What is Svchost.Exe?

Svchost.exe is an integral part of Windows OS, and provides generic host process for Win32 services. It cannot be stopped or restarted manually. This process manages system services that run from dynamic link libraries (files with extension .dll). Examples for such system services are: Automatic Updates, Windows Firewall, Plug and Play, Fax Service, Windows Themes and many more.

Svchost.exe is a process on your computer that hosts, or contains, other individual services that Windows uses to perform various functions. For example, Windows Defender uses a service that is hosted by a svchost.exe process.

At startup, Svchost.exe checks the services portion of the registry and constructs a list of services that it needs to load. Under normal conditions, multiple instances of Svchost.exe will be running simultaneously. Each Svchost.exe session can contain a grouping of services, so that many services can be run depending on how and where Svchost.exe is started. This allows for better control and debugging. You can use Task Manager to view which services are running under each instance of svchost.exe.

The svchost process was introduced in Windows 2000, although the underlying support for shared service processes has existed since Windows NT 3.1.

If you install a program and begin receiving notices that Data Execution Prevention (DEP), a security feature of Windows, is closing svchost.exe or other Windows processes, the cause could be services or extensions created by the program. Check with the publisher of the program to see if there is an updated, DEP-compatible version available, or try uninstalling the program.

Svchost is essential in the implementation of so-called shared service processes, where a number of services can share a process in order to reduce resource consumption. Grouping multiple services into a single process conserves computing resources. However, if one of the services causes an unhandled exception, the entire process may crash. In addition, identifying component services can be more difficult for end users. Problems with various hosted services, particularly with Windows Update, get reported by users as involving svchost.

Causes of Svchost.exe errors

Because svchost.exe is used as a common system process, some malware often uses a process name of svchost.exe to disguise itself. The original system file svchost.exe is located in C:\Windows\System32 folder. Any file named svchost.exe located in other folder can be considered as a malware.

Determining the image path of a process, and its invoking command line, can help identify software masquerading in this way, and help locate the actual program file which is running under the assumed process name of svchost.exe. Some malware inject a .dll file into the authentic svchost process, for example Win32/Conficker worm.

If the process svchost.exe uses high CPU resources, it sounds like a virus is attempting to start up a new SvcHost.exe and use that new instance to run itself and attack. To know exactly what is going on with your operating system, please try to use DLL TOOL to check your pc to find such malware.

Worms like MS-Blaster target a bug in svchost.exe. It sends a special packet. The packet has to be formed especially for 2K or XP and, if it sends the wrong one to your system, causes svchost to crash, which can force a reboot or make you lose copy/paste functionality.

The real thing is a critical OS piece that may legitimately need to perform an Internet request on your behalf. It is also a common name for malware to try to masquerade. If you have problems with this file, shut down, take a few deep breaths, when the PC is about ready to load Windows again, start tapping F* to boot in safe mode without networking. Search for all files named 'svchost' and delete any outside system32. Shut down and do a normal boot
