Hallo,
anbei meine logfile.
Angeblich soll
O20 - Winlogon Notify: NavLogon - C:\WINDOWS\System32\NavLogon.dll
kritisch sein. Antivirus, spybot und adaware zeigen jedoch nichts.
Soll ich den Eintrag über HijackThis trotzdem fixen, oder gleich aus der registry löschen ?

Danke für einen Hinweis !!!!!!!!!
