What is the difference between MalwareBytes.exe and mbam-setup.exe? I have downloaded both of them and the first has 1,774,000 bytes and the latter has 5,738,016 bytes? I downloaded these after reading about the Antivirus 2009 problem as I have recently started getting Antivirus 2009 popups and saw that MalwareBytes.exe was recommended for clearing up the problem. I downloaded mbam-setup.exe and installed it before finding MalwareBytes.exe for download also. Is one a full install and the other a standalone executable? Do they both do the same? If not, which is recommended? I searched for differences on this site, but could not find any threads which looked like an answer. Thanks in advance for any feedback.
