Norman Sinowal Cleaner

Norman Sinowal Cleaner is a lightweight and portable program that removes the SinowalMBR rootkit from the computer, as the name implies. It packs limited options that can be configured even by less skilled users.
As there is not setup pack included, you can simply drop the executable on any directory of the hard drive and run it. Otherwise, Norman Sinowal Cleaner can be moved to a USB flash disk or similar storage unit, from where you can run it on any computer.
What sets apart portable apps from installers is that no entries are added to the Windows Registry, thus minimizing the risk of system errors. Furthermore, leftover files are not kept on the hard drive after utility removal.
The interface is represented by a standard window with a plain layout and no uncommon options. You can include multiple areas in the scan procedure, which can be either directories or entire drives (whether they are local or removable).
Once the scanning procedure is done, you can check out log details in the main frame, which focus on the total found files, unpacked archives, scanned and not scanned files, infected and repaired/deleted files, as well as removed infections and the total scanning time.
The app is very forgiving concerning the CPU and system memory. It has a good response time and may take a while to complete a scan job, depending on the size of your scan areas. However, no error dialogs have been shown in our tests and the tool did not freeze or crash. Aside from the fact that no recent updates have been made, Norman Sinowal Cleaner provides a straightforward solution to removing the SinowalMBR rootkit from infected workstations.
