Steam.exe lief in C/Programme/Steam/Steam.exe, SteamService lief in Gemeinsame Dokumente ist denk mal ein Trojaner.
Die steamservice exe wird für Steam gebraucht... sie ist wichtig für Steam aber nicht gefährlich.

Contains a Trojan gen as far as AVAST told me.
Completely harmless. It is an important component of Steam, which is a trusted online game service provider and DRM. Valve, the creator of Steam, is completely legitimate. If any software says this is a virus, it's a false positive.
SteamService is necessary to run certain games such as Skyrim. It is not necessary to run if you are not running those games. Simply turn it off.

Best practices for resolving SteamService issues

A clean and tidy computer is the key requirement for avoiding problems with SteamService. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic 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 resmon 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 DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the SteamService.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries.
