• Someone at - it a repair for a function that is usually common in Windows, the Svchost.exe process? I and many other users of PC have infested with this mystery bug. Its not to damage yet, but...

  I'm infected w / which seems to be the most mysterious infection known for Windows right now.  One wonders if it's a Trojan horse, worm, malware, etc., or just a natural process for C: Windows\system32.  It's almost like 'shadow people '.  For most, there quite harmless, fantasy of the mind.  But, from time to time, there is actually something that happens on the corner of your cornea, so to speak.  This is very sneaky and difficult to diagnose a problem b/c he hides with the Service host.  I'm here b/c I have a question, but also to help others to understand that, unlike the 'shadow people', the shadow of an infection is very REAL.  This infected process is, for the most part, quite harmless unless something malicious attaches to it and could things get a bit risky.  Anyway, I'm sorry for this rambling diatribe, but I have a question for someone who is very smart b/c so far it seems not yet to be a definitive repair because some people still think it's a natural function or process in the Windows operating system.  So here it is: How can I solve this problem?  And I can fix it with or without a full restore of my records?  I'd really appreciate any input on this very discouraging, boring, mind and body draining, faulty computer "BUG".  BTW, I have a dv9500 HP Pavilion x 64 Ultimate for Vista that was bought there are 3 1/2 years.  I've dealt with this infection since the end of February and have spent more than $400 on this terrible nuisance.  But Club (all jokes aside), I really enjoyed, grateful and very thankful for someone with an answer to this complicated issue.  Thanks for the time!

  After installing Windows 7 with everything working well, I started now get frequent (every few minutes) drive activity periods that are so intense that I can't do anything until they stop.  I tried to disable services (indexing, superfetch), my pagefile is set to automatic and the memory usage is only 50%.  I even uninstalled Norton Internet Security 2010 to see if it would eliminate the beating.  Even with only a single program running (I tried IE, Opera and Firefox as the browser), I still have this problem.  Nothing seems to stop it.  I'm going to uninstall W7 and go back to XP.  Any suggestions?

  If you need search malware here's my recommendations - they will allow you to

  cause.

  No one program cannot be used to detect and remove any malware. Added that often easy

  its best to be thorough than paying the high price later now too. Check with them to one

• Svchost.exe takes the largest part of the allocation of bandwidth per month

  I have nine copies of svchost.exe running on my computer and one of them seems to be still using 10-20% CPU. Looking at using my BTsoftware, the active svchost.exe is listening on multiple ports, including 1900 several times and often transmits the data in my Home Hub and possibly to the Internet using port 8000. If I stop this process, it rebuilt after a short while and goes back to what he was doing. If I look at traffic analysis, it is often to 96% of distribution during the last 24 hours. Any ideas gratefully accepted.

  First, you must be reasonably sure that you are free of malware.

  No matter what you use for malware protection, follow these steps:

• I have a svchost.exe in the processes that CPU load in WinXP.How to control this?

  Process / task manager has a svchost.exe thatreally slows down and sometimes crashes my computer. Windows XP Media Center Edition with

  SP3. Is there any solution for this?

  It is usually associated with the Services.  One instance of "svchost" can support multiple services.
  The first step is to download and run the "Process Explorer" from Microsoft
     <>http://TechNet.Microsoft.com/en-us/Sysinternals/bb896653 >
  This program is the the Task Manager on steroids (once you try it, you'll never go back to the Task Manager).  Once you start, you should have no trouble to identify which instance of "svchost" consume all your CPU.  When you do this, place your cursor on this "svchost" in the process column.  A pop-up menu lists the services that are currently covered for this instance of svchost.

  New commissioning Services (start-> Run-> "services.msc").  Find running services that correspond to the list that you obtained in the previous step.  A double click on this service will give you a screen that will allow you to Pause or stop this service.  Try to stop the appropriate services until you see your CPU down to normal.  This will determine what service is the consumption of the CPU.  How you handle this from here will depend on what you find.

  (As a side bet, my money is on the "Windows Management Instrumentation" service.)

  To help understand your processes svchost.exe and what is running under them, read this article and you will be smarter than the average bear:
  http://www.bleepingcomputer.com/tutorials/tutorial129.html

  You may be able to get clues with what is happening with your svchost.exe process using the Task Manager and maybe understand.

  You will always be able to understand what is happening with your svchost.exe process if you use Process Explorer.

  Download Process Explorer, so you can see what is 'really' running on your system, especially behind those svchosts several process see you in the running task manager.

  Download Process Explorer from here:

  http://TechNet.Microsoft.com/en-us/Sysinternals/bb896653.aspx

  You'll like Process Explorer when you get the hang of it.  Process Explorer is the Manager of Windows taskbar on steroids.

  Process Explorer installs nothing so it won't slow down your system since it works only on request.

  Process Explorer can seem a little intimidating at first because it has so much information, but you will begin to make love the way it works when you're looking for performance problems.   You can even say EP you want it to be your new default 'Task Manager' value in the future.  You can always run the original tasks as Manager.

  Once you get Process Explorer running, expand the columns, made drag the corners of the screen for it's largest, etc., so you can see as much information as possible in the window.  Now you can really see what is running on the system.

  Here's a screenshot of my poor system when I use Process Explorer:
  http://img222.imageshack.us/img222/2567/ProcessExplorer.PNG
  The CPU column is usually the most interesting start with performance issues - which uses the most?

  It is OK and normal to have several svchost exe processes running.  Important XP Services are actually running under svchost.exe processes. There are sometimes an XP Service that runs under a svchost.exe process, sometimes there are several Services in XP, which runs under a svchost.exe process.

  Sometimes malware will hide behind a svchost.exe process because the malware knows that you won't be able to find it in the Task Manager.  He will hide behind a svchost.exe process to deceive you, but you can outsmart it.

  Malicious software can disguise itself also seems to be a legitimate process of XP or he could hide under/behind other processes that you see running in Task Manager if you can't see the execution.

  The malware would trick you into thinking you must use a System Restore Point, run a repair install or reinstall your XP from scratch when you really don't.

  Looking at the display in process Explorer, you want the CPU most to be associated with the system idle process.  It's 'free time' on your system, so more time there, more free.

  If you look at the graphs of performance and see red spikes (or not) double click the graphic in the upper left corner to display the graph to use.  Move the mouse over any pics to see what are the causes.  Even if the Spike has already scroll screen, you can still move the mouse over the edge to see what caused.  You can also just wait for a pic to happen and then see what caused the Spike.

  If you think one of your svchost.exe process is out of control or run amok, understand that some malware will hide as a process behind one of your several svchost.exe processes.  All what you will see in the Manager of tasks is a svchost.exe process that has run amok.

  The malware knows that you won't be able to see it in the Task Manager.  The malware hope you will do something drastic like use a Restore Point, perform a repair installation, or even to reinstall your XP from scratch.

  No matter what you use for software malware, detection and removal do this first:

  Download, install, update and do a full scan with these free malware detection programs:

  Hi MarkBerri,

  ·         How long have you been faced with this problem?

  ·         Did you do changes on the computer before the show?

  Svchost.exe is a process name generic host for services that run from dynamic link (dll) libraries. The Svchost.exe file is located in the folder C:\Windows\System32. At startup, Svchost.exe checks the registry services part in order to build a list of services that it needs to 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 enabling better control and easier debugging.

  Svchost.exe groups are identified in the following registry key:

  HKEY_LOCAL_MACHINE\Software\Microsoft\WindowsNT\CurrentVersion\Svchost

  You can run the auditor of system files on the computer.

  Application error - svchost.exe Instruction at 0 x 0000000, memory could not be 'read '. My PC crasches is frozon

  You must identify which application was using svchost.exe when the error occurred?

  What you were using at the time? The error occurs on a regular basis? How long between errors?

  Take a look in the system and Application logs in the errors and warnings event viewer and post here the copies. Do not post on that more than 48 hours ago.

  You can access event viewer by selecting Start, Control Panel, administrative tools, and Event Viewer. When searching for the meaning of the error, information about the event ID, Source and Description are important.

  A tip for posting copies of error reports! Run Event Viewer and double-click the error you want to copy. You will see a button resembling two pages. Click on the button and close Event Viewer. This places a copy of the report to your Clipboard. Paste it into the body of your message. Make sure that it is the first dough right out of the event viewer.

  It is always sensitive in this situation to achieve a malware check.

  Download and install Malwarebytes (free version for individuals only), updated definitions and run in safe mode. Disable other security software while you do the analyses.

• unusual internet connections of svchost.exe

  When I boot into windows 7 I noticed svchost.exe making multiple connections to the internet

  UDP on 8.8.8.8:53

  one of the connections that I know is my dns server
  the other 2 I'm not sure, seems to be a microsoft ip and the other is a hotmail IP
  is this normal for svchost to connect to these ips?

  I thought it might have to do with updates of microsoft, but I turned it off, never looking for updates, but it still connects to these IP addresses.

• Svchost.exe causing 100% cpu usage during the update of windows, even when disconnected.

  I recently had to re - install windows xp on a new hard drive for replacement. My version of xp home edition, SP2 OEM installation disc. (This is ith group included IE6)

  Once installed and running, could access windows update.

  Read all the threads associated etc. and installed SP3, disc after downloading microsoft on another pc. Installed after three trys, first two caused various mistakes, but third attempt seems OK!

  I've also updated the IE6 to IE8, as some sites obviously did not work properly with the older browser.

  Now go do the automatic updates, or log for manual updates... BUT!

  During the process, my cpu fan comes on fast and permanently! The CPU usage is showing that 100%, pc slows to crawl, the mouse becomes slow etc.

  This has never happened before on this machine before you reinstall clean, he had already automatically updated to SP3 and went very well, it was some time ago, before the failure of hard drive, and it has never had this problem!

  Only since having to do a cleaning manual update and re - install.

  The culprit seems to be svchost.exe, once it is used by the update, running the cpu at 100% and continues to do so EVEN after stopping the service, until I manually stop with the Task Manager!

  The svchost.exe instance showing a high is use: SYSTEM.

  According to the files of help here, it is a known issue and a fix KB927891 was issued for SP2, but this should NOT be necessary for SP3, and in fact difficulty used to perform anyway under SP3!

  Ideas for a guy to fix?

  I appreciate the support for XP runs out quickly, and after this update of windows will be redundant, but in the meantime it is always useful!

  Also if I turn off the automatic updates, how can I stop this annoying popup warning bubble?... I can't live without updating, but this bubble nag drives you nuts! :)

  OK just a update, now running cool and 100% auto update and manual update... How? I hear you ask...

  Well I had a beer and a reflection and came to the conclusion, it must be 'order' in which I updated the clean installation of XP.

  Origin, I loaded the old OEM disc new hard disk, loaded the drivers etc, then stop at windows update for updated files.

  Who told me my old incompatible browser and suggested an upgrade.

  I downloaded and installed IE8... still no joy, reading the forums comments I downloaded and installed SP3... which SEEMED to work, BUT then all the hassle of cpu to 100% with the automatic update and updated manual on the windows don't update site!

  So I just gritted my teeth, formatted the drive, another OEM of XP Home Edition SP2 installation loaded the drivers, installed a copy saved to SP3 and after restarting, THEN installed a saved copy of IE8 and THEN trotted off the coast to the windows update site... low and behold, it the connection without problem, did a search, and required updates appeared on the screen without delay all 123 of them...! :)

  Did the updates, restarted and everything was fine, updates automatic in market and left the machine, after about 30 minutes appears the yellow shield, and it downloads a couple more update files without problem.

  All this time I followed the via the Task Manager CPU usage and the strange spike waited 100% apartment, it was on average from 5 to 20%!...so a great improvement has this effect, by simply changing the order of the updates installed from the original! SP3 IE before IE8.

  May not work for all have to do a clean install because of the HD failed, but its worked for me, and I am once more a "happy bunny!
