Problem Description:
Firewall is different than an Antivirus Software such as Microsoft Security Essentials. A Firewall is a software or hardware that checks information coming from the Internet or a network, and then either blocks it or allows it to pass through to your computer, depending on your firewall settings. To help protect your computer, you need both a firewall and an antivirus and anti-malware program.
Affected Products:
Windows XP, Vista, Windows 7, and Windows 8, Windows 8.1 and other versions of Windows.
Cause of the Problem:
  • Not Applicable.
Instructions for Setting up Windows Firewall :
Step 1 :Opening Windows Firewall
  1. Windows Firewall is preinstalled with your computer. Unlike other Microsoft free tools such as Microsoft Security Essentials or Safety Scanner you do not need to download and install it.
  2. To enable and configure it, you simply, Open Windows Firewall by clicking the Start button Picture of the Start button, and then clicking Control Panel. In the search box, type firewall, and then click Windows Firewall.
  3. In the left pane, click Turn Windows Firewall on or off. Administrator permission required If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
Step 2 : Turn On Windows Firewall
  1. Windows Firewall is on by default. And when the Firewall is turned on, most programs are blocked from communicating through the firewall.
  2. If you want to allow a program to communicate through the firewall, you can add it to the list of allowed programs. For example, you might not be able to send an instant message until you add the instant messaging program to the list of allowed programs.
  3. To add a program to the list, see Allow a program to communicate through Windows Firewall.
Step 3 : Block all incoming connections
  1. Windows Firewall can be configured to block ALL all incoming connections, including those in the list of allowed programs.
  2. This setting blocks all unsolicited attempts to connect to your computer. This setting is ideal when you need maximum protection, such as when you connect to a public network in a hotel or airport.. With this setting, you aren't notified when Windows Firewall blocks programs, and programs in the list of allowed programs are ignored.
  3. When you block all incoming connections, you can still view most webpages, send and receive e-mail, and send and receive instant messages.
Step 4 : Getting Notified by Firewall
  1. The Notify me option is so that you are given an alert, when Windows Firewall blocks a new program.
  2. If you select this check box, Windows Firewall will inform you when it blocks a new program and give you the option of unblocking that program.
  3. It's a useful setting to make sure that you are inadvertently not blocking a useful program leading to unnecessary problems.
If above steps did not help fix your problem, you need assistance from a certified technician. Please call GuruAid at 0800 031 4181.
