A firewall is used in Windows operating systems and is a software package that checks data and files entering over a network for threats. A firewall can also block malicious software from unknown sources from running.
Enabling firewall
Open the "Start" menu and left-click once on the "Control Panel" line in the list on the right. A panel with settings for various computer parameters will open.
The control panel can also be launched through the "Computer" folder. To do this, double-click the left mouse button on the "Computer" shortcut on the desktop and in the upper part of the window that opens, click the "Open Control Panel" button.
In the upper right corner of the window, expand the list next to the "View" line and select the "Small icons" type. A list of settings for various parameters of the personal computer and operating system will be displayed.
In the list that opens, find the line "Windows Firewall" and click on it once with the left mouse button. The firewall management area opens, containing functions for enabling and disabling security systems, changing the exclusion list, navigating to help files for the firewall, and more.
In the list of options on the left, select the line "Turn Windows Firewall on or off." The firewall settings area for each type of network connection (home and public) will appear on the right.
In the settings area, mark the required fields with a dot. Turning on Windows Firewall for Home Network protects the user's computer from malicious files and programs transmitted within the workgroup. Activating a public network firewall protects your computer while you have an active Internet connection.
General recommendations
When enabled, Windows Firewall can automatically block user programs. To remove the blockage, you need to add the trusted software to the firewall exceptions list.
If you have a permanently active Internet connection, the user is advised not to turn off the firewall functions that block malicious files and software.
If antivirus software is installed on your computer, it is recommended to disable Windows Firewall to avoid conflicts between them and, as a rule, incorrect operation of both security programs.
With Windows Firewall notifications enabled, when a malicious or suspicious program attempts to launch, the system will prompt the user to allow or block the application. When the notification system is turned off, the firewall will automatically block the launch of suspicious applications.
