#Documentation

The user interacts with the expert system to determine the hazards that can affect their machine by answering a series of questions:

 - Validation of the entered password
 - Is the machine up to date?
 - Is an antivirus installed?
 - Is the firewall activated?
 - Has there been any interaction with an unknown website/program?

Regarding the obtained results:

 - The system informs the user about the identified risks.
 - The system also provides information about the security of their machine.
