The primary characteristic that makes the virus featured in the Viral mod so tedious is the fact that it actually ends up buffing mobs that are supposed to be hostile to players while simultaneously damaging animals that don’t do any harm to the player. The mod doesn’t really add any actual new functionality to Minecraft but it does manage to make things a lot more difficult for the players and it does so by adding a special kind of Virus to the game named ‘Viral’ and this virus spreads from mobs to mob and is definitely going to make things a lot more tedious for you as you journey through the Minecraft world. The only reason you’d ever want to use a mod like Viral is if you feel that the world of Minecraft isn’t challenging enough by itself and you want to make things a little bit more interesting.
