It's a network service by Windows
My laptop locks. I use my task manager and see my cpu usage is up to 100% with svhost at around 99. I use task mgr to shut it down and this takes care of my problem

my file is missing how do i reinstall

ya It also a network service of windows
windows process is svChost.exe, not svhost.exe. It's tricky, but you have to watch for the absence of the 'C'
Svhost.exe IS malware.. not to be confused with Svchost.exe or svchost.scr ... tho svchost.scr is malware.. cuz I was fussin at boyfriend tellin him he was wrong.. so yeah.. and its a pain to remove.. i had a program that scanned my pc and found it.. tho couldnt delete it.

Spoof of an essentiall network service. It's a virus.
It's an infection. It bears a similar name to svchost.exe, which IS a vital program.
Ape, you are thinking of svchost. (the other is missing the c)
svhost.exe in C:\Windows\System folder is definitely a virus. Associated with 66.scr or most any other .scr that gets loaded to the hidden network services folder. This virus has taken control of pc's, cloaked stnetlib.exe virus, activated a: drives, virus autoloads to A: drives or USB drives, all hidden files, LUCKELY as of today March 30th, AVG antivurs updates locate and stop this problem.
After killing the process and deleting the file, it kept reappearing in Task Manager. I did a search for "svhost.exe" and did not find any file anymore, but it was still running (according to task manager). The ONLY way i managed to stop it was with Sunbelt Personal Firewall, by enabling Application Behavior Blocking and configuring for svhost.exe to deny: starting, modifying and starting other applications. It's still there I think, but now it';s being kept under control.

It is S-V-Host, not S-V-C-Host! SVHOST is known malware! SVCHOST is the generic Windows services host process!! REMOVE SVHOST!
My experience shows c:\windows\system\svhost.exe generates .scr usually named 01 -86.scr files in system32 folder. They do produce a lot of network traffic similar to conficker.
ran across it myself.use cacls svhost.exe /p guest:N to disable access to the file
It is not to be associated with svchost.exe. Easily found and removed with maleware bytes.

Trojan. Beware SVHost versus SV-C-Host. If it doesn't have a C, Trojan.
my svhost.exe is in C:\win32 and there is only that file(Crashes my pc sometimes/virus)
Welp, didn't realize it's a virus. Was using 46% of my CPU, not to be confused with svhost.exe
Drove my Graphic Cards Usage up to 99%. While playing I noticed an FPS drop, so I got suspicious. Found out it was svhost.exe. What I did was preventing it from running. Google for:"prevent programs from running" or use the link attached.

Best practices for resolving svhost issues

A clean and tidy computer is the key requirement for avoiding problems with svhost. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the svhost.exe process on your computer, the following programs have proven to be helpful: ASecurity Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. BMalwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
