To protect the Windows 7 operating system, you can use an antivirus from Microsoft, called Microsoft Security Essentials.

The name of the antivirus “Microsoft Security Essentials Windows 7”, consisting of 4 English words, is not easy to remember, so below we will also call it “Microsoft Antivirus for Windows 7”.

You can install it from the Internet for free from the official Microsoft website if Windows 7 on your computer is licensed. This antivirus is available for both 32-bit and 64-bit Windows 7 operating systems.

Information from the official Microsoft website about the antivirus:

Microsoft Security Essentials comes free*. It's simple to install and easy to use. It works quietly and efficiently in the background without distracting you or forcing you to update.

* Internet access charges may apply during download.

The appearance of the Microsoft Security Essentials program window is almost identical appearance windows of the Windows Defender program, created for the Windows 8 operating system. Windows Defender 8 was described in the article. And these antiviruses work in a similar way.

Unlike Windows 8, where the Windows Defender Service is a full-fledged antivirus, in the Windows 7 operating system the similar Windows 7 Defender is not a full replacement for antivirus software in real time (at the time of access).

For Windows 7, a full-fledged antivirus is the additionally installed Microsoft Security Essentials program, which can be downloaded for free from the official website using the link above. Moreover, after installing Microsoft Anti-Virus for Windows 7, Windows Defender is automatically disabled, transferring its functions to the installed anti-virus program.

If you decide to use Microsoft Antivirus for Windows 7, then other antivirus programs, if they were installed on your PC, should be disabled or completely removed from the computer. Otherwise, antiviruses will conflict with each other, perceiving each other, perhaps even as an infected virus program.

Setting up Microsoft Antivirus for Windows 7

Performed on the “Parameters” tab (number 1 in Fig. 1). On this tab you can configure the following options:

1. Option " Scheduled check"(number 2 in Fig. 1) allows you to configure the settings for automatically scanning your computer using Microsoft Anti-Virus for Windows 7.

  • Automatic scanning of your computer using this anti-virus program can be configured for a given day of the week, for a given time, and for the type of scan (quick, full or special).
  • It also requires that you automatically search for and install updates for virus and spyware definitions.
  • The maximum load on the PC's central processor for the duration of the scan is also set.

Setting up a scheduled scan (number 3 in Fig. 1) allows you to automatically run a scan of your computer for the presence (absence) of viruses and spyware, regardless of whether the PC user himself remembers this or not. Of course, for the automatic check to work, the computer must be turned on and booted at the specified time. This is the only thing required condition in order for the program to scan the PC without user intervention.

The checkbox opposite the inscription “Check for the latest versions of virus and spyware definitions before the scheduled scan” (number 4 in Fig. 1) allows you to perform automatic updates antivirus program to obtain the latest virus and spyware definitions from Windows Update. The latest versions of definitions are a guarantee that the antivirus will not miss and neutralize the latest versions of viruses and spyware.

If you have a fast PC, then to speed up the computer scan, you can use up to 80% of the PC processor power while checking the computer for the presence (absence) of viruses and spyware, as shown by number 6 in Fig. 1. For slower (older) computers, it is better to set no more than 30-50% if you intend to work on it when checking the computer.

The option of using 80% processor power on weak PCs is suitable if, during a scheduled scan, you refuse to do any other work on the computer until it is completed. Also for this purpose (launching Microsoft Anti-Virus for Windows 7 only on a PC on which no work is being done), you can check the box next to “Run a scheduled scan only when the computer is turned on but not in use” (number 5 in Fig. 1).

2. Option " Default Actions"(yellow number 1 in Fig. 2) allows you to configure Microsoft Antivirus for Windows 7 to take action if threats of various levels are detected.

Rice. 2. Configuring default actions of Microsoft Anti-Virus for Windows 7

For threats of the “Critical” level (that is, very dangerous, number 2 in Fig. 2), options are provided

  • "Recommended Action"
  • "Delete" and
  • "Quarantine".

“Delete” means permanently removing a detected infected file from your computer.

“Quarantine” means automatically placing an identified dangerous (infected) file in a special place on the computer in the so-called “quarantine”, where in the future this file will be available only to the Microsoft Antivirus for Windows 7 program.

For threats of the “High” level (number 3 in Fig. 2), there are also 3 options described above.

And for threats of the “Medium” and “Low” levels (numbers 4 and 5 in Fig. 2), in addition to the 3 options described above, there is also a 4th option “Allow”, which means permission to save the detected presumably infected file unchanged. But it is better not to do this, and, again, for all threat levels it is preferable to set the first default action option: “Recommended action”.

3. Option " Real-time protection"(number 6 in Fig. 2) allows you to turn PC protection on or off in real time, that is, directly during operation. Enabling real-time protection is a mode of constant monitoring of everything that happens on the computer in order to prevent viruses or spyware from entering the computer. It is recommended to set this option to “Enable real-time protection (recommended).” In this mode, if any attempts are made to penetrate a PC by malicious programs, the user will be immediately notified, and the suspicious file will be deleted or isolated.

4. Option " Excluded files or locations"(number 7 in Fig. 2) allows you to set exceptions for certain files or folders that should not be scanned by Microsoft Anti-Virus for Windows 7.

Option " Excluded File Types"(number 8 in Fig. 2) allows you to exclude files with certain predefined ones from being scanned for viruses and spyware, for example.xls, .xlsx, .jpeg, etc. This same Microsoft Anti-Virus for Windows 7 is allowed not to scan files with the extensions listed in the restrictions. It is also not recommended to do these restrictions on your PC, as this can also lead to your computer becoming infected with viruses or spyware.

6. Option " Excluded Processes"(number 9 in Fig. 2) allows you to exclude processes of the Windows 7 operating system so that they are also not subject to control and scanning by Microsoft Anti-Virus for Windows 7. And here it is not recommended to set any exceptions; the exceptions page should be empty so as not to “catch” a virus or spyware.

7. In the option " Details"(number 10 in Fig. 2), it is advisable to check the boxes only next to the inscriptions:

  • “Scan archived files”, which will allow Microsoft Anti-Virus for Windows 7 to unpack archives, select files in them and scan them for possible infection with viruses or spyware.
  • “Scan removable media”, which for Microsoft Anti-Virus for Windows 7 means the need to scan files and folders not only on the built-in internal drives of the PC, but also on external drives, flash drives and other storage media connected to the PC. This improves your computer's protection by preventing viruses and spyware from entering your computer through external hard drives, flash drives, memory cards, etc.
  • “Delete quarantined files after 3 months”, which allows you not to store infected files on your computer for longer than 3 months. If during this time no decisions are made regarding these infected files identified by Microsoft Antivirus for Windows 7, the files will be automatically destroyed without further possibility of their recovery.
  • “Automatically send sample files if further analysis is required” so that the company can take appropriate action to improve the protection of Windows computers.

8, In opia " MAPS"(number 11 in Fig. 2) sets the level of participation of the user's computer in the MAPS service. This service is designed to send information to Microsoft about detected unwanted programs. This allows Microsoft to respond more quickly to possible new viruses and spyware and speeds up the development of anti-virus programs and applications. It is recommended to set a “Basic Participation Level”.
