The operation of the Windows operating system is a complex process, which is possible only with the proper functioning of all software components. MacOS is also quite difficult to work with, but users do not have the ability to monitor system processes. In Windows, you can view all executable files in the "Task Manager", and some inexperienced users can scare them. A vivid example of a file that triggers an alarm is svchost.exe. Quite often in Windows svchost.exe loads memory or processor, and there is a feeling that it is a virus. Is this true? Let's understand.
How to protect yourself from re-infection
This does not mean that all programs of this color will be malicious or that all viruses are such, but first it is worth checking them. Putting the mouse over the programs, you will know the full location of the file. In the case of services, you will find out which services are working in this process. These are programs that perform tasks in the background. They are necessary for the proper functioning of the system. To identify suspicious programs, it is also useful to include signatures. In this case, you will see a new column with information about the company responsible for the program, and if the information was checked successfully.
Svchost.exe: what is this process, what are its functions and why?
The common view is that svchost.exe is a virus that has under itself the basis, but in practice, most often, this process does not carry any threat in itself. If you understand the functional responsibilities assigned to the this file, it is necessary to connect dynamic DLLs to programs and services that can not work without them. Each program uses its own svchost file, which can be located in different folders of the Windows operating system. 
How to get infected from this malicious program?
Generally speaking, viruses do not have a valid signature. Again, this does not mean that all unsigned programs are malicious, but this only reduces the amount of software that you need to suspect. The column just quotes this to confirm the strength of the instrument. Internet connections, performance, memory.
When you right-click the process and select "Properties", you can access a series of information. Try changing the "Memory" option. You can search the contents of the program memory. Click the "Process Memory" tab. Check the "Virtual Size" and "Working Set Size" parameters. Because of how the memory manager works, there is no single value for "memory usage" of the program. These two values-the virtual size and the working set-respectively determine the total usage of program memory and the approximate value of the actual amount of memory that the program uses.
The most common file svchost.exe can be found at the following addresses:
- C: \\ WINDOWS \\ system32
- C: \\ WINDOWS \\ Prefetch
- C: \\ WINDOWS \\ winsxs \\ amd64_microsoft-window
- C: \\ WINDOWS \\ ServicePackFiles \\ i386
If the file svchost.exe is located in other folders - this is an excuse to sound the alarm, but not an indicator that it is a virus. This rule also works in the opposite direction, if svchost.exe is even located in one of the above folders, it may well be a viral software.
Pay more attention to the working set, but if the value in the "virtual size" is too large, be careful: the program can suffer from a memory leak, which means that eventually it will pull out the memory that it does not need. Identify the process responsible for the window. If you want to know which process list is responsible for the window, you can use the "sights" next to the binoculars. You need to click and hold the mouse button, and then place the pointer in the desired window.
This is due to the fact that the program, while working on the file, should inform the system that it will do it. Two programs can not open the same file at the same time to prevent corruption or loss of data. There the file is locked before restarting. By clicking on the binoculars, you can enter the name or part of the file name.
Determine in which folder the currently active svchost.exe processes are located very simply. To do this, follow these steps:
On Windows 8 and Windows 10 operating systems, you can see through the "Task Manager" a list of services that use the svchost.exe process. To do this simply - you must click on the suspicious process with the right button and select the "Go to services" item. It is worth noting that the names of many services are unlikely to be able to tell an ordinary computer user about something.
You can find out which one is open. You can double-click on the result that appeared. You immediately go to the process, and the file is "locked." But be careful: if you still need data from this file, it is better to close the program than forcefully close the file. If you have any questions about security, you can use it to use the comment area below.
All comments are read. He created and edited a Security Line, a security site and a forum that offers a free digital pest removal service, among other activities. This includes any other software that is open on the taskbar. 3 Disconnect the computer from the Internet. You can do this by right-clicking on the My Computer icon and selecting Properties. Then, on the System Restore tab, select the Disable system restore on all drives check box. This is important, you will also need spyware infections with a good full solution that will protect you from all Internet threats.
The svchost.exe process may not be a virus, and if it loads the system, you should consider 2 scenarios:
- The computer is infected with a virus that sends out spam, extracts crypto currency for its creators or transfers other data to intruders;
- Due to inattention, the user does not notice that the malicious process is only hidden under the guise of the svchost.exe system library, in fact it is not.
If the computer is infected with a virus, and because of this the svchost.exe process loads Windows 10 or an earlier version of the operating system, you should check your computer for popular antivirus software. Be sure to install Firewall, which will provide network security for your computer.

In this case, you will have to restart the service that it is working with. If you put the cursor over processes, you'll see which services are running. The information in this Knowledge Base article is addressed to a working environment where the system administrator is able to follow the instructions described below. If your antivirus program can effectively eliminate the virus and update all affected systems, reading this article will be redundant.
In the second case, you should recognize the malicious file svchost.exe, which is not, and then delete it.
How to distinguish svchost.exe from a system file
If the svchost.exe process loads memory or the CPU, you should verify the validity of the file it refers to. To do this, carefully check the name of the executable process. Below, we give a few tricks of intruders, which substitute the process svchost.exe for another, but close by name. Most often, the following schemes are used to disguise the virus:
If your computer has been infected with this worm, it may not be symptomatic or that one or more of the following symptoms occur. Among them are the following. Use secure passwords Administration, which are unique for each computer. Do not log on to computers using domain administrator credentials or other credentials that allow access to all computers. Make sure you have installed latest updates security for all systems. Deleting any overflow permissions for shared network resources, including the rights to write to the root of each resource. The self-cleaning tool can also remove this infection.
The above list only the most common options to disguise the virus, but there may be others. Take a close look at the process called svchost.exe and all the letters were spelled out in Latin.
In case you find a process that is masked by svchost.exe, but it is not, it should be deleted. It's quite easy to do this if you use the AVZ program.
A malicious program represents a user who logged on to the system and accessed network resources using the credentials of the user who launched the login. The server service must be temporarily disabled when the malware is removed from the environment. This is especially true for production servers, since this affects the availability of network resources. Once the environment is cleaned, the server service can be reactivated. If you incorrectly modify the registry, this can cause serious problems, and then carefully follow these steps: create more protection backup copy Registry before its modification, so you can restore it if there is a problem.
- This behavior can spread malware.
- Create a server service.
- This section, method, or task describes how to modify the registry.
How to remove svchost.exe from the AVZ program
Known antivirus utility AVZ is able to detect and remove unwanted programs, including viruses. It is distributed free of charge and has many useful functions. The AVZ program's plus is that it does not need to be installed on system disk. AVZ can be launched from a flash drive, external hard drive or directly from the downloaded archive.
Checking system cleaning
To check, compare the list in the service table with a similar system in which the infection is present. Pay attention to the name of the malware. This information will be required in the following order. Notes to the table of services. Replace the permissions for all child objects with the appropriate permissions specified here.
- Add these permissions to those listed here.
- Quit Registry Editor, and then restart the computer.
- One of the launch paths was not deleted.
To delete the svchost.exe file using the AVZ utility, you must do the following:
begin SearchRootkit (true, true); SetAVZGuardStatus (True); QuarantineFile ("path to the virus", ""); DeleteFile ("path to the virus"); BC_ImportAll; ExecuteSysClean; ExecuteWizard ("TSW", 2,3, true); BC_Activate; RebootWindows (true); end. Instead of the words "Path to the virus" highlighted in red, it is necessary to register the location of the svchost virus process. Above we have already told how to determine where the virus file is located, which is masked by svchost.exe. Copy the path to it (or write it manually) and paste in place of the highlighted red words. Attention: You can not remove quotes from the script - only letters marked in red.
After complete purification of the environment
Scroll to the end. . The following table lists the default permissions for each operating system. These permissions apply before the changes proposed in this article are applied. These permissions may differ from the permissions in your environment, so it is recommended that you take your permissions into account before making any changes. This is necessary to restore the settings at the end of the virus removal process.
Issues that are fixed in this update
Attention! However, translation is not always ideal. It contains errors in the binding of words, sentence composition or grammar, just as foreigners make mistakes when speaking in Czech. Microsoft is not liable for inaccuracies, errors or damages resulting from translation errors, or using incorrectly translated instructions in the client article.
Method 1
Method 2. Beware, this operating system is poisonous.
After successfully deleting the file that posed as svchost.exe, we strongly recommend that you scan the computer for viruses. There is a high probability that one of the programs generates new files that automatically start in processes and pretend to be svchost.exe.
Dangers lie everywhere. A bad driver may cause the entire system to malfunction. Incomplete applications leave a mess of the registry, which is the source of new problems. There is no panic. The chip will show you step by step how to perform a detoxification treatment that will return your physical form to your system. In addition, we will take precautions to ensure that systematic toxicity in the future is not so simple. How did you know that your system was poisoned? The processor is still heavily loaded, the windows open too slowly, the system startup is tedious, you need to wait a long time.
