Cant Remove Rootkits any help?

Scanning my PC for rootkits using AVG rootkit scan i found acouple of infected areas that cant be removed or healed. I need help to know if it is possible to remove the rootkits manually and if they are of any harm to my PC currently. And i already tried Malwarebytes in safe mode and detected nothing.

 

The results where :

 

"C:\PROGRA~2\Symantec\DEFINI~1\VIRUSD~1\20090110.020\NAVENG.SYS";"Hidden driver";"Object is hidden"
"C:\PROGRA~2\Symantec\DEFINI~1\VIRUSD~1\20090110.020\NAVEX15.SYS";"Hidden driver";"Object is hidden"
