1) Look at the persons level and if they have submissions or not. If not, it's going to give you a virus most likely. 2) Recently, a website called, "minecraftcodes.me", has taken people yo the website, given them 3 steps. Once they do the 3rd step, they have a virus/trojan on their PC. So dot go to that website and dont trust level 1 members with no submissions. 3) Downloading somethig like a Minecraft Code Generator, HAS or MOST LIKELY HAS a virus or trojan. Dont download them. 4) Diamonding this Tutorial will not get you viruses!
