Information about svchost.exe file


File: svchost.exe
Name: Host Process for Services
Product: Windows
Manufacturer: Microsoft
Risk factor (Virus/Trojan/Spyware): Rating

"Svchost.exe" (Generic Host Process for Win32 Services) is an integral part of Windows OS. It cannot be stopped or restarted manually. It manages 32-bit DLLs and other services. At startup, Svchost.exe checks the services portion of the registry to construct a list of services that it needs to load. In normal conditions multiple instances of Svchost.exe run at the same time. Each Svchost.exe session can contain a grouping of services, so that separate services can be run depending on how and where Svchost.exe is started. This allows for better control and debugging. More info More info

Note: The svchost.exe file file should appear only the C:\Windows\System32\ folder. If you happen to find this file in a different folder, it is possible that your svchost.exe is in reality a malicious file. Many trojans and viruses try to cloak their real identity by using the names of legitimate files. Any time that you encounter a suspicious process, you should verify the digital signature and the file path, for example using Anti-Spy.Info.

Virus with same name:
Symantec Security Response - W32.Welchia.Worm

RatingDiese datei wird häufig als serv-u benutzt ich
RatingWorms like MS-Blaster target a bug in svhost.exe. It sends a special packet. The packet has to be formed specially for 2K or XP and, if it sends the wrong one to your system, causes svhost to crash, which can force a reboot or make you lose copy/paste functionality. Svhost itself, though, is NOT a virus. A virus wouldn't announce itself with a nice error message stating its name. Troy
RatingDisabling unneeded services will reduce the count of these.... It is exactly what it says... loads a service dll into memory... you can block or allow external or local traffic depending on exactly what service it is running, you might not want to allow traffic for some of these, but you may want others, danger level depends on what it is loading and what access is allowed by your security software and settings  link for more info Jason

Ratingcaused major problems with windows XP not loading correctly
RatingMS says this is a generic server that handles interprocess communications. It can load multiple instances of itself to hand bundles of related processes. It is an ideal alias for trojans, worms, and viruses. To see what processes use it, use the "Run" button and bring up a DOS terminal and enter "tasklist /SVC." Dr. Dee
RatingI have 3 of them running. The are Local Service, Network Service, and System. I also get about 20 minutes online before the pc just shuts down. I run XP Pro on an old AMD Athalon 800, with no probs. This just started, so I suspect 2 of those are not supposed to be there.  link for more info Alan
Ratingaparently it is a vital process for Windows so its better to not mess with it. However sometimes it will act strange and start consuming memory, this has only hapened to me a couple of times then I ran an antivirus and since then everything has been OK A friend
RatingWhile it may be Ok if in it's correct location ie under System32, be very careful if you find it located in either Program files or Program Files Common folder. If in that location it is a worm. Jim
RatingYes, svchost's multiple copies (wierd) on my computer keep trying to access different servers. I use Zonealarm's firewall and thanfully it blocks these attempts automatically Qasim

RatingThis should be the Windows RPC service. It is also required by javascript and vbscript, so if you remove it, webpages and folder views will look strange and not work. Unfortunately there are several viruses, worms and trojans that either disguise themselfs as this file or actually use a security hole (RPC+DCOM) in the real microsoft file to take over control of it remotely. (the MSBLASTER worm is an example) Make sure you have the latest security patches from MS. (Why the hell did they make RPC a required system component anyway!?) Prophet

Ratingrun cmd and go tasklist /svc and you'll see all the apps this "service" is running laughing
RatingThis file is used for networking and communications! if removed or blocked by a firewall then there is no more internet connection and nothing will work. This program is very dangerous. It allows any DLL including AOL AIM and other programs to access its communication ports. My firewall has been picking up incoming connections on ports I don't even use and that would be considered spyware or virus. MS better get their act together with security or else they will have more lawsuits on their hands from companies being broken into due to a faulting communications program. We have no control!  link for more info BrainScanMedia.com
Ratingsvchost.exe is a brilliant execuatable that prevents your computer form being inundated with corrupt files and internet bugs. It does this by utilizing existing 32 bit DLL's and Norton antivurus code Boris Beckham
RatingWhat a little pest this thing is. First of all, is it scvhost.exe or is it svchost.exe? I've had a LOT of problems with this little file. Basically, scvhost.exe keeps causing 2 pests to recur on my machine. I can remove these pests using Pest Patrol, but they just keep reappearing, esp on windows startup. So I disabled the scvhost.exe under the Startup tab in the system config utility (msconfig) and this seems to have done the trick. Kevin Wilson

Ratingsvchost.exe when running 100% , it means you are in danger of being exploited at that moment. try to restart ur pc.. but only a matter of time your pc will experience svchost.exe 100% again. internet is full of hackers and worms. better have antivirus running when experience 100% of svchost. very common got trojan in ur pc already. this svchost.exe is very vunerable to exploit and attack. it is very lousy product when dealing with internet. andrew
Ratingthese file can be deny access to internet. must be deny, else your pc will got 100% load (you are being exploited, there are files being x'fered into ur pc under your nose) . if you force shut it down using 3rd party application, then your pc might not function properly, like what they said, auto shutdown in 1 mins (use cmd , type in shutdown -a to cancel that auto 1 mins shut down), or you might experience file explorer can't do copy , move... right mouse click got problem...etc.. weird sort of problem, at least the person who tried to exploit you failed. you still can continue to use interne andrew

RatingCritical System Process - LOL Jay Wad - you can avoid the automatic shutdown when that message appears. Simply type shutdown /a in the run box and the autoshutdown process will stop. Usually you'll find that you no longer have sound (or other capabilities). Svchost will run for MANY programmes, if you keep your sys clean with AV and Antispyware/Antitrojan scans, then you've nothing to fear. Gasur
Ratingmy virus scan finds and removes some svchost-caused trojan at least once a week and at most a few times a day. What's the cure? On-Access Scan mode. With a good firewall and a virus scan running simultaneously, this should not be a problem. Do not mess with svchost, as you may damage your computer or force it to shut down. svchost itself is not the problem, it's the virii, trojans, worms, etc. that mimic its name you need to worry about. Erika
Ratingsvchost.exe is sort of like rundll.exe except is for running some services instead of running DLL's.  link for more info Craig
RatingIt is a Windows file, but is annoying in that you can have multiple instances of it running and sucking up RAM resources. Don't try to end the process or you could end up shutting down your computer Barb
RatingI have 7 of these running on my computer..One uses more memory than explorer..Virus scans find nothing though...I only have one of this file in my computer when i search. Alan
Ratingthere are four files of the same name SCVHOST.EXE and they shoot up the CPU usage to 100%.This makes normal offline working also horribly slow. Added to this is the RPC error system shut down in 60 seconds. While spyware guys have their reasons, it is better if they realized that many of us use the computers for earning our bread working on the system (doing taks like editing and typing data) . So Please stop this cynical and sadistic kind of programmes. Rao

RatingI'm reading that this can run in multiple instances, it's running seven seperate times in my task manager and when I ran a search for tis exe It only comes up in two places: c:\windows\system32 and c:\windows\servicepackfiles\i386 ...something aint rite here!
RatingAll I know is it slowed my computer down and my spyware identified it as malware. My computer techy deleted it from multiple locations in the drive and in the directory. I hope this works. It renamed itself in my windows temp folder every time I restarted the computer. Starlite
RatingDependent on it's location, it's either a genuine part of the operating system (ie it's in c:\windows\System32 folder) - otherwise it should be deleted. I recommend that the registry editor is used to search for references to any other instances of this file, and those references deleted. Leave the genuine file alone, though! Wobbledoggy
RatingThe 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. Goyo
RatingThis file is not dangerous if signed by microsoft corporation. but there are copies out there that may be a viruse. Everytime I boot up my cpu is at top (97-100%) and its only one that are hogging, its svchost.exe. I have stopped it but it keeps starting up in every bootup. For the time, I just have to spend 70 seconds (takes long time with 100% cpu to get up the task manager) to stop it from taskmanager! I do not like this process and want to KILL it! but, no way to do that! Lars89
RatingI have three versions of svchost.exe (system) running in task manager and one of them is always above 35,000kb and each time I end the process it comes back. I just ran Symantec Virus scan and it says I have 6 detected viruses all of which are in svchost.exe(system)... Randy Lahey
Ratingsvchost.exe is harmless. It's just used for hosting programs / information. If you have a virus that appears to be svchost.exe, it is most likely a virus using the name svchost.exe. It does make copies of it self, however it only did this when I pushed my PC to the limits of memory and hosting. Pete
RatingIt tends to get infected pretty regular in my experience. Another badly designed file. Sphinx

RatingI too was having the 100% cpu usage problem whenever I started up IE. My problem also may have been linked to indexing. I switched 'DNS Client' to manual using the XP component services manager and now I have no problem. I suspect the CPU usage thing may be more a software than malware problem--potential XP service pack 2 glitches. John

Ratingc:\windows\system32\SVCHOST.EXE is a VERY important file required for the proper operation of your Windows. Some of the links already pasted will give you details on why it is so critical. Now if you have a file with the same name 'SVCHOST.EXE' in a DIFFERENT FOLDER, any other folder apart from system32, THEN and ONLY THEN could it be a cause for concern. So just run a file search on the file on all drives including all system and hidden folders, and if you find any instances of this file in any folder other than windows\system32, then delete it immidiately. Mr Duckk
Ratingi don't much about this file but i agree that it affects your CPU usage. I tried to disable one of them since i was running a couple, and it shut down my computer...
Ratingif it gets on to your internet files it doesnt' let you to go on some web sits
RatingAbout 100% memusage:It is most likely the rpc worm. If you didn't have a service pack installed, your system would've bootd automatically, but because of your service pack installation, this msblast worm will just reserve 99-100% of one of your svchost.exe. You have to go and apply a patch KB823980 (msblast). You can google it e.g. "index of" msblast - 1.2MB file called WindowsXP-KB823980-x86-ENU.exe for xp at least should do the trick. If you are patient, you could go find it from the mazes of microsoft.com too. There is also a virus called scvchost.exe in addition to those already mentioned Ville N

Blast has the same names in different directories... i stuck with that virus i dont know what do to, i formatted my comp about 5 times... and its still there, i didnt even connect to the internet and i saw the Svchost.exe on task manager, I do end process or end process tree and i it shows the "shutdown
Ratingi have two of them running on my pc when searched i get only one
Ratingi have 5 or 6 on my cpu... it doesnt slow it down at all! i have an AMD athlon 2400+ and this process never slows it down the slightest, my computer used to be slow... but i cleaned up all the spyware and it sped up alot... also most spy ware programs dont pick up all the spyware... make yourself a list of all your running processes then investigate the folders they are in and their signatures which usually give you alot of hints as to what should be running and what shouldnt. my computer runs at about 0-4%. and regularly check the processes that are running to make sure you dont have anymore. mick from australia
Ratingi deleted it svchost, but in need. how do i get it back Brown
Ratingit needs to be on my computer jon domico
RatingIf your system is slow it is not because of svchost. It is because you have spy/ad ware, you are trying to runn to many apps at once or because your system just plane sucks. The majority of the people here say to leave svchost alone, so... JUST LEAVE IT ALONE. kikoku

Ratingalright, ive got 4 going, and my pc is suing 3 % of its usage percentage, therefore svchost.exe is a safe file Chris
RatingUses 100% of CPU and blocks other pending operations. When I stop this svchost.exe my processor occupation goes straight down to normal level and my PC works normal again. Evert
Ratingif your runing XP and svchost.exe is in c:\windows\system32\svchost.exe leave it alone, but if your on any other OS make sure you delete it might be a IRC backdoor used to scan/upload to other peoples pc.

RatingIf it needs all your CPU usage, then go into the Taskmanager, right click it and end it. Then the PC will shutdown in 60 sec. To stop that, you need to press start, run write cmd. Then a Dos window appears and you can write shutdown. Then it will stop and you can go on. The link below is in german!  link for more info Martin
RatingNormally safe but can represent a disguised parasite. To prevent shutdown after ending this process, in CMD prompt run 'shutdown -a' Marcus
RatingIt stands for Services Host. I have 3 instances of this file running, 1 is in Local Service and 2 are in Network Service. But as I know what it is I will share it with those of you who are getting worried. The process in Local Service Is my System, The other 2 in Network Service are my other 2 systems which are networked therefore 3 systems on a network 3 Services Host Processes. 1 svchost per networked user. See, not that difficult. As always, if in doubt close it, but you WILL lose network access and your system may become unstable Si UK
RatingDie Datei benötigt über 25000kb, wenn ich versuche sie zu deaktivieren erscheint eine Warnung das sich der Computer in 1 Minute abshalten wird. Ich kann keine neuen Datien Installieren und die CPU Auslastung steigt manchmal auf 100%. moses

RatingEverytime I start my computer, appears a message that says "svchost has generated errors and will be closed by windows" I was opening the task manager to stop it but now I can't open the task manager Davin
RatingThis file really fadeup me, cuz its slow down my system speed, and some time it irriates me too much when its disable my copy paste option ,and all the time i have to restart my system Nida
RatingIt hosts multiple services, and it seems to fork multiple copies of itself to handle those services... ok so far nothing wrong with that. But now I've seen a weird 'jerkiness' problem when playing movies or games, and one of those svchost.exe processes jumps to 100% cpu momentarily... it is also using a lot more memory than the others. I havent yet discovered if this is a virus installed as a service, or just some badly written service that got installed as part of some other junk.... Neko
Ratingsvchost lstet die cpu zu über 90% aus und bremst daher mein system ungemein aus und es lässt sich nicht deaktivieren da Windows sonst innerhalb von einer Minute herunterfährt ich habe bisher kein Programm gefunden durch das sich dieses Problem beheben lies Hell
RatingStop complaining about symptoms and start looking for causes. svchost.exe cannot be deleted. use task manager and show the PID, then use tasklist/svc to identify which services are using the PID in question. My 100% usage was being caused by my DNS Cache complaining about using a large hosts file. I disabled the DNS client service and the problem is gone with no side effects. This was nothing to do with svchost.exe rather the service that svchost.exe was called to use. Ben
RatingIt is not spyware or a virus if it is in Windows/System 32. Don't block it! If you block it, some programs might not work (including Mozila Firefox). I don't know why it used 100%of the CPU because it didn't on my computer. I will respond again if I find out. It is not bad if there is more than one running. For XP, follow the link for more info.  link for more info Pi
RatingThis is taking up 100% CPU memory at times and you couldn't really tell between the fakies and the real. A real headache! Have formatted my PC twice!
