What is GCS.exe?

The genuine GCS.exe file is a software component of Gnab by Empolis GmbH.
GCS.exe is an executable file that has been reported to be an executable file created by a trojan, a malicious computer program designed for the Windows platform. Trojan worms can remotely execute programs and run commands, use a keylogger to track keyboard entries, send data across networks and spread copies of itself. Trojans are known to steal user passwords and personal data by allowing hackers access to the computer. If you find yourself a victim of identity theft, please follow these steps: Inform your bank or financial institution that you are a victim of identity theft so that they may monitor your accounts or change and/or change your account numbers. Change all stolen passwords only from a clean computer. Changing passwords from the same infected computer may not be an effective solution as the new password will likely be stolen again. Use a dedicated anti-virus or anti-malware software to scan and clean the infected computer. Empolis Information Management GmbH is a German software company that specializes in content management and knowledge management. The company was founded in 1986 as EPS Bertelsmann, as a subsidiary of MohnDruck GmbH in Guetersloh, Germany and developed printers. It was renamed to Empolis in 2000.

Best practices for resolving GCS issues

A clean and tidy computer is the key requirement for avoiding problems with GCS. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the GCS.exe process on your computer, the following programs have proven to be helpful: ASecurity Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan.
