It's no secret that at present there are many different spyware and viruses that are aimed at controlling a computer from a distance. With the help of such programs, attackers can find out your passwords, personal resources, and also steal important information. After that, they can introduce code into the computer that will finally destroy your operating system.

To prevent this from happening, for the security of your computer, it is recommended to install antiviruses, activate the Windows firewall, which reduces the risk of computer infection. On the network, of course, there is also for security, but it is not a fact that it can be real, that is, it will not harm your computer.

Windows Defender - what is it?

In short and clear, this "defender" ensures the safety of the computer from the above fraudulent programs. Unfortunately, there are programs that the antivirus cannot detect. Therefore, this "defender" penetrates the program code of the malicious program. When Windows Defender finds such a program, it removes it.

From the moment you install and start Windows, Windows Defender will run in the background.

How to open Windows Defender?

To open Windows Defender, follow these steps:

"Start" → in the search bar enter the word " defender ».

What features does the program have?

If you have already entered the program, then in the top tab you can see a certain program control menu, which will be used to search for malicious programs, as well as other settings for managing the search and the program as a whole. You can set the time and date of scheduled computer scans.

If you select the menu " Check Options”, then the program will offer you three options:

1. Quick check . This is the easiest and fastest option. It is installed on the computer as standard, by default. If it is enabled, system files will be checked for the presence of virus files in them.
2. Full check . In this case, all files on the hard drive are scanned, as well as RAM. The scan time will depend on how busy your HDD files.
3. Custom scan . This item speaks for itself. The program scans areas that you choose.


As you can see, Windows Defender is based on antivirus programs. It also has various repositories that store remote programs and files.

For more adequate work of the program, it is necessary to update it periodically.

Also, in this program there is a so-called " Magazine". It lists all actions performed by the program and actions applied to other, dangerous programs.


If you click on the link " Allowed objects”, a list will appear that will indicate programs that have been allowed by the user and are not considered malicious, and the link “ Quarantine» has a list of potentially malicious programs.

How to enable and disable Windows Defender 7?


We have already figured out how to enter the program.

What to do if Windows Defender won't start? To do this, go to the "Start" menu and in the search bar enter the word " Services ».


We find " Windows Defender". We click on it. In the menu that appears, click " Run».

How to disable Windows Defender?

If your computer has Microsoft Security Essentials, Windows Defender will turn itself off.


Plus, if you click on the link " click here...", you get the following:


If you want to start this service manually, then you will not succeed either.


As you understand, Microsoft Security Essentials itself completely disables Windows Defender. By the way, it is possible that some antiviruses can do the same.

How do I update Windows Defender?

There are two ways to update the program:

1. Through the "Windows Update Center". In this case, the program will be updated automatically. But, for some users, automatic updates may be disabled, so the second option is needed.
2. The second option is quite simple, it starts from the moment you open the program. When you open it, you will see an inscription where you will be prompted to update the program for further work.


So, there is a button Check for updates". You need to press it. After you click it, the program will start connecting to Windows Update. The time it takes to search for and download updates directly depends on the speed of the Internet.


When the program finds updates, they will be installed.


After all the steps to update the program will be ready to work.

Hello, friends! While writing about Microsoft Security Essentials, I came across Windows Defender 7. I realized that I didn’t know anything about it and decided to write an article to clarify for myself why Windows Defender 7 is needed and when it is advisable to use it.

The main window of Windows Defender 7 is shown in the figure below.

If Windows Defender does not start, then you may need to manually start the service of the same name. Also, by searching in the Start menu, launch the "Services" utility

Finding a Service Windows Defender and double click on it. In chapter Launch type select from the dropdown menu Automatic (delayed start) and press the button " Run»

After that, we should start Windows Defender without any problems. If the service, for some reason, could not be started, then I would check the computer for viruses with two different utilities (for example, Dr.Web Cureit and Kaspersky). Then I would check for Trojans using MBAM. Rebooted and would try to start the service. If the result is negative, then I restored the system files. If now the result is negative, then I would think about reinstalling the operating system.

Let's hope that turning on and running Windows Defender will be easier.

How to turn off Windows Defender

Everything seems to be clear with the excluded files, folders and file types. If the defender, by mistake, reacts to a file that is known to be safe, then you can add it to the exceptions.

On the tab in detail, just like in Microsoft Security Essentials, I check the checkbox for checking USB devices so that the defender checks connected flash drives, external hard drives and other storage devices.

In chapter Administrator you can turn off the defender completely and allow the log to be shown to all users. If there are multiple users on the computer, you can let them see what Windows Defender 7 has found.

All with settings.

How to enable defender in Windows 7 through the registry

Valentina shared this method in the comments to this article. Thanks Valentina.

  1. We pass in the registry branch: HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows Defender to the DisableAntiSpyware key, and change the value (1) to (0).
  2. We restart the computer and rejoice, Windows Defender is working.

Conclusion

In this article, we figured out what Windows Defender 7 is. This is not a full-fledged antivirus solution, but only protection against spyware and other potentially dangerous software. That is Trojan protection. I will use it on very old computers (for example, on my grandfather's laptop), since the defender requires less resources than a full-fledged antivirus. My grandfather only communicates on Skype and looks at photos. That is, the likelihood of infection is minimal. I would be glad if you share your opinion on the use of Windows Defender. By the way, in Windows 8, the developers abandoned Microsoft Security Essentials and transferred all its functionality to Windows Defender 8, which also comes with the operating system. I wonder what will happen in Windows 10?

Error code 0x80070652 can appear when updating almost any Windows component. This happens especially often when Windows Defender tries to download its updates. Starting with the seventh version of the popular OS, most users have encountered such a problem at least once.

How to fix Windows Defender update issue.

When downloading or installing system security updates, especially if they have been delayed until later, a message with this code is most likely to appear. It is usually accompanied by the text "There was a problem with Windows Update." If you do not use regular updates, the problem will not make itself felt. There are 3 main ways to solve this problem.

System Restore

Windows Defender, like any other program, has its own update system. This means that many of its components are replaced by others as soon as they are no longer relevant. If you constantly create Restore Points, this will help in the fight against almost all program problems.

Is the code left and still pestering you? Then you can use another suggested method.

Computer update

Every time you install and uninstall programs, the integrity of the registry is violated. This cannot be avoided - Windows software always leaves its traces in the system. And even long after the removal, program elements are present in the registry.

You can deal with this using cleaners like CCleaner, or more versatile solutions - Windows 7 Manager will do a lot of system maintenance tasks just fine. However, the second program is paid, although not very expensive.

There is a regular way to update the system configuration so that important files are not affected.



You need to understand that error code 0x80070652 is a warning to the user that not everything is in order with the PC file system. It does not mean damage to files important to Windows, but it indicates that one or more programs are causing a conflict.

"Clean" system boot

Often, a conflict between system applications and third-party programs leads to the appearance of error code 0x80070652 in Windows Defender. Clean boot allows you to eliminate this factor by running only those applications that are required for Windows to work. Windows Defender should stop issuing alerts if the problem is in the wrong, "left" software.

How to set up and use Windows Defender 10

Windows 10 has a built-in tool to protect against malicious and potentially dangerous software - Windows Defender (Windows Defender). Despite this, many users do not use it on their computers, preferring third-party antivirus programs. Users are not aware of the existence of such a Windows 10 tool or do not trust it.

Microsoft recognized and validated the growing threat of spyware and malware by introducing Windows Defender to its operating systems a few years ago. Windows Defender was already available in Windows XP and Windows 7, but starting with Windows 8, Microsoft introduced an improved version of Defender that effectively protects your computer from viruses.

Due to the fact that the presence of two antivirus programs on the computer at the same time can conflict with each other, if you install a third-party antivirus program, Windows Defender is automatically disabled.

How to check if Windows Defender is enabled

To check if Windows Defender is active on your computer, just look at the notification area (to the left of the clock). Just click on the arrow to show the hidden icons and see if the fortress icon is there.

If there is no such icon, it means that the defender is not active or another anti-virus program is present on the computer. If you are not sure if you have an antivirus program on your computer, you can check if Windows Defender is enabled manually.

How to turn Windows Defender on or off

4 reasons to use Windows Defender in Windows 10

After the launch of Windows 10, users could often hear that this version of the operating system is the most secure. One of the reasons for this is also the much improved Windows 10 Defender. It is now more competitive with other antivirus software, and there are reasons why you can use it without worrying about having to install other programs:

  • Windows Defender is natively integrated into the operating system. It can be used immediately after installing the system and there is no need to worry about installing updates - the program is updated by Windows Update.
  • There is no charge to use Windows Defender. It is completely free.
  • A full-fledged antivirus with additional options such as: real-time computer protection, cloud protection, Windows Defender Offline, periodic scanning.
  • Very easy to use, does not require any additional settings other than the activation of standard functions, does not require additional PC resources for its operation.

Many users do not pay enough attention to protecting their computer from viruses and malware, using trial versions of paid programs as the main antivirus or antiviruses with outdated databases, as a result of which they suffer from operating system failures and errors, as well as data loss.

Perhaps for large enterprises that work with large amounts of important data, the features and capabilities of Windows Defender 10 will not be enough. But for the majority of home users who try to use free antivirus programs and tools whose functionality is limited, then Windows Defender 10 will be a clear favorite.

Windows Defender and Firewall in Windows 10 makes sure that the system is as safe and secure as possible.

When you start Windows 10 for the first time, Windows Defender monitors your computer's security by checking it for malware or unwanted software.

Windows Defender uses real-time protection to check every file you download or run on your computer.

To scan specific files or folders, select them, right-click (or press and hold), then select Scan with Windows Defender. If Windows Defender finds malicious items, the Windows Defender app will notify you and advise you on how to protect your computer.

  1. Click the Start button, and then select Windows System > Control Panel.
  2. Select System and Security > Windows Firewall > Turn Windows Firewall on or off > select the networks you want to change settings for > click OK.

Note. If your computer is connected to a network, network policy may prevent you from changing Windows Firewall settings. For more information, contact your administrator.

To temporarily disable real-time protection, follow the steps below.

  1. Click the Start button, and then select Settings > Update & Security > Windows Defender.
  2. Turn off real-time protection.

Stable operation of a number of services is required, which can freeze from time to time, which negatively affects the performance of anti-virus protection. During a reboot, all Windows Defender components and services are restarted. If the reboot did not solve your problem, then pay attention to the following solutions.

If a third-party antivirus is installed on your computer, then it is this one that can cause a conflict that causes performance errors. Incompatibility issues lead to slow system performance, application crashes, frequent freezes, and other problems.

When installing third-party antiviruses, Windows Defender is usually disabled. If you want to use only the built-in system protection, then uninstall the third-party antivirus and restart your computer. After the system starts, Windows Defender should turn back on.

Instructions (How to uninstall antivirus) and utilities (AV Uninstall Tools Pack) for complete removal of antiviruses from Windows are available on our website.

3. Threat cleaning

Right-click on the clock on the taskbar and select "Set date and time". On the settings page, enable "Set time automatically" and select your time zone.

7. Download the latest updates

Often, Windows Defender errors can be caused by an incorrect system update. However, Microsoft may have fixed the problem in a patch or new cumulative update. Make sure you have automatic Windows Update enabled and check regularly for new available updates.

To check, go to Options >

8. Check the zone setting and update the proxy in Internet Explorer

To do this, you need to manually do the following steps

  1. Command line

Surely, many users of the Microsoft system have a question: do you need Windows 7 Defender? In order to answer, it is first worth considering what the built-in antivirus is responsible for and what functions it performs.

Windows Defender features

The main task of Windows Defender is to find and block programs that are harmful to the system and user files, spyware, viruses, and rootkits. The built-in anti-virus software provides real-time protection. Windows Defender 7 can also clean the system of suspicious programs in one click.

The built-in program prevents infection of the system in two ways. In real time, it will help block a malicious application even before it is launched. This method is very effective for neutralizing threats while surfing the Internet. The second method scans system and user files for threats. This check is performed automatically according to a specified schedule: when the computer is turned on and off, and also at certain times of the day. Naturally, it is also possible to manually start scanning the system or individual folders and files.

Effective duet

Usually, in parallel with the work of the built-in defender, the Windows firewall is used, which will help to ensure that access to the network is restricted for unverified applications or programs specially selected by the user. The firewall has three access protection profiles:

  • public - will provide the maximum level of traffic filtering and will be appropriate in places with free Wi-Fi connection (cafes, shopping centers, metro stations);
  • working - has a less stringent filtering of transmitted information, as it is designed to work in a more reliable network;
  • the home profile has the lowest level of data filtering, because in home network, as a rule, there are only a few computers that do not pose a network threat.

Using Firewall and Windows Defender together will provide the maximum level of protection for the system and user data.

System updates

Of course, for the built-in protection to work correctly, you must remember to install the recommended Windows updates, which will provide up-to-date anti-virus databases and patches. The best option in terms of protection would be to set up automatic system updates. But on weak computers, this can lead to very unpleasant delays during the background installation of updates, and you may also need to restart the OS quite often, which will not be convenient at all, for example, when you urgently need to check your mail.

In order to prevent Windows from interrupting your work at the most important place, it is recommended that you choose to install updates on a schedule, which will allow you to carry out the process at a convenient time for you. It is also possible to set up a manual system update, but the user will have to remember to check for it from time to time.

Summing up

It is safe to say that the built-in antivirus will protect your computer from most threats if you follow the recommendations for its use. It will be a worthy free solution to the problem of viruses and will ensure safe browsing on the Internet.

It should be noted that the Windows 7 defender, which has very decent reviews, cannot provide full protection without the above measures (firewall, updates). Many users are still inclined towards paid protection systems such as Nod 32, Kaspersky and others, but this is the solution is quite individual. Here, as they say, the taste and color ... If desired, the Windows 7 defender can be turned off or turned on at any time.
