    try also Windows Optimum

    Windows Optimum is a tool for

    •Stop any type of program or service in your system.
    •Remove keys or values from of started applications in the registry or other parameters.
    •Delete keys and values in the registry even if access is not permitted, even if you're not the administrator.
    •Remove any file in your computer, even the file is in use. If the file deletion is impossible, the file will be deleted when you restart the system even if Windows Optimum is not running.
    •Cancel, or establish restrictions on Windows' Policies.
    •Manage Windows Services.

    Efim,

    this is a Google question. SMSS.exe is a Windows process called Session Manager SubSystem. More information here: http://www.tech-faq.com/smss-exe.html

    If the file is located anywhere other than the C:WindowsSystem32 folder, then it might be malware.
