What is chkdsk.exe?

The genuine chkdsk.exe file is a software component of Check Disk Utility by Microsoft.
"chkdsk.exe" is the main executable for the Check Disk Utility, which is part of Microsoft Windows Operating Systems. The file is responsible for launching the program and running the file integrity scans. It also loads the DOS prompt because it is needed for the program to operate, since the utility is a DOS application. The file is basically a command line tool that ensures that your volume is not corrupted and that the file system is healthy. Because it is a command line tool, it responds to user commands. By default, it scans as "read only" if the user has not instructed it to fix any errors through command line parameters. Microsoft has developed innovative technology since they started in 1975 with their BASIC interpreters. Their Windows Operating Systems have become a standard and they also paved the way for the future of networking infrastructures, innovative devices, and applications to fit everyday life.

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 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 repairing of your installation or, for Windows 8 and later versions, 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 chkdsk.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. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
