ccRegVfy.exe ist der "common client" von Symantec Corporation. (Norton AntiVirus)
how to remove popup when i start windows xp
Die ccregvfy.exe (Common Client Registry Integrity Verifier) gehört zu "Norton Anti Virus 2003." Sie überprüft die Vollständigkeit der, vom Virenscanner, gemachten Registryeinträge. Das ist gut und wichtig, denn sollte ein Hacker oder ein Virus die Einträge ändern, bemerkt es der Virenscanner nach dem nächsten Neustart, und kann, bei bedarf, die Registryeinträge die "Norton Anti Virus 2003" gemacht hat, wieder herstellen.

Best practices for resolving ccRegVfy issues

A clean and tidy computer is the key requirement for avoiding problems with ccRegVfy. 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.
