GMER is a useful application designed to help you detect rootkits, scanning basically every single part of the system to make sure you're on the safe side.
It is indeed intended to serve such an important job, but the way GMER does it is pretty remarkable.
While the interface is not at all eye-candy, but rather simple and well-organized, the application organizes all features in tabs, which means we got “Processes”, “Modules”, “Services”, “Files”, “Registry”, “Rootkit/Malware”, “Autostart” and “CMD”.
As you can see, you can monitor most sides of the computer, but the one that's the most important is the “Rootkit/Malware” screen that helps you keep your system secure.
There's a scanning system that checks the selected drive for dangerous files, so the app scans for hidden processes, threads, modules, services, files, Alternate Data Streams, registry keys, drivers hooking SSDT, IDT, IRP calls and inline hooks.
What's more, the application provides a very simple way to monitor loading drivers and new processes, libraries, file functions, registry entries and TCP/IP connections.
There's no configuration screen, which makes it even easier to use, but the lack of a comprehensive help file makes it more appropriate for experienced users who know how to handle all the aforementioned features.
GMER doesn't need a super computer to run properly, but instead it uses a moderate amount of resources to perform a scan, while being able to work on all Windows versions.
All in all, GMER make in come in handy to many users out there and with a few improvements in some areas, it could become a much more attractive product.
