Learn about Windows® Firewall configuration
What is Windows Firewall and how is it useful? What kinds of problems may be encountered while configuring firewall on Windows operating system?
Windows Firewall is a program that provides protection to the system from malicious software such as worms. It blocks the dangerous software trying to find a way to connect to your computer. This Windows firewall blocks the virus and worms from reaching your computer, but it might not detect or disable the virus if it infects your system. A firewall helps to monitor all incoming and outgoing network traffic and might be configured to block certain types of data. It would block the connections to the programs which are not in the list of allowed programs and it would allow you to configure the settings of each network separately. Firewall in Windows allows checking the information which is from the network and depending upon the firewall settings it would block or allow the data to pass via computer. If your antivirus program has the firewall then you need to turn off the Windows firewall in your system.
The following are the problems that may occur while configuring firewall on Windows Operating System:
- Benefit of Windows Firewall
- Conflict of firewalls
- Virus attack
Benefit of Windows Firewall
Firewalls are customizable and using Windows firewall you could make the computer more secure. Windows Firewall is capable of blocking a program or a service if that program does not respond to a client's request or the client programs do not receive data from the server. For safe Internet surfing you need to install the firewall.
Conflict of firewalls
Firewall is a separate software package, and after installing you need to configure the firewall. If there is another firewall already installed in your system, it might cause conflict between the firewalls. If the firewall setting is not properly installed in your system, it might cause trouble while configuring Windows Firewall.
If your system is infected with harmful virus, then it would interrupt the configuration of Windows Firewall. These viruses corrupt the system files and prevent the configuration of the system. Viruses commonly affect the registry and may severely damage the necessary files stored in it. Malicious viruses have the capability to delete or corrupt the installation file and thus you might not be able to configure the Windows firewall.
