Malicious URL Help

Hi, my name is Sage and I need help! I play a game called Minecraft and (this just started today) when i click “Open Minecraft” Minecraft Launcher pops up (like normal), but also Malicious URL Blocked pops up. It says "Object: hxxp://pixel.quantserve.com/pixel/p-19UtqE8ngoZbm.gif Infection: URL:Mal Proc:Users/Sage/Desktop/Gaming/Minecraft.exe

It won’t let me play Minecraft and i’ve tried uninstalling Minecraft scanning my computer with avast! full system scan and Malwarebytes Anti-Malware scan. I can’t get rid of this thing popping up! PLEASE HELP ME!!!
