Hi All, I have a Windows XP Virtual Machine with MalwareBytes Pro on it that I use for security research. When the Resident Shield is enabled on the VM, as soon as a file is displayed (not clicked, or accessed) in Explorer then the resident shield popup is displayed as shown in this example: However, when exactly the same Malware sample is presented to a machine running MalwareBtyes Pro on Windows 7, then the resident shield popup is not shown. You can even select the file in Explorer without any effect: If you right click the file, and select Properties then the resident shield does detect it. But until you actually do that (or attempt to start the program) as far as MalwareBytes does not detect it. Is this simply a difference in OS behaviour (Windows XP vs Windows 7) or is there something odd going on with the resident shield on Windows 7? Many Thanks, Ron
