هو جزء لا يتجزاء من ويندوز إكس بي وويندوز 2000 لأنه ضروري لبعض البرامج التي قد تحتاجها لكي تعمل ... نعم يمكن أَن يكون هناك فايروس في جهازك ، ويمكن أَن يختار لنفسه إسماً يشبه svchost. exe .. ووجوده بجهازك لا يعني بأن جهاز مصاب بفايروس. . لأن أي جهاز يعمل بنظام ويندوز xp سيكون به أكثر من أو 5 نسخ من svchost. exe لكي يشغل برامجه . الوحيدون الذي لن يروا svchost. exe هم أولئك الذين يستخدمون win9x لأنه غير موجود بهذه الإصدارات من ويندوز .
ومن المضحك أن تشير بعض المنتديات إلى وجود فيروس خطير فقط لأنهم وجدوا svchost. exe، مما يسدفع الناس الى الاعتقاد بأن svchost. exe ما هو الإ فايروس مدمر أصاب جهازه . لتتأكد من خلو جهازك من وجود فايروس عليك باستخدام أحد البرامج مثل adaware فهو برنامج

The Svchost.exe file is located in the %SystemRoot%\System32 folder. At startup, Svchost.exe checks the services part of the registry to construct a list of services that it must load. Multiple instances of Svchost.exe can run at the same time. Each Svchost.exe session can contain a grouping of services. Therefore, separate services can run, depending on how and where Svchost.exe is started. This grouping of services allows for better control and easier debugging.
Svchost.exe groups are identified in the following registry key:
The registry setting for the two groupings for this example are as follows: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Svchost:
Netsvcs: Reg_Multi_SZ: EventSystem Ias Iprip Irmon Netman Nwsapagent Rasauto Rasman Remoteaccess SENS Sharedaccess Tapisrv Ntmssvc
RApcss :Reg_Multi_SZ: RpcSs
Svchost.exe groups are identified in the following registry key:
HKEY_LOCAL_MACHINE\Software\Microsoft\WindowsNT\CurrentVersion\Svchost
Each value under this key represents a separate Svchost group and appears as a separate instance when you are viewing active processes. Each value is a REG_MULTI_SZ value and contains the services that run under that Svchost group. Each Svchost group can contain one or more service names that are extracted from the following registry key, whose Parameters key contains a ServiceDLL value: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Service
To view the list of services that are running in Svchost: - Click Start on the Windows taskbar, and then click Run.
- In the Open box, type CMD, and then press ENTER.
- Type Tasklist /SVC, and then press ENTER.
Tasklist /FI "PID eq processID" (with the quotation marks)

Windows errors related to svchost.exe?
The file svchost.exe is the Generic Host Process for Win32 Services used for administering 16-bit-based dynamically linked library files (DLL files) including other supplementary support applications.
As operating systems became more complex Microsoft decided to run more software functionality from a dynamic link library (DLL) interface. However DLLs are unable to launch themselves and require at least one executable program, i.e. svchost.exe, is needed to bridge between the library process and the operating system.
Through the solitary file svchost.exe, the DLLs efficiently contain and dispense Win32 services as well as neatly facilitate the execution of svchost.exe’s own operations. Acting as a host, the file svchost.exe creates multiple instances of itself. The multiple executions of the file svchost.exe contribute to the stability and security of the operating system by reducing the possibility of a crashing process that causes a domino effect on its neighbor processes, thereby creating a system-wide crash in the machine. We strongly recommend that you run a FREE registry scan to identify svchost.exe related errors.
Other instances of SVCHOST.EXE:
1) svchost.exe is a process registered as a backdoor vulnerability which may be installed for malicious purposes by an attacker allowing access to your computer from remote locations, stealing passwords, Internet banking and personal data. If unaccounted for, this process should be removed immediately. Click here to run a free registry scan now.
2) svchost.exe is a process which is registered as a trojan. This Trojan allows attackers to access your computer from remote locations, stealing passwords, Internet banking and personal data. This process is a security risk and should be removed from your system. Click here to run a free registry scan now.
3) svchost.exe is a process belonging to Microsoft Service Host Process. This could also be a stealth monitoring software that sits in the background and tracks all activities such as keyboard input (including websites visited, passwords etc.) This information can be sent to third parties through email or ftp uploads. If you did not intentionally install this program make sure you remove it to protect your privacy. Click here to run a free registry scan now.

Svchost.exe Virus Guide
Some people report a single instance of svchost which takes up 99% of their computer’s resources – meaning a dead stop for everything else. What’s worse is that when there are multiple instances of svchost they are often competing for the same memory space, meaning none of them get to finish what they are trying to do, and neither do you! Before you take the steps to repair svchost, it’s a good idea to understand how this program works and what it does.
The svchost file is required to run these files as there is no executable. The .dlls called by the svchost executable could be for automatic updates or other legitimate programs, or they can be used to mask less benign programs.
Since there are many different services required by your computer there could be several instances of svchost.exe running on your computer, and they could all be taking up different amounts of your computer’s memory. A problem tends to arise when one .dll can’t complete its task, which in turn bogs down the rest of the svchost programs. Unfortunately, the svchost.exe is used as a favourite access point for viruses and other malicious programs, especially with Windows XP which has had serious issues with svchost in the past, although most of these issues have now been patched.
However, if you see instances of svchost it is a good idea to run a virus scan, just to be sure that nothing has crept in. Usually you will have a good indication that the svchost.exe is masking a virus or some other major problem when it is using 50% or more of your computer’s resources. The svchost can also become corrupted and cause problems when you install and remove programs, which shifts around the .dll files. So what do you do to fix svchost? While it’s a good idea to download a good registry scanner, you may want to do some more investigating to find the root cause of the problem before you begin.

Svchost is a shell program that is used to run many different services on your pc.
