Svchost update windows 7. Check svchost for viruses. Editing the contents of the Prefetch and Tasks service folders.

Svchost exe loads the processor by 100% in Windows 7 what to do?

From the article you will understand what needs to be done if Svchost.exe loads the processor by 100%. Is it a virus or not? Now let's figure it out, many have had situations when the PC starts to hang and after calling the task manager you will notice that the process called Svchost.exe loads your processor by almost 100%. Of course, no one will like it and anyone will want to turn it off or delete it.

The second step to check if your computer is performing below expectations is to know the details of your processor and find out what software is in use. Single core processor is not recommended for next generation software. Therefore, if you run one of the above programs on the underlying processor, you will easily notice the slow processing of the process. However, if you are using lightweight programs and your processor is very slow, you can proceed to the next verification step.

No solution found

The latter, and perhaps the only analysis that actually displays numbers in your processor's performance, is easily achieved through the "Task Manager".

In detail. If you click and all processes indicate 0 as the processing value, click again to reverse the column.

Many people will immediately think that this is a virus. Looking ahead, I will say that it may be a virus (numerous viruses are disguised as system files), or maybe not. There are several services in windows 7 that are named by this name. Now I will try to correct this situation and stop the process unnecessary for you. Let's start:

What to do if Svchost.exe is loading the processor

1. Launch the task manager by simultaneously pressing Ctrl + Alt + Del on the keyboard.

Special attention to system processes!

If any process reports values above 97%, you can be sure that the application in question is the root cause of your problems. This is just one of the system processes, but of course there are others. Identifying them is very important and also simple. You should not make any changes to these processes, much less close them.

Thanks to this detail, the system knows which cores which processes will work with. By default, the system configures all applications to use kernels the same way, but this never happens. Of course, single-core computers do not have the means to enforce this rule. Customization manual setting only needed when an application is causing the system to slow down. However, it is important to be attentive to one detail: limiting technological proximity software may lead to undesirable results.

2. Launching the dispatcher, go to the Processes tab and from the bottom click Display processes of all users.

3. Sort the processes by clicking on the Image name section. Then I will find Svchost.exe and click on it right click mice. In the menu that appears, select Go to services.

This means that if you create a game to run only in the kernel, you will have a rather frustrating experience. Thus, affinity configuration can be useful in cases where intensive processing is not required. This is the typical case of video converters, graphic editors and other software that does not require real-time results. Anyway, below you can check how to change this setting.

Don't set all affinities for one core. Also, you should try to create a configuration in which processes are executed by different kernels. This way, you can use both software without noticing major performance issues. As the name suggests, the priority is for the system to know which processes are most important. Priority setting is only required if any application is causing a slow or machine crash.

4. In the Services tab that opens, all services that Svchost uses will appear.

5. It is necessary to find the service that loads the processor to the maximum. To do this, you need to disable all of the above services in order. I right-click on the service and click on the Stop service link.

Changing the priority is generally not recommended as this modification may cause various problems when using programs. Here's how to change the priority.

Caution: never select "real time" priority. This setting can lead to system instability.

Then you have to look at other factors. Viruses usually affect the overall performance of your computer, so it is important to use security software to ensure that this is not the case. Another detail that can impair the usability of a computer is the temperature of the processor. If not, then open the cabinet, clean or even replace the cooler. Some computers are set to shut down when the temperature is too high, meaning your problem might be hardware.

Important! After each disabled service, check the result.

The task manager will not be able to completely disable this service. It will of course be stopped, but not turned off. After rebooting the PC, it will start working again and load the processor.

In any case, basically, these tips should solve your problems. Share your experience and information with everyone!

Issues fixed in this update

IMPORTANT: If you install language pack after installing this update, it must be reinstalled. Therefore, we recommend that you install all required language packs before installing this update. Run only executable files from trusted editors, as executable files can potentially change or damage your computer's settings. However, the authors of malware such as viruses, worms, and Trojans deliberately gave these processes the same filename to avoid detection.

Another good reason why the svchost process loads the system is active work automatic update... If it is enabled and working successfully, then it is likely that the problem really is in it. For a solution, you will need to disable automatic updates.
The next way that I can suggest you to fix such a problem is to clean the operating system registry.

We advise you to check how secure your system is. A number of machine-translated articles are provided to you in addition to articles translated into French by professional translators. This allows you to have access, in your own language, to all knowledge base articles originally written in English language... Automatically translated articles are not always perfect and may include vocabulary, syntax, or grammatical errors. However, aside from these disadvantages, these articles should be enough to help you and help you solve your problem.

And the last option in my opinion, if a virus disguised as system file Svchost, then you need to carefully check your computer with an antivirus program.

So the conclusions:

Practice shows that, in addition to unwanted applications, the problem often lies in simple updates of the operating system. All other cases can be considered "special", since in almost all of them, everything is "tied" to a specific application. For this reason, it is impossible to describe all cases.

Global version This hotfix installs the files that have the attributes that are listed in the following tables.

In Windows 7, the most important process in the OS is Svchost.exe... Very often, Windows 7 PC users encounter a problem when this process heavily loads the processor. The load of processor cores can reach from 50 to 100 percent. Svchost.exe is an host process responsible for starting group services from dynamic DDL libraries... That is, the system uses this host process to start a group of services without creating unnecessary processes. This approach reduces the load on the processor and RAM. If the system slows down and Svchost.exe loads the processor heavily, this means that the OS is not working properly. This behavior of the system can be caused by malware, as well as malfunctions in the operating system itself. To deal with this problem, in this article we will look at all the ways to solve the problem with a high CPU load caused by the Svchost.exe process.

Viruses with the same file name

For more information about software update terminology, click the following article number to view the article in the Microsoft Knowledge Base. Additional Information about the file. Executable files can in some cases harm your computer. However, authors of malware such as viruses, worms, and Trojans deliberately give their processes the same filename to avoid detection. The process controls the operation of several areas of the operating system. As a final step, you will have to accept a system restart by clicking the Restart Now button.

First steps to troubleshoot Svchost.exe process

If you have a situation where the Svchost.exe host process is heavily loading the processor, then you should not immediately think that it is a virus. In addition to a virus, the OS itself may be the culprit for this problem. Below we will consider list of problems, and methods of fixing them:

Restoring normal processor operation using antivirus

If the above methods did not help, then most likely your Windows 7 infected with a virus... Typically, virus infection occurs from the outside. That is, via the Internet or via external storage data. If you have good antivirus, then most likely the virus will not pass. But there are times when antiviruses do not see new versions of viruses and let them pass. If your computer is infected, the Svchost.exe host process will load the processor up to 100 percent, and in the username you will see not the system names "LOCAL" and "NETWORK SERVICE", but a completely different name.

Thus, the system will become practically unusable. Have you ever seen how many processes are running on your computer? Each of these processes consumes system resources. This virus allows hackers to gain access to your computer and obtain personal data from your system. Please add the location to your ad blockers. We are a non-profit project and advertising is required to pay costs.

In any case, we respect your choice: if you decide not to unblock, you can still use the site without any restrictions. Before you waste time with this procedure, make sure your computer is indeed affected by the same defect following this iterator.

To get rid of the virus in the system, you need run full scan computer in Windows 7 to search for malware. Below we will consider an example of running a full computer scan using antivirus. Comodo Internet Security. Also, before running any antivirus to check the OS, update it anti-virus database... Let's move on and launch the antivirus Comodo Internet Security.

Before you start, make sure. Also try disconnecting from the internet and removing any malware, then restarting. Reading various forums shows that often the problem is related to the drivers installed by the security suites.

Once all of these controls are successful and the problem persists, we can fix the problem with dedicated analysis tools. The application we will be using to diagnose the problem should be running. Latest version at the time of this article's publication.

In the main window of the antivirus, go to the bottom tab “ Scanning”And a menu will open from which you can select scan options.

Step 9: update drivers and fix the problem

To obtain it, download the appropriate package for your operating system. At this stage, we have all the information we need to solve the problem. Let's go to the reference site for the problem device and look for an updated driver. If the problem persists, there are only two solutions.

Scan your computer for viruses

This happens when our device is in standby mode, which is suspicious. The solution to this problem is not obvious. Here are some ways to fix the problem.

Find and disable a service that is consuming a large processor

In the Processes tab, make sure all user processes are displayed. Right click and select Go to Services.

In our case, you need to select the item " Full scan". This option will scan the entire hard drive, identify malware and neutralize her... Shown below is the Comodo Internet Security scan window.

In others antivirus programs the principle of running a full PC scan is as similar as possible to the one discussed. Therefore, if you have a problem with the Svchost.exe host process, then feel free to run a full PC scan. For this example, we chose Comodo Internet Security antivirus for a reason. This antivirus has a built-in module called KillSwitch... This module is a task manager, which has advanced functionality. For example, KillSwitch can stop the process tree and revert back the changes made after that.

We need to know if the selected services are important to the functioning of the system. Alternatively, you can gradually try to disable services and control how the CPU return has returned to normal. This way we will find the service that will cause problems. To disable a service, right-click it and select Stop.

When you find a service that is causing problems, you must disable it constantly. We find the faulty service and then right click it and select Properties. We set the startup type to disabled and commit the changes. The next part of the guide is on the next page.

Also a feature of KillSwitch is checking running processes for trust... That is, if the process is untrusted, KillSwitch will find it and indicate this in the third column “ Grade". This feature of the KillSwitch module will help you more quickly identify the issue related to Svchost.exe and CPU usage.

It is also worth mentioning when the virus infects the antivirus itself or reliably disguises itself from it, as a result of which it does not see it installed antivirus... In this situation, the user will come to the rescue boot disk... This disk is a Linux-based portable operating system that boots from it. After booting from this disk, the user will be able to run a PC scan directly from the loaded operating system.

Such a check should find and neutralize viruses that force Svchost.exe to load processor cores. Most known viruses which load the processor using Svchost.exe are:

« Virus.Win32.Hidrag.d"- is a virus written in C ++. Once in the system, he replaces Svchost.exe... After that, it searches for files with the "* exe" extension and infects them. The virus is harmless, it does not harm the system and does not steal information. But constant infection of files with the "* exe" extension puts a heavy load on the processor.
« Net-Worm.Win32.Welchia.a"- this virus is an internet worm that overloads the processor through internet attacks.
« Trojan-Clicker.Win32.Delf.cn» - a primitive Trojan that registers a new Svchost.exe process on the system to open a specific page in the browser, thereby loading the system.
« Trojan.Carberp» - a dangerous Trojan that also disguises itself as Svchost.exe... The main purpose of this virus is search and theft of information from large retail chains.

High CPU usage due to Windows Update

On computers running Windows 7, a situation is often observed where the Svchost.exe process loads the processor and memory because of the update center... To check what exactly the update center is loading memory and processor, you need to go to " Task Manager"And with the help of Svchost.exe go to the services, which in this moment he rules. An example of such a transition is shown in the image below.

After such a transition, a window with services should open, where the service " wuauserv».

This particular service responsible for downloading and installing updates seven. The fix for this problem is quite simple.

In the Task Manager Services window, you can completely stop "wuauserv" or disable checking for updates in the control panel.

But disabling the "wuauserv" service is an ugly way out of this situation.

Disabling this service violates the security of the OS as a whole, since the installation of updates through the update center will be disabled.

You can solve this problem by manually installing updates. In order not to download dozens of updates from www.microsoft.com and then install them for a long time, it is best to use a set of updates UpdatePack7R2... The developer of this set is “ simplix», Who is also known by this nickname and is a moderator on the www.oszone.net forum. You can download this set at http://update7.simplix.info. Currently posted on the site latest version under the number 16.6.20. After downloading the kit, you can start installing updates. To do this, run the installer.

In the window that appears, click the Install button. After that, the process of installing updates will begin.

This process can take quite a long time and depends on the amount already installed updates... Update so offline Windows way 7 is possible constantly, since the author of the project is constantly releasing new sets. Also, after completing the installation of updates, you can restart the update center. This time, the memory and cpu issues should go away as these updates contain a fix.

Conclusion

In this article, we have covered quite extensively the problem associated with high CPU utilization due to the Svchost.exe process. Based on this, our readers will certainly be able to solve this problem and ensure the normal operation of the computer.
