Do not post links like you did, the link you posted was actually to an unsavoury site so I removed it. Malware Bytes is not an anti virus. It is antispyware and if it managed to remove the whole infection you are extremely lucky because these types of infections always seem to require deeper digging, hence people come here and run our tools, Malware Bytes is just one part of the process. As long as you think you are ok though....
