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.
