Today I have a firewall rule allowing incoming traffic for a program called kmss.exe in Windows Firewall on one of my computers and I'm 100% sure that I didn't add it, neither was I ever asked to allow that program to connect to the internet through Windows Firewall.
So, the firewall rule says that the program must be in C:/Windows/Temp/Files/Bin/kmss.exe but when I opened C:/Windows/Temp/ in file explorer, there was no directory named "Files". I tried to use command prompt to find it, I failed again. And my settings already allow for hidden folders to be shown in file explorer.
So, I suspect that C:/Windows/Temp/Files/Bin/kmss.exe does exist, but somehow it has managed to modify or fool Windows into thinking that it does not. Is that possible? If yes, what can I do to access that file and remove it?
