You can delete them via Hijackthis 'Delete an NT Service" doing it this way you first need to fix the service in Hijackthis so it is disabled, Hijackthis will not delete services that are still running.
Or, you can use sc.exe to stop and delete the services.
Using sc command to delete the service you would need to know the service name first .... what's listed in the Services when you run "Services.msc" are the Display names not the Service name...... so to get the Service name you would need to rightclick on the service > properties > and get the service name from there.
Once you know the service name, you can delete it using sc command below:
Go to Start Menu > Run > type
cmd
Press OK then type the commands onto the cmd screen pressing Enter after each line:
sc stop nameofservice
sc delete nameofservice
exit

open run -> services.msc and check the services you want to delete, you got the Settings of the services and if it's running, you stop it, in the settings window you will also see where it's located and then you just delete that file
