the exploits on wearedevs page

i am some what new to this but ive used a couple different exploits for roblox but they havent been working recently. people have suggested i use the exploits krnl or coco z beacause they are known as the best free exploits but krnl hasn't been working at all so i tried to download coco z, i looked it up and i found it here on the wearedevs exploits page but when i download it the same thing happened just like other exploits on this page, instead of downloading what i see others downloading on there screens when i watch the tutorials it downloads this thing called "winzip" and when i open it a page opens up on my screen and theres an advertisement that takes up most of the screen and on the bottom theres 2 things small rectangles i can write in (i dont remember what it asked me to write but i think it was my name or something). please someone tell me how to download it or maybe i didnt go to the right dowloading site, anythings helps.
