hi,
your system still hosts some incompatible softwares (or, better, components of):
Filename C:\Program Files\Common Files\Symantec Shared\VirusDefs\20081002.024\NAVENG.SYS - Symantec Antivirus Engine
Filename C:\Program Files\Common Files\Symantec Shared\VirusDefs\20081002.024\NAVEX15.SYS - Symantec Antivirus Engine
So, pls remove them and KAV; clean your system with Ccleaner (or similar) and try to install KAV once again (maybe it would be enough to remove incompatible softwares only...

...).

I have removed them and KAV, and reinstall KAV from KAV admin kit share folder. However, during install KAV, error 'AVP.exe can not read/write' is appeared. And then restart the computer, the error is shown as attached file.
