MSoft's verifier.exe shows that this is an unsigned driver. I did not explicitly install it myself, nor knowingly allow it to be installed. It is disgusting that a vendor such as Samsung installed this on my PC behind my back.
Ist nur für Netzwerk-Drucker / Serial-Port (heute kaum noch anzutreffen) Ich drucke, scanne (und kopiere:-) seit Jahren ohne diesen Treiber. Eigentlich auch nur, weil den Enwicklern ein Fehler unterlaufen ist: im entspr. Abschnit der Reg. steht \?? \C:\WINDOWS\system32\Drivers\SSPORT.sys statt (Richtig wäre) %SystemRoot%\system32\Drivers\SSPORT.sys oder auch: C:\WINDOWS\system32\Drivers\SSPORT.sys ( bei den meisten PC, wo auf dem 1. LW installiert ist )

Best practices for resolving SSPORT issues

A clean and tidy computer is the key requirement for avoiding problems with SSPORT. 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.
