Chkdsk (check my disk) ist ein altes DOS-Programm, das noch immer und vorzüglich verwendet wird, um die Festplatte auf Fehler zu überprüfen und diese zu beheben. Getarnte Viren als chkdsk.exe sind Unfug.
Chkdsk (Chkdsk.exe) is a command-line tool that checks volumes for problems. The tool then tries to repair any that it finds.

Best practices for resolving chkdsk issues

A clean and tidy computer is the key requirement for avoiding problems with chkdsk. 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. This allows you to repair the operating system without losing data.
