Final answer:
Before installing a software application, a support specialist should update antivirus definitions, install all available software, and not skip the installation guide.
Step-by-step explanation:
Before a support specialist installs a software application, he or she should update antivirus definitions. This is important because it helps ensure that the computer is protected against any potential threats that may be present in the software installation files. By updating antivirus definitions, the support specialist can identify and quarantine any malicious files or programs before they are installed.
In addition to updating antivirus definitions, it is also important for the support specialist to install all available software that is required for the proper functioning of the application. This includes any necessary updates or dependencies.
Skipping the installation guide is not recommended as it provides important instructions and information about the software installation process. Taking a coffee break may be tempting, but it is not a necessary step in the software installation process.
