Where are the firewall and antivirus software settings located? Firewall is blocking the connection

IN general case A firewall (aka firewall) is a specialized hardware and software complex that allows you to minimize the possibility of harmful influence from the outside on the section of the network entrusted to it.

Of course, more reliable protection is provided by firewalls in the form of separate modules, which are usually located in the server room and are very solid equipment.

However, such complexes cost several thousand dollars and “mere mortals” (including most system administrators) make do with ready-made software solutions such as Windows 7 Firewall.

Essentially, the firewall performs the functions of a checkpoint on or where it is installed.

Which packet to skip and which to block? Brandmauer determines with the help of rules laid down in it in advance. These rules vary depending on the software version, and users can also customize their rules during operation.

The need to create your own rules for the firewall arises provided that the firewall is enabled, but special permissions are required for some programs (primarily for incoming traffic). Restrictions may also be placed on outgoing traffic.

The technique of working with the “on-board” firewall does not change much from version to version. Windows versions. So…

How to enable Windows 7 firewall.

Let's look at how to connect and configure an internal firewall yourself

  1. 1. How to access the Windows 7 firewall?

Click on the "Start" key and select "Control Panel" from the programs menu on the right.

After this, the Control Panel window will appear, where you should select “Windows Firewall”

The firewall settings window will appear. If the firewall is disabled, it will look something like this.

On the right is a list of settings and networks active on this moment.

On the left you can see the firewall settings items.

  1. 2. How to start the Windows 7 firewall?

To enable the firewall, select “Turn Windows Firewall on or off.”

In the next window, select “Enable…” for the desired networks and set the appropriate checkboxes, then press “Enter” (or the “OK” soft button).

  1. 3. Where is the firewall on Windows 7?

If the Firewall was accidentally disabled and the security alert settings were not changed, then you can find it much easier. A checkbox will appear in the desktop panel on the right; clicking on it will open a menu that looks like this:

In this case, to enable the firewall, just select the appropriate item.

Now your firewall on windows 7 is enabled and the settings window looks like this:


How
configure windows 7 firewall?

Setting up a firewall on Windows 7 involves setting up appropriate rules for it.

It is advisable to immediately create an exclusion rule for .

How to add a program to windows 7 firewall exceptions?

To do this, select the first item in the left menu - “Allow the program to run...”, after which the settings window will appear:

In the following list you should find the necessary program, which you want to add to the windows 7 firewall exceptions. In this case, it is MsSE, which is free antivirus and within the framework copes with its responsibilities perfectly.

If necessary, check or uncheck the appropriate boxes and click OK.

The Firewall general settings window will appear again.

To fine-tune the firewall on Windows 7, select the “Advanced Settings” menu item, where all the rules for all connections are spelled out in detail. It is not recommended to configure advanced settings without proper experience. In this area, you can enter rules manually.

Let's look at an example:

In the right column, select "Outbound Rules."

The middle column will display all available rules for incoming connections.

In the left column, find the “create rule” item and click on it.

The rule settings window will appear.

On the left are the “steps” that need to be completed, on the right are the settings options.

To configure rules for a specific program, click “next”.

In the next window, you will need to select the required program if the rule does not apply to all applications installed on the computer.

In the “actions” window, we should indicate whether we allow or deny the connection in this rule, and also configure additional conditions (encryption, encapsulation).

The next step “Profile” predetermines under which network profile this rule will work.

The last step is Name.

Click on the “Finish” button and the new rule will be added to the firewall settings on your computer.

If the Internet does not work and there is no way to call a specialist urgently, you can try to adjust the settings yourself using our article.

Advice: before looking for methods to solve problems in the network and router settings, check the status of your account with the provider and the security of the network cable; in approximately half of the cases this solves the problem.

Firewall or antivirus?

Sometimes, Internet access can be blocked by the system's own security agents, such as a firewall or antivirus. Define ban Windows Firewall 8 is quite simple - disable it in the system settings and check the connection; if the network appears, the problem has been detected.

If the ban comes from the antivirus, you need to disable the program itself or end the corresponding processes through the task manager.

Setting up Firewall in Windows OS

The main function of a firewall is to check data coming from the Internet and block those that cause concern. There are two modes: “white” and “black” list. White - block everything except what is allowed, black - allow everything except what is prohibited. Even after full customization The firewall still needs to set permissions for new applications.

To find the firewall:


If you already have an antivirus installed, disable the firewall as shown in this picture.

Blocking outgoing connections

The firewall and sometimes antivirus can completely block all outgoing connections.

To block outgoing connections with a firewall in white filter mode, you need to:

  • go to the “advanced settings” of the firewall;
  • open the “Properties” window;
  • set “outgoing connections” to “block” mode in private and public profiles.

Application Rules

There is a special list of programs that are allowed to exchange data with the Internet, and if the one you need is blocked, you just need to configure permissions for it in this list. You can also set up notifications so that if a new application is blocked, you have the choice to leave everything as is and allow access to that program.

For example, you can block Internet access for Skype or Google Chrome, or vice versa, leave access only for a couple of specific work programs.

Service Rules

To configure access for services:

  1. go to the advanced firewall settings;
  2. on the left select incoming or outgoing rules;
  3. On the right, select “Create a rule”;
  4. Select “Custom” from the list;
  5. enter the service name or select it from the list provided.

Newer versions of Windows, starting with Vista, provide the ability to select a service from a list without manually entering the service name. If you do not have access to a computer in windows networks xp or windows server, you need to configure the access policy service, then detailed description can be found in the system help.

Activate the reserved rule

To activate a reserved rule, you need to repeat steps 1-3 from the previous section, then:


Allow VPN connection

To set a special permission VPN connections, you need to repeat steps 1-3 again, then:


Setting up an antivirus

If problems arise, one of best options– go to the antivirus website or contact product technical support, they will tell you exactly correct settings programs.

An antivirus should not block working programs - like Google Chrome or Skype, but should check them while working.

Safe antivirus settings should include:


Update

The antivirus update must be current, either with the release of new versions, or monthly automatically.

No network access in Windows 7

If when connecting you see " Unidentified network", but all the settings are in order, contact your provider first - this may be an internal error.

After Windows reinstallation Internet settings usually return to their original settings, so you need to set them again:


The problem may be caused by errors Windows protocol To fix this, you need to reset the protocol settings.

It's pretty simple:

  • run command line with administrator rights;
  • enter and activate the command netsh int ip reset resetlog.txt;
  • reboot the laptop.

Is the problem with the router or the laptop?

When WiFi connectivity issues occur, you need to determine where the problem is coming from. This could be a laptop, router or ISP. If all devices connect to the router and work normally with the Internet, the reason is in the laptop; if, on the contrary, you connect network cable to the laptop and the Internet will work - you need to set up the router settings. When all else fails, contact your provider's technical support.

The reason is the laptop

If the problem is in the laptop, but all of the above settings are in order, diagnose the system for viruses and device operation. Possible operational problems network driver or even disruptions directly network card, connector.

May not match WiFi password dots, for example due to incorrect layout or CapsLock.

The reason is the Wi-Fi router

Router at incorrect settings can distribute WiFi without access to the network. Read on to learn how to properly configure your router.

One of the reasons for connecting without a network may be to protect the Wi-Fi network from unauthorized access by blocking it by MAC address. You can find out how to fix this problem on the router manufacturer’s website, or you can independently find the list of allowed or prohibited addresses in the settings and add/remove the address of your laptop.

You can view the MAC address of your laptop by entering the Ipconfig / all command in the command line.
Also, the router has speed limit settings for each client, so you can either allow the maximum speed or limit it to a couple of kb/sec.

Problems with Internet speed may be a signal for help from the router itself - perhaps you have not removed the factory film from it, it is covered with something or is overheating for other reasons. If you do not provide the device with normal ventilation, it will not last long and will be extremely ineffective.

Checking the Internet connection without a router

If you suspect the router is causing the problems, you need to connect the network cable to your laptop or computer to check. If the Internet does not work automatically, create a new one cable connection, enter the login and password provided by the provider. You may need to enter additional settings protocols in the adapter properties.

Setting up an Internet connection

To check whether your computer's IPv4 settings match those stated by your provider, you need to do the following:


  • check the IPv4 address and gateway, they must match those provided by the provider during registration.

Setting up a connection through a router occurs through the device’s web interface. The router sometimes comes with a settings disk, but you can do without it. For initial setup, it is best to connect the router directly to the laptop, and then to the Internet cable; connecting to the power supply is done last.


If you don’t have enough time to wait for a specialist, you don’t want to spend money, you feel like a confident PC user, then using various instructions and recommendations, you can try setting up your Internet connection yourself. Most likely, it will take two to three times more time and energy than contacting a specialist, but it will provide useful experience in the future.

The Windows Firewall (aka firewall) is responsible for the security of the operating system and protects it from external malicious attacks. To effectively protect their computer, every user must know how to work with a firewall and what alternatives can be used.

Do you need a Windows 10 firewall?

Of course it is needed. Here simplest example: V latest versions Windows (starting from 7) shared device management in one local network. It is thanks to this that in offices several computers can have access to the same printer or any other device. When you disconnect your PC from the network, you don’t even think about the danger that an “unsafe disconnection” might pose. The fact is that attackers can easily connect to a computer in order to realize their dirty intentions. It is worth mentioning that they cannot, but they could. They could if the firewall was not built into the system. The firewall does not allow “dangerous” incoming and outgoing traffic to pass through and blocks suspicious activity, which helps keep you and your device safe.

Why does it block apps?

The firewall blocks programs because it already has a built-in “moral code” - a set of rules, the violation of which prevents a data packet from being downloaded to the computer. These rules can be changed at your discretion. If you want, block all connections to your device; if you want, block access to the Internet for a specific program if it causes mistrust. Blocking various resources helps make your online experience safer.

How secure is the Windows 10 firewall?

The built-in firewall performs the same functions as downloadable antiviruses. Unlike them, it sends notifications much less frequently, has no advertising and does not require paid activation. The firewall runs continuously in the background and cannot be disabled without your command. Therefore, you can rely on it without resorting to additional software. If an application needs access to certain parameters of your computer, a request will come from the firewall, which you will have to confirm.

The firewall requests user confirmation to continue running the program

How to set up a firewall

The firewall can be configured in several ways.

How to open a port in Windows 10 Firewall

  1. Go to the Start menu, there we will need the Control Panel.

    Open the Control Panel

  2. Click on “System and Security” and click on “Firewall”.

    Open Windows Firewall

  3. In the firewall menu we find Advanced options.

    Select Additional options

  4. Select Rule for incoming connection and add the necessary ports.

    Create a new rule for incoming connections

  5. Click “Next” and enter SQL Server in the “Type” line.

    Selecting the rule type

  6. We indicate the TCP port and the ports we need.

    We indicate the necessary information. In our case it will be port 433

  7. Select the desired action. For us it will be “Allow connection”.

    Select “Allow connection”

  8. In the “Name” line, enter our port number.

    To complete the setup, call our port by its number

How to block an application/game in a firewall

To block an application in the Windows Firewall or, in other words, prevent it from accessing the Internet, you must follow these steps:

  1. Select the “Advanced Settings” section in the firewall menu.
  2. Click on “Outgoing connection rules” and click “Create rule”

    Create a new rule for the application

  3. Next, select the rule type “For program”.

    Since we need to exclude the program, we select the appropriate rule type

  4. Next, the system prompts you to select the program path. Click the “Browse” button and find required file programs.

    Leave all the boxes in place

  5. And at the end, we designate the name of the blocked program in a convenient way and click “Finish”. From this moment on, Internet access for the application will be blocked.

Firewall Update

Updating a firewall is a controversial and rather negative thing. The point is that there are no important functions it doesn’t carry much, but it often takes a considerable amount of time. Therefore, some people prefer to disable firewall auto-update.


The Firewall control application is one of the auxiliary programs and is responsible for data security and protects against leakage of this data to the network. The program controls the operation of ports and allows you to choose under what conditions applications will connect to the network.

The program interface is simple and concise

Currently, many antivirus solutions come with a firewall. When installed, the firewall built into Windows is disabled to avoid conflicts. There are also antiviruses without a built-in firewall, for example Microsoft Security Essentials. When installing it, it is desirable to have a built-in firewall or one installed separately from a third-party company. By default, Firewall in Windows 7 is enabled and configured universally. This is suitable for most users, as are all installed solutions. Here, together we will figure out how we can increase the security of our computers by indicating which traffic to allow and which not.

To manage the firewall, you must open it. To open it you need to find it. Use Windows 7 search. Open the Start menu and write “bra” and select simple Windows Firewall.

On the left side of the window, select Turn Windows Firewall on or off.

In the window that opens, you can disable or enable the firewall for the network you have selected or for all at once.

If you know the program and need to give it access, then check the boxes on which networks to allow communication and click Allow access. By default, the checkbox is in the network you are currently on.

Afterwards, you need to turn off the Windows Firewall service. Let's use the search from the Start menu.

In the window that opens, go to the Services tab and look for Windows Firewall. Uncheck the box and click OK.

In the window that opens, you can allow the program to connect through the firewall on the corresponding network.

If the program you need is not available, then using the Allow another program... button you can easily add it.

It is not possible to block any program from accessing the Internet here. (At least it didn’t work for me. I unchecked the µTorrent program and it still downloads).

In the window for allowing programs, you can experiment and not worry that the browser will not have access to the Internet (my case). Everything can be returned back using the Restore Defaults function.

By default everything should work fine.

Blocking outgoing traffic

If we want to achieve greater security, then one of the possible options would be to block outgoing traffic completely and set permissions for the programs and services we need. It should be noted here that an outgoing connection is considered to be one that was initiated by a program on your computer. That is, if your browser requests any page on the Internet and this page is sent to your computer, this is an outgoing connection.

To do this, select Advanced settings in the Firewall window.

In order to block all outgoing connections, you need to select Windows Firewall with Advanced Security in the left column and click Properties in the right column.

In the window that opens, go to the settings tab the desired network(public network - general profile, home network - private profile). In the Outgoing connections section, select Block from the drop-down menu. Click OK or Apply.

For greater security, you can block outgoing connections on both networks.

Permission for programs

After blocking outgoing connections, we need to give Internet access to the programs we use. For example, the Google Chrome browser. To do this, go to Rules for outgoing connections on the left side and in the Actions column on the right click Create rule...

In the wizard that opens, select For program. Click Next >

Specify the path to the program:

%SystemRoot%\System32\svchost.exe

since the update is performed under this process. In the Services section, click Configure...

In the window that opens, select Apply to a service and select Windows Update in the list (short name - wuauserv). Click OK.

To learn everything about firewall settings, you need to understand its functions and purposes. Let’s try to define the concepts of “firewall” and “firewall”, whether they have differences and similarities. Let's look at accessing the network and setting up servers.

What is this?

Before you do short review on a firewall, you need to know what a firewall is. This is a conditional program that refers to computer network. It works with network traffic monitoring and filtering. For this purpose, there is a certain set of rules in the hardware and software.

It is the firewall that is this firewall. The word is translated from German as “fire wall.” Often users cannot differentiate between a firewall and a firewall. This is not surprising, since both the first and second are firewalls. The only difference is that firewall is a German term and firewall is an English term.

Windows version

Starting with the version of Windows XP, the developer has implemented a firewall into the operating system. This is how the firewall settings became available. This does not mean that a similar software element did not exist before. A version of Internet Connection Firewall was previously released. But the main advantage of the new product was the presence of control over program access to the network.

Danger

The old firewall was part of the computer system, but was disabled by default due to compatibility issues. The settings for this firewall were available in network configurations, which meant they were difficult for some users to access. There have been a number of attacks since 2003 computer worms. This was due to a system vulnerability.

In 2004, attacks continued, leading to lightning-fast infections of the system. To fix this, the firewall needed to be modified. This is how Windows Firewall became popular.

New

A security log was built into the new firewall, which collected data on IP addresses and connections across home and business networks, as well as on the Internet. This service has hardly been updated since its release. Therefore, all settings of any parameters are suitable as for the old ones operating systems, and for new versions.

Now the firewall settings can be made in the Security Center, since this firewall is part of it.

Enable/disable

To make firewall access settings, you need to understand how to enable or disable it. Of course, it is not recommended to disable it, as this will compromise the security of the system. But sometimes disabling is necessary in order to activate the antivirus program.

Most of these programs have a built-in firewall. To avoid compatibility conflicts, the built-in firewall is disabled. If the downloaded antivirus does not have a firewall, then you can leave the Windows version.

To start working with this software and hardware element of the Network, you need to open it. As usual, there are several ways. You can simply enter its name in the search bar of the system. You will have a list of several options. It is better to select "Windows Firewall".

Another option for approaching this service is to go through the “Control Panel”. To do this, click “Start”, find “Control Panel” in the right column, and a window will open. Look at the right one top corner, where there is a line “View” and select “ Large icons" A list will appear in front of you, in which you will find a proprietary firewall.

A new window will open where you can make firewall settings. In the left column there will be a line “Disable or enable firewall”. There is a choice for home network and public. It’s easy to turn off notifications about app blocking right away. You must check the box so that the program will immediately notify you about the malicious utility.

Access blocking

Some problems with accessing the Network are related specifically to the firewall. Perhaps you did not understand how the antivirus program works and have denied access to the network. You can restore it in the firewall settings. Again in the left column, go to the line “allow a program or component to run through a firewall.”

A new window will open in front of you. It will contain a list of programs that have been blocked or allowed access to the Network. You just need to check the boxes where necessary. For example, here you can find a browser that does not go to sites and give it permission to do so.

If you need to allow access to the Network in your firewall settings for a program that is not listed, it is not difficult to do so. It is enough to find the “Allow another program” button under the sign that contains utilities. After which an additional list of applications will appear from which you can add another browser or software that needs access to the Network.

Remember that the more such allowed programs in the firewall, the less secure your work becomes. Ports that are opened are no longer controlled by the system and can allow malicious utilities to pass through.

Advanced

To provide more options for configuring access, you can use additional parameters. In this line you can adjust network profiles. There are three default options:

  • Domain Profile is an option for PCs joined to a domain.
  • Private - needed as a “bridge” to a private Network, it can be like home connection, and working.
  • General - needed to connect to the public Network.

Here you can work with connection rules different types. You may need to configure the server. The firewall easily handles incoming or outgoing connections. To do this, in the additional parameters you need to select the desired item and click on it, selecting “Create rule”.

A special window will open with several steps. Each one is described in detail. Rules are divided into several types. If a program rule is used, then it is possible to configure access of certain software to the Network. If for a port, then permission or denial occurs for it, a number of ports or a protocol.

You can also choose a predefined or custom rule. Further, the setup is more than clear. Specify the path to the program, select open or closed access. You also configure permission or blocking for a specific type of network. Give your profile a name and the setup is complete.

If you need more fine tuning, for example, prohibiting all software from connecting to a designated IP or port, or creating a list of “white” addresses, select custom rules.
