How to disable one of the active protection components.

Screen Firewall Policies Allows advanced users to manage firewall rules to block unauthorized access while allowing authorized communications.

By default, the firewall settings are designed to provide best protection, if it is enabled. Therefore, we strongly recommend changing them only if you have a thorough understanding of the firewall. After making changes, click OK to save your firewall settings.

Note. Firewall is only available in programs Avast Ultimate, Avast Premier And Avast Internet Security .

Specifying Default Rules

Specify how the firewall should behave when encountering programs that are being launched for the first time and therefore Not having predefined application rules.

• Detect automatically(default): Allow Avast to choose the most appropriate setting for each program based on its behavior.
• Allow: Allow all programs that do not have predefined application rules to access the network.
• Block: Prevent all programs that do not have predefined application rules from accessing the network.
• Ask: Set to prompt you to allow or deny network access whenever the firewall encounters a program that does not have predefined application rules. If you choose this option, prompts may appear quite often, which can be annoying.

To apply different settings for network profiles Private And Public, check the box Use separate settings for each firewall mode.

Setting up a policy

Creating Package Rules

Other firewall settings

Use the tabs located on the left side of the window to manage different characteristics firewall behavior.

Network profiles

Screen Network profiles displays a list of networks that you are connected to or have connected to in the past from your PC. These networks are listed in order of how recently your PC connected to them. You can manage the firewall settings to change the profile and the settings specified for each network.

Specify what the firewall should do each time the network changes if the profile is different.

• Allow automatic profile switching: Allow Avast to automatically change its firewall profile when you connect to a known network with a different profile than the previous network connection. By default, this option is active.
• Show notifications about automatic profile switching: Warns you every time your firewall profile changes (if you change from a profile to Private on Public and vice versa). Selecting this checkbox may result in intrusive warnings.

Click the network information bar to manage the following settings.

• Name: Change the network name.
• Profile: Change network settings according to network type: Private or Public. We recommend using the profile " Public network» to all networks, except his private network, for example, when connecting to the Internet in a cafe, airport, etc.

The MAC address, if applicable, will also remain visible, but changes cannot be made to this field. The MAC address is the address of the router hardware.

Friends

Use the settings screen Friends to specify all trusted networks outside of your current network that are considered trusted by the firewall. These networks (called " Friends") are not affected by default firewall restrictions that apply to unknown networks.

Exceptions applied to the Friends list are only used when connected to a network with a profile Private. If the firewall profile is selected Public, default restrictions apply to all networks, including those listed Friends.

Note. Trusted networks are automatically included in the Friends list. It is not possible to change their configuration manually.

Additionally

Additional settings firewall are available to users who, for some purposes, need to make changes to their firewall settings.

• Maximum number of entries: Change the number of activity log lines in the firewall log. Reducing this number saves disk space, but reduces the amount of information in the partition Firewall logs.
• Log all blocked packets: When this setting is enabled, the firewall will log every packet it blocks. If you Not check the box next to this option, the firewall will only log connections. Typically, logging all packages is only required when troubleshooting security holes.

Determine what the firewall should do when attempting to scan a port.

• Enable automatic port scan detection: Allows the firewall to detect port scan attempts. By default, this option is active.
  Port scanning is a technique often used by attackers to identify vulnerable or unprotected devices on a network. If the firewall detects a port scan, the insecure IP address will be blacklisted and all communication to that address will be blocked until your PC is rebooted.
• IP address blocking time: Specifies a time period for the firewall to look for suspicious network packets in the recent network traffic log. The default period is 1,800,000 milliseconds (30 minutes). Increasing this value may cause false threat detections.

Specify the preferred value for direct access sockets.

• Enable Raw Sockets: Enable communication with applications that use direct access sockets instead of special communication protocols. By default, this option is active. Clearing this checkbox will improve PC security slightly, but will cause significant connectivity issues for all applications that use direct access sockets.

Screen Firewall Policies Allows advanced users to manage firewall rules to block unauthorized access while allowing authorized communication.

You will disable the firewall in the control panel, and on Avast - right-click on the icon in the lower right corner.... A window will appear there, click where Avast is with the left.... Settings will appear. They have updates... Set it to “update manually”... It sucks, of course, but it’s tolerable))

Hello! Here is a selection of topics with answers to your question: Help!!! How to disable Avast antivirus and what is a firewall?

How do I reset my password?

Avast antivirus has everything modern technologies, this is also heuristic analysis, removal spyware, sandbox and others, including the function of a personal safe account SafeZone.

The free version of Avast (which is used by more than 220 million people) is in many ways not inferior paid analogues, providing the necessary level of protection. Features such as heuristic analysis (allows you to identify hidden resources), the function of checking the system before Windows startup bypassing drivers (this unique feature is currently implemented only in Avasta), checking local network, all this allows us to conclude that Avast is the best free solution for home computer.

The paid and free versions have several differences.

Avast has also been ported to mobile devices on Android platforms, Palm, Windows CE.

Installing Avast 2015

To download the antivirus Avast 2015 go to the official download page, then click Go to download.

Today we will look at the free 30-day version of the type Premier, after reading which you can easily navigate in any version of Avast 2015 antivirus.

After this, we will be prompted to download the online installer - download it and run it.

Launch the Avast 2015 installer.

By the way, this is not a free version, I decided to consider the paid version PREMIER (although there are not so many differences) in order to familiarize you as much as possible. The free version lacks some features (but for the average user they are not critical). For your home, you can safely use exactly free version.

We agree that we wish to establish a 30-day trial version and press Typical installation.

If desired, you can also install along with the antivirus Google Chrome , but I recommend installing everything separately.

In the next window we also click Continue.

After this, the antivirus installation process will begin - first it is downloaded from the Internet, after which it will be installed.

Installation may take some time, depending on your internet speed.

After installation, an automatic system scan will begin, which you can disable immediately - to first set up the antivirus.

Another advantage is that there is no need to reboot after installation, as is typical for other antiviruses or firewalls (for example Agnitum Outpost).

After installation, two shortcuts will appear on the desktop - these are Avast Premier And Avast SafeZone.

What does Avast SafeZone mean?

Avast SafeZone This new opportunity process virtualization, which will be available only after a reboot. After starting this mode, you can use a secure browser Google Chrome.

With such a browser, you can view pages as if outside of your Windows. According to the developers, the browser SafeZone will allow you not to worry about the theft/interception of personal data (such as a password or others) when performing banking transactions, working with payment systems in the browser, as well as from the action of a keylogger (this is a program that records all keystrokes in a file and transmits it to the attacker).

The browser does not contain any modules or plugins that could reduce the level of security.

In order to launch Avast SafeZone, double-click on the shortcut on the desktop (or right-click and select open), after which your “office” will appear in a sense. To launch the browser, click on the first icon at the bottom of the screen (very reminiscent of the taskbar interface in Windows 7).

In the same way we can launch a notepad.

It will be useful to add your program to run it through the secure Avast account. To do this, click Add a new app to your bookmarks.

A program selection dialog will open - select the program and click Open.

After this, you will need to confirm adding a new program, click Add.

After adding it, the panel will have the opportunity to launch this program (in this case it is a browser Mozilla Firefox ) in protected mode.

Interface

Now let's move on to appearance Avasta, or rather what elements and what they are intended for. Open the antivirus window - to do this, double-click on the icon in the lower right corner (that is, in the tray), a window for managing the main Avast capabilities. The interface itself is designed in a modern and traditionally colorful style.

There are five tabs in total, let's go through them.

Overview tab

When you open the antivirus, we will immediately be shown the main tab - Review, which displays the current antivirus status. Also present on it quick access to the four main antivirus capabilities.

This scanning is a new verification method that allows you to search malware such as viruses, spyware, Trojans, etc. It will also help you find updates for your programs.

The process may take some time, it depends on the quantity installed programs/files on your computer.

Browser Cleanup. Allows you to clean your browsers from suspicious add-ons in the form of plugins. Some plugins can get viruses onto your computer.

Safety home network . Checking your local network for vulnerabilities. Search for possible problems in the operation of network devices.

SAFEZONE. A secure account in which you can safely carry out important processes without fear of data theft by intruders.

Scanning

This menu will allow you to scan for viruses, search outdated programs on your computer, network threats, possible problems productivity. Smart Scan involves a comprehensive system check.

Identify potential performance issues ( GrimeFighter) can help you make your computer a little faster.

Tools

In this menu, tools are available such as sandbox, firewall, secure connection with internet ( SecureLine VPN).

SecureLine VPN

Avast SecureLine VPN implies a secure connection using a paid VPN server. The truth is present and test mode in three days (trial).

This will allow you to visit pages not directly, but through a special secure server- it will be impossible to intercept your personal data, since all data is securely encrypted SecureLine VPN.

Sandbox

A sandbox is a special environment in which you can run suspicious program and determine whether it is dangerous for the system or not. Moreover, even if the program is actually a virus, its entire action will be limited to the sandbox - access to your Windows will be completely isolated.

To check the program, click on Run the program in the sandbox....

For example, if you add the Mozilla browser, then the process will be visible in the sandbox, its ID and the window title, but at the same time Windows will be protected from any influence of Mozilla (of course, the browser cannot harm the system, this is just an example).

Accordingly, to finish the program, you can click on Abort or exit the “tested” program.

Avast Firewall

Firewall is an important basic network component which is responsible for controlling program access to the network. Using a firewall, you can block a particular program from connecting to the Internet, or vice versa, allow it.

The window lists programs that were allowed by the firewall to access the network.

To configure rules manually, click Tune next to any program in the list. A window will open Application Rules, where you can set certain conditions for accessing the Internet for each application using a special slider. When changing the access level, a hint will be shown, so I think you will figure it out.

How to create a rule for a program?

In the same window Application Rules you can create a rule for a specific program in advance, to do this, click Create a rule for the application.

In the window that appears, select the program and click open.

Now you can deny or allow her access to the Internet, use the orange slider to do this. By default, added programs are included in the group Other(that is, others).

Monitor network connections

To open the connection monitor, click at the bottom of the window Network connections.

Monitoring connections will allow you to find out which program and at what address connects to the Internet, and thus identify those whose access is “better” to be denied.

For more detailed information, check all three boxes in the window Network connections(above the list of connections).

How to enable manual firewall mode?

If you want the Avast firewall not to work in automatic mode and not allow access to the network without you, then you should specify manual mode. To do this, go to the firewall settings (click Settings).

In the settings window that opens, Firewall Policies— select for programs that are not in the list: Ask.

You can also check the box for notifications about new rules if you are interested.

Well, we sort of figured out the firewall a little, now let's move on.

Shop

Tab Shop may be of interest to you if you want to purchase a paid version Avast.

Also on this tab you can compare Avast editions - Pro Antivirus(ensures the safety of your files on your computer), Internet Security(provides reliable control of network connections), Premier(comprehensive system protection).

Statistics

Window Statistics It is rather informative in nature - in front of you are many different graphs, a workload scale, and even something like a speedometer. The benefits of all this are debatable, but at your leisure you can look at the status of Avast components and the general state of the security of your system.

Settings

Click Settings to open the antivirus settings window. There are quite a lot of settings, so we will look at the most basic ones.

In general, it is better not to change the settings unless necessary - everything is already configured optimally.

How to disable icon animation when scanning?

If you are unsatisfied with the fact that the icon is animated during the scanning process (for example, it simply distracts you), then you can simply disable it. To do this, on the tab General uncheck Icon animation when scanning.

You can also disable it altogether, but I do not recommend doing this.

How to turn off sounds?

When antivirus sounds disturb you or you are working, they can only distract you. To turn off sounds, on the tab General open submenu Sounds and uncheck Enable Avast sounds.

How to set Avast to password?

If you are not the only one using the computer, then it would be a good idea to set the antivirus to a password - so that other users cannot change its settings, thereby possibly significantly reducing the security of the computer.

To do this, on the tab General open submenu Password and set a password to access the settings.

You can also specify which settings will be accessible only with a password - to do this, check or uncheck the required items below.

How do I reset my password?

If you forgot your password, then it’s okay (but it’s better not to forget it). It can be deleted, to do this you need to delete the file aswResp.dat. from the settings folder. This method worked before, I hope it does now too.

Everything must be done only (!) in safe mode.

In Windows 2000, Windows XP, the Avast settings folder (any symbols can be used instead of asterisks):

C:\Documents and Settings\All Users\Application Data\AVAST Software\Avast
or:
C:\Documents and Settings\All Users\Application Data\Alwil Software\Avast*\

On Windows Vista/7/8:

C:\Users\All Users\AVAST Software\Avast\ or C:\Users\All Users\Alwil Software\Avast*\

and in this folder delete the file aswResp.dat.

How to disable pop-up messages?

If you are bothered by notifications about other Avast products that pop up and distract your attention, you can turn them off. In the settings (tab General) uncheck the boxes in the drop-down menu Pop-up messages.

How can I immediately add a program to exceptions?

Have you installed an antivirus and do you have programs that you are confident in? You can add them directly to the exclusion list so that Avast allows all actions for them and does not ask you.

Open submenu Exceptions(tab General) and press Review, then select the program folder (opposite the folder, check the box in the window Select areas, you can select more than one folder at once) and it will appear in the exclusion list.

To add a new program, click the button Add, after this the field will appear (enter file path), and then as was written above.

How to disable one of the active protection components?

If for some reason you do not need anti-spam protection, for example, then you can disable this component or another (in theory, this will reduce the consumption of computer resources). To do this, on the tab Active protection Change the slider next to the component you want to disable. I don't recommend turning it off Firewall or Screen file system .

Remember that by disabling one or more components, you reduce the level of security. The antivirus components do not require a lot of resources in terms of resources; it is better not to disable them unless you are absolutely sure about it.

Running the program only in SafeZone mode

You can configure the program to run only in protected virtual mode SafeZone- for this on the tab Tools click Settings.

In the window that opens, go to the tab Virtualized processes, where add a program that will only run in mode SafeZone.

You can also add an entire folder of installed programs - then all programs will also be launched only as virtual processes.

How to disable Avast antivirus?

To disable the antivirus, right-click on the Avast icon in the tray, then go to the menu Firewall management and select Disable permanently(or disable Avast antivirus for a while):

After this there will be a warning and if you are sure, click Yes.

Please note that in this case you are completely unprotected from viruses or malware, so disable your antivirus only in extreme cases.
