Document Summary

Software that helps run the computer instructions between application software. Computer software that is designed to help the user perform single or multiple related tasks. Application software cannot run without the presence of system software. Check if anti-virus software is installed and whether it is the latest version. Also check for the expiry date of the software, as you will need to ensure that it is kept up to date. If virus protection software is not installed, you need to install it right way. Check if there is application software you need for school or work. This may or may not be preinstalled for you.
