I found out about scardsvr.exe because it was using 98% of my CPU. I found that pulling and re-inserting the smart card resolved the problem.
Windows smart card service, it is a standard component of the OS, it is required if you have any program that uses PC/SC smart card readers or tokens (the system talks to the hardware via this service). You can disable it, but those programs won't work correctly.
