FB 1.5.0.4306

Firebird is running as ServiceApplication and I try to stop it from Control Panel.
I pushed Stop button everything seems OK.
I close the Control Panel Applet
and run again control panel applet
it says "Firebird is running as an application"
I checked the Task manager
there is fbserver.exe and fbguard.exe in process list.
It is impossible to END PROCESS them

Also in Control Panel Applet when I push the STOP button it says nothing
when I try to change it "as a service" again it raises an ERROR
"Error Code 1060 raised in Getserver..."
The sepecified service does not exist as an installed service.

How can I stop firebird?

Regards,
