  • SAFErating from user 3hlav for file C:\Windows\System32\smss.exe (Variant: 642542)

    This is the session manager subsystem, which is responsible for starting the user session. This process is initiated by the main system thread and is responsible for various activities, including launching the Winlogon and Win32 (Csrss.exe) processes, and setting system variables. After it has launched these processes, it waits for either Winlogon or Csrss to end. If this happens normally, the system shuts down; if it happens unexpectedly, Smss.exe causes the system to stop responding (hang). Please be careful, check MD5 hash, this MD5 hash: 9B08A8C6331C2DA9C30377BCB4262721 is secure. But there are viruses with same name, so if you see in your SystemExplorer two or more processes with that name, your PC probably is infected.
