Very Slow Boot and multiple smss.exe

[gregor4005]

Hey Guys!
I recently got the problem where my PC boots about 3-5 min to the login screen.
I did a performance analysis where I can see that multiple smss.exe processes are running and one of them takes about 100 seconds of the boot time.
I added a download link of the performance analysis (the 7z-file is 198.5 MB and the extracted file is ~5GB):

I dont know how to get rid of the second smss.exe process and I don't know what this process is actually doing.

The System I am talking about is a Windows 7 Professional x64 installation.
Components:
MSI X99A SLI Plus
Intel Xeon E5-1620 v3
Corsair Vengeance LPX schwarz DIMM Kit 16GB, DDR4-2666
Gigabyte GeForce GTX 960 WindForce 2X OC, 4GB GDDR5
Samsung SSD 850 EVO 500GB

I hope someone can help me

hrmm... I'd be a bit careful here as we could be dealing with malware, first run a scan with your antivirus and see what happens. also, where is the secind one located? smss.exe should be in C:/Windows/System32, if the second one is anywhere else on your PC, you've got a virus.
