I cant log on Win XP SP2 after install Norton Antivirus 2007 .I only can log on safe mode (no Last Known Good ,because i've turn off system restore) .I've remove NAV 2007 then log on Windows easily .I've reinstalled NAV 07 again ,but it've liked that again .Off course the cause is NAV 07 ,but how can install NAV 07 and log on Windows normal ?Is there anybody been like me ?
