Fig 1: a screenshot from a software application. Utility software is software such as anti-virus software, firewalls, disk defragmenters and so on which helps to maintain and protect the computer system but does not directly interface with the hardware.
If the operating system is the only software installed on the computer, then the computer can be powered on yet nothing can be done with it. This type of software is called system software. Application software, such as Firefox, are the programs that actually do anything useful to the end user.
