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.

Best practices for resolving SCardSvr issues

A clean and tidy computer is the key requirement for avoiding problems with SCardSvr. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic 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 resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the SCardSvr.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries.
