For the vast majority of households Windows users 7 and Windows 10 is quite suitable regular antivirus product from Microsoft. In the Windows 10 operating system, it is already built into a system called Windows Defender ( Windows Defender) and does not need to be downloaded and installed additionally. But for Windows 7 you will have to install by downloading the distribution Microsoft Security Essentials on the Microsoft website. In fact, this is the same product, but with different names for various systems.
Someone thinks Microsoft Security Essentials absolutely incompetent antivirus, but practice shows quite the opposite. This solution is quite capable of protecting your computer from malware, has a very powerful basic functionality, as well as absolutely does not slow down the operating system. That's why this decision can be used as permanent protection on computers running Windows 7 and Windows 10.
Why do they exist third-party antiviruses and what is the meaning of them? The answer is simple. There are different categories of users:
- Completely newbies who do not know and do not understand their actions need a "nanny" who will check each of their actions and allow / prohibit it depending on the danger of these actions. Accordingly, for this you need to control all elements of the system, which is what most antiviruses do. At the same time, they have one very serious drawback - they slow down the system very much.
- Average users who have already become accustomed to the computer and can quite distinguish the bad from the good, no longer need the constant control of the “nanny”, because they do not need excessive control and can interfere with their work. This often happens when such a user put a "nanny" on his computer.
- Advanced users want to control everything and not let the computer make any decisions on its own. This necessitates the installation powerful solution, which will allow you to comprehensively control the operation of the computer and allow it only those actions that the user wants to allow it.
In most cases, we are at step number 2 and there is no point in hanging a “gluttonous nanny” on the computer in this case. But Microsoft Security Essentials (for Windows 7) and Windows Defender (for Windows 10) are quite suitable and will cope with their tasks 100% without distracting us from work and without slowing down the computer. What, in fact, is what you need from an antivirus.
In the case of Windows XP, things are worse - you have to look antivirus solution on the side. Alternatively, you can.

Viruses appeared long before the operating room family Windows systems. Exactly 35 years ago, the first virus was written by a 15-year-old schoolboy for the Apple II PC. And after 5 years (in 1986) the “first sign” appeared on the personal IBM computer. As the Internet grew, so did the number of viruses. To give optimal protection OS Windows families From this "threat", Microsoft developed Windows Defender. What kind of program it is, what features it has and how to use it, read in this article.
About the program
Windows Defender - software by Microsoft, designed to prevent the appearance, quarantine or removal of spyware malware in operating Microsoft systems Windows. Defender has evolved from Windows XP to Windows 10, acquiring and improving its security features.
In the form in which the software product is presented now, it differs from similar free scanners systems. The Defender uses additional security modules that monitor suspicious software activity in certain OS segments in real time.
Opportunities
The defender allows the user to make changes in its functionality:
- Real time protection. Helps detect malware and prevent it from being installed or running on your computer. The protection consists of:
- Tracking the list of programs that automatically start at OS startup.
- tracking Windows installations related to system security.
- Tracking components and security related to Internet Explorer.
- Tracking interacting with the OS and with running programs services and drivers.
- Monitor Windows feature updates.
- Monitoring startup programs and all the actions they perform.
- Observations of tools and files that are used to register and autorun the software.
- Cloud protection. Allows you to send real-time data about potential security threats to Microsoft. Before sending, asks for user permission.
- Automatic sending of samples. Sending data is sent automatically, without notifying the user.
- Exceptions. The user can independently specify the file that he wants to exclude from scanning and processing by the antivirus.
Important! Defender will not check excluded files and this will make your system vulnerable to potentially dangerous software. Make exceptions at your own risk.
- Extended notifications. Defender sends automatic notifications so that the user automatically receives notifications about the health of the PC. If the function is disabled, the antivirus will only notify you of critical notifications.
- Autonomous Defender. The function helps to eliminate “especially serious” malicious programs from an infected computer. After enabling the function, the PC will restart and the troubleshooting will take about 15 minutes.
Good to know! On Windows 10 safe mode does not turn on by pressing F8 before Windows boot. The developers cut this feature to speed up the process of loading the operating system. .
