Mebload.AR is introduced as a Trojan infection which was designed to attack specific operating systems. As we all can see it was detected by antivirus and had a serious impact on it. Antivirus fails to handle it because it is controlled by a remote hacker who can put such infection scattering all around system corner. It can act as frivolous stones and it is difficult to wipe out all of the infections from the program files, processes, dll files and registry entries. It will run a few other additional jobs on computer again which may expend a large number of resources.
