Already many times I have been asked various questions about, for example, “Where to download offline updates”, “How to send a suspicious file to the Microsoft laboratory for verification”, etc. Moreover, with similar questions, users from search engines come to my blog and do not find an answer. So I decided to write this article.
As an introduction, I want to immediately note that it is a high-quality and at the same time free antivirus from Microsoft for home users and small businesses (up to 10 PCs), the engine of which is based on a commercial Forefront Endpoint Protection. It possesses all modern anti-virus technologies such as signature check, heuristic analysis and cloud protection mechanisms.
During the installation of the client, special components are added that allow building protection at the kernel level, including detecting rootkits. Agree, only OS developers can have all the necessary tools that work at a very low level, the rest of the vendors have to somehow get out.
The main advantages of MSE are the following:
- Free
- Undemanding to resources
- Integration with
- Protection against Internet threats (integration with)
- Dynamic signature service
- Network monitoring system (protection against network exploits)
So, I will try to answer the most frequently asked questions from users:
Q: How often are Microsoft Security Essentials signature databases updated?
A: MSE anti-virus with default settings is updated once a day, at the same time at which it was installed. But, .
Q: Why does Microsoft Security Essentials disable Windows Defender?
A: Windows Defender is included with Windows Vista / 7 and is designed to remove, quarantine or prevent spyware. Microsoft Security Essentials it is a full-fledged antivirus, which incl. protects against spyware too. Therefore, if you installed it, then Windows Defender is no longer needed.
Q: MSE is displayed in yellow and reports that the PC is "Presumably unprotected". What does this mean, and what should be done in this case?
A: Anti-Virus displays a similar message in case the signature databases are out of date, or a system scan has not been performed for a long time. Try to update your antivirus databases and conduct a full system scan.
In case, if this does not help, then you are probably using utilities for cleaning the system, for example CCleaner.
Q: How can I update the antivirus on a computer that is not connected to the Internet?
A: You can download offline databases on the official website:
Q: When copying an executable file to a computer, the antivirus cannot identify it as malware, although it detects a threat when launched.
A: In the antivirus settings, set the option: Scan archive files. The point is that this executable file is actually a malware archive. By default, MSE does not scan archives.
Q: How can I send a file to the Microsoft Antivirus Lab for review?
A: You can send a file for verification to this address:
Q: How does the Dynamic Signature Service work?
A: If during the analysis the file is regarded as suspicious (for example, it tries to immediately change the protected parts of the OS), but the signature of this virus is not in the database, then a file profile is generated, which is sent for analysis to special Microsoft services - DSS (Dynamic Signature Service), SpyNet and MRS (Microsoft Reputation Services). If the signature already exists in the update database, but it has not been downloaded, the databases are automatically updated. The signatures contain not only a part of the "body" of the virus, but also some typical scenarios of behavior that make it possible to unambiguously determine the maliciousness of the program.
Q: How does the network monitoring system work
A: The network monitoring system provides protection against network exploits that use network vulnerabilities to infect a computer. It checks the traffic of the network to which the computer is connected and suppresses known attacks in advance. It requires the Windows Filtering Platform (WFP), which is available in Windows Vista and Windows 7. Network Monitoring does not work in Windows XP.
Q: Where can I go for technical assistance in case of problems?
A: You will be able to provide competent and qualified technical assistance with Microsoft Security Essentials and other Microsoft software products on the official resource Microsoft Community http://answers.microsoft.com/ru-ru/protect/forum/mse

Windows Defender is a suite of modules from Microsoft designed to track suspicious changes and eliminate potentially dangerous components. Various settings are available in the program and the ability to disable it as unnecessary. This method is identical on all Windows versions.
Understanding Windows Defender
The defender takes over the functions of the antivirus if it is not available. In practice, the application in question guarantees protection only against the so-called. "Trojans". To combat other malicious products, you need to install third-party antiviruses. The developer of the defender additionally notifies the owner of this.The product arsenal is quite rich. The Defender lets you do the following:
monitor autostart;
monitor security settings;
monitor applications that activate with IE;
control browser settings;
regulate the work of various files and add-ons that start with the browser;
monitor the functioning of drivers and services;
regulate the actions of installed and already installed programs;
keep track of files and add-ons for registering and launching various software products;
control the order of updating OS modules.
The list of functions may vary depending on the version of the defender and Windows itself.
Turning on the defender
To turn on the product and check if it works correctly, go to Start.
The screenshot shows the window of the product in question. In all current versions of the OS, the menu has almost the same appearance.
If the defender won't turn on, activate it yourself. Find through the search bar in the "Start" program "Services" and go to it.
Open the defender service. Go to the Launch type tab, select automatically (delayed launch) in the drop-down list and enable the defender by clicking on “Launch”.
The defender will be activated.
Disabling the defender
If necessary, the defender can be turned off directly from its settings.In Control Panel, turn on Small Icons and then look for Windows Defender.
Open the "Programs" item.
2. Open the branch: Local Group Policy Editor -> Local Computer Policy -> Computer Configuration -> Administrative Templates -> Windows Components -> Windows Defender or ( Endpoint Protection) -> Real-time protection and in the right window select Disable real-time protection
Good day!
I completely agree with you, Windows Defender completely replaces the paid antivirus, while not slowing down your computer. Finally, Microsoft has made something that works and is convenient.
Windows Defender may be turned off for you for 2 reasons:
1. You are using a work computer, and your system administrator turned off the defender, for example, to use a different antivirus.
2. You installed low-quality software that turned off the defender. Usually all sorts of dubious antiviruses and "security programs" do this. They are not made for your protection and themselves, to some extent, are viruses, therefore they disable the defender. But this is a topic for a separate article.
Whatever happens, turning on Windows Defender is not difficult, more on that below.
How to enable Windows Defender:
We will use the registry to enable Windows Defender. This is the easiest method and works on all Windows editions.
1. Press the Win and R keys at the same time (for details on the Win key in our article:), enter "regedit" in the window that appears and press Enter:
2. Navigate through the directory tree on the left: HKEY_LOCAL_MACHINE -> SOFTWARE -> Policies -> Microsoft -> Windows Defender:
Go through the subsections of the "Windows Defender" folder on the left, look on the right for any options that start with "Disable". When you find those - click on them and set the value "0".
3. Restart your computer and try to re-enable Windows Defender: Press the Win S buttons, write "Windows Defender" in the search bar and select an application from the list.
It will most likely start up and work fine. If not, follow the steps below.
4. Press the Win R keys, write "services.msc" in the line and press Enter. Find Windows Defender Service in the list and start the service if it is disabled:
If you have any questions or need clarification, please, or leave a comment.
In the latest versions, the "eight" and "ten", the Microsoft operating system has a built-in antivirus program that runs by default. OS Defender works autonomously and is designed to scan and remove or quarantine any malicious codes and modules. If you install third-party antivirus software on your computer, it will disable Windows Defender. At least this is what many antiviruses do. The latest version of Microsoft's Defender is much more efficient, and many users are content with this built-in antivirus software.
But there are times when Defender has to be disabled, for example, to install a computer application or entertainment content, if the defender considers it to be malicious. In our article, we will introduce you to a step-by-step guide on how to disable and re-enable the operating system defender of the last three versions.
Also, when Windows Defender stops working, if it does not give permission to install the application or after it deletes files, you will also need to disable the spy filter, which monitors all installed programs on computers. Perhaps the reason is not in the defender, but in the filter itself.
The latest version of Microsoft OS has received updates for Defender, and now it can be disabled through the task manager.
But if you uncheck the box from the automatic loading of the defender, it does not stop its work, but only hides the Windows Defender icon itself.
Disable Windows 10 and Windows 8.1 Defender
Disabling Windows Defender in the eighth and tenth versions of the OS is different. For the latest version, a more complex algorithm will be required. We will write everything down in detail, step by step, so that unprepared users can cope with this procedure.Use the Control Panel to start the shutdown procedure. The most elementary and fastest action is right-clicking "Start" and selecting a section.
Having entered the section, for a faster search, switch the view in the upper right corner to "Large Icons". Select Windows Defender.
If, when you start the main Windows Defender window, you are notified that the defender has been disabled, then you are using another antivirus software on this computer.
Now there are a few things to do. They will be different for each version of the operating system.
Windows 10
If you use the standard shutdown method, you may not achieve the desired result. But in some cases it works. Follow these steps:
The antivirus program will turn off, but for a while. After 20 minutes, it will resume its work again, but this time will be enough for you to install the application or game.
In the event that you want to disable Windows Defender for a long time, you must use other methods. Disabling permanently is possible using the Group Policy Editor or the registry program. For owners of Windows 10 (home version), only the second method is suitable.
Disabling the OS antivirus program through the Group Policy Editor is as follows:
Disabling the built-in antivirus program of the OS through the registry editor is as follows:
If you set the correct value for the "DisableAntiSpyware" parameter, the program will no longer start unless you do it yourself. The icon will also disappear when the operating system is restarted. You can also remove permanent pop-up messages about disabled Endpoint Protection by clearing the corresponding check box.
If you are unable to disable the offline antivirus software using the methods described above, use the dedicated antivirus software. They are free and allow you to quickly and efficiently disable your antivirus software from Microsoft.
Windows 8.1
In Windows 8, disabling Endpoint Protection is easier. These three steps will help you quickly disable your antivirus software:
The system will inform you that the anti-virus computer scan service is disabled and does not scan in real time.
Disable Windows 10 Defender using free software
If the actions to disable Endpoint Protection are ineffective for some reason, we recommend that you use professional tools - special programs. For example, it has proven itself well Updates Disabler is a tool that manages all automatic updates for the Microsoft operating system. The program has Russian-language support and is easy to use.
It was originally designed for those users who do not want to receive automatic system updates. But then its functionality was expanded, and now you can use other options, for example, disable Endpoint Protection.
There is also a product of German software developers, a program Destroy-Win-10-Spying... It allows the user to avoid submitting personal information that Microsoft collects. To enable the extended functionality of the program, you need to enter a special mode. In this case, Microsoft antivirus software is disabled automatically.
Windows Defender writes Application disabled (how to enable)
If you want to enable the previously disabled Endpoint Protection "permanently", we recommend that you follow a few step-by-step steps, which will be discussed below. Using these methods, you can enable the built-in anti-spyware service in Windows 8. To enable the service in Windows 10, you need a more detailed guide.If you click on Windows Defender from the Computer Control Panel and receive a notification that it is disabled and that the service does not scan your computer in real time, this may mean the following:
In the tenth version of the operating system, Endpoint Protection is enabled by a simple click on the notification. As soon as you click on the message, the service will be automatically started by the system. And if you disabled the Defender using the policy editor or the registry, you need to do all the steps described above, but in reverse order. For example, set the parameter "DisableAntiSpyware" to "0", etc.
To enable the Endpoint Protection service on the Windows 8 operating system, click on the notification area to open the Action Center. There will be a notification that the computer is at risk because the antivirus service is disabled. To start, click on the enable notification.
