it that you can saturate the atmosphere, but this require a big effort and probably a lot of time. If the virus can reproduce at exponential rate, maybe you need less virus and less time.
This assuming that your virus has a long enough incubation period so you can spread over without any evident symptom and/or death or, on the other hand, that developing a vaccine/cure is a long enough process to replicate, otherwise it will be futile.
You also should start from the advanced country, (USA, Europe, China etc) since they are where the chances to develop a cure is higher, so you need to wipe them out first (the remote tribe in the Amazon forest is less a concern for this).
Rather than discuss the virus itself, thinking about the delivery method might be the easier strategy.
If one takes a page from 12 Monkeys, one of the most efficient methods is to release the virus in an airport, or several airports, and let the throngs of bustling people spread the contagion for you. Presuming air travel is as prevalent in this fictional world as it is here, you could get worldwide vectors in under a week.
If an inoculated person can still carry the virus, there's not even a need for test-tubes or anything. They just walk around breathing. Amble around to all the terminals, national and international, and away you go.
I think the best option would be water contamination, humans only drink fresh water, wish is 2.5–2.75% of the total water in the globe. plus animals only drink fresh water, meaning they can also get contaminated and since humans eat animals, that's another source of contamination for free basically. You want to make your virus with minimum effects and that it only kills after sometime, since then it would go unnoticed and when it started to kill, most of the people by then would already be infected so even if they tried to prevent it it would be too late.
