This message keeps coming up whenever I try to launch Minecraft. I have no adware, I deleted it long ago. The main issue that I have is whenever I try to launch Minecraft, the ad folder in objects fails to download. So I manually created an ad folder and tried to download the file with the link that they gave me. This still doesn't work and this keeps popping up:
