• netsvcs svchost.exe using too much speed processor - Windows 7

  Hello

  My laptop that runs windows 7 works very slowly if at all during startup or even to open programs. I open the Task Manager > performance > resource monitor and find svchost netsvcs uses more than 90% of the CPU. I found by suspending the process of that CPU usage falls considerably to about 12%. I tried searching, but am not very computer. I installed, updated and scanned with malwarebytes, essentials of microsoft. I came across a thread, which suggests HijackThis, I ran, but I'm not sure what to fix and what not to do. Here is the log:

• Svchost.exe netsvcs paralyzes my computer

  I am running windows 7 on an HP Pavilion age of 1 year Entertainment PC. Recently, my computer started running a lot slower and hotter spasms. When I study with Windows resource monitor, it always seems to be a version of svchost running at almost 100% of my CPU usage. It usually seems by svchost.exe (netsvcs). When I try and put an end to the process always restarts immediately and goes back to grab my resources. The last time I tried just hanging in and my shockwave plugin crashed into firefox, until I got it. Another that I'm not having any luck correlating the process to any specific program. even when I've yet to open any program that he often sits is almost 100%. I use Norton anti-virus and have tried to run a virus scan, but he did not find anything. Help?

• (fontcache) Svchost.exe using 99% cpu

  Hi, I'm running Windows 7 Ultimate x 64. Randomly, the svchost.exe (fontcache) service will start using 99% of my cpu, everything a lot. Specifically, it starts happening when I play Team Fortress 2, but it also happens while I play the game. During a match, making the game lag, giving me a very large ping 2000ms + and no fps. If I end the process, it stops and is fine. But it could be the cause?

  Common programs, I have running at all times are as follows:

  AVG anti-virus

  Pidgin (AIM client)

  Skype

  Google chrome

  Windows media player

  Any help would be great, it becomes annoying random having my computer be bogged down for no reason. Let me know if you need more information

  Thank you, xJedix

  Hey guys, thanks for the suggestions.  Actually, I found another person who had this problem.  Their solution was to remove the additions of the shell that nvidia added to when you right-click on the desktop and things.  This has solved the problem, at least until now...  It's 3 days now without problem and also fixed my problem Explorer.exe crashing several times when I was reviewing the files :)

  If anyone is wondering how to disable programs that have been added to the hull, use shexview.

• SVCHOST. EXE using 100% CPU

  I have a Pentium (R) 4 CUP 2.4 GHz running Windows XP Home Service Pack 3 5.1.

  In the last month, I updated my virus software - ZoneAlarm - and downloaded Google Earth.   Meanwhile, there was also many windows updates automatic including IE8.   Since the download of the update to ZoneAlarm I have the BSOD a few times (the BSOD said ' corrupted driver MMMPOOL or similar) but after reboot it was fine.

  We had a few fluctuations in power a couple of days but the computer is connected to the battery of emergency relief so has been closed properly.   When the power was restored properly the computer started and the BSOD came once again.  You had to reboot a few times in safe mode, and then selecting the option "last settings that worked.  Since then, every restart was fine (no BSOD).

  I ran a full scan, update ZoneAlarm for updates.   It is a Trojan horse that he deleted on reboot.  However, everything was very slow and firefox who previously worked very well kept freezing.  Outlook Express has been extremely slow.   IE8 was still slower than firefox.   I've updated to the latest version of Firefox, but no improvement, or worse!

  The Task Manager showed the CPU usage to 100%.

  Then I ran a CHKDSK and defrag because it had not been for some time.

  After that, the CPU usage is 100% yet once (I dunno what I used to take me to check this again.)  A SVCHOST. EXE program was the culprit to 99.   I finished the program and it came with a warning message indicating the process server Launcher DCOM had been canceled and the system has been restarted.   The PID of this program was 868.

  After a reboot, it seemed better.  I used Outlook Express OK, but as soon as I launched a browser, the CPU usage went straight to 100%.   Even if I close the browser, he remained at 100% and has remained there since.

  Online access is practically impossible on this computer, I use another computer to get help!

  Advice would be welcome.    Please note that I'm not terribly computer advice should be simple and basic English.  TIA.

  Remove the Trojan from your computer, it is stiil in your computer.
  Your computer will work normally.
  Your alarm zone anti virus program or fire wall only? or both?
  If you analyze the pc and the answer no viruses not detected.
  I swuggest you use another antivirus program by stopping zoenalarm temperory or delete, in mind that 2 anti programs antivirus at the same time on the pc will be a conflict, so you should disabel or one of them or remove.
   
  1. right click on the my computer icon go to System Restore then put a tik on judgment system for all stations restore, apply, then ok.
  2. complete the system scan and remove Trojan horse if you can find or put a carentien if you don't know what to do.
  3. restart the computer and see if it works properly and also run full system scan new .If it is clean your pc is now 100% clean of the Trojan horse.
  4 after 1 or 2 days also scan your computer and then repeat step no.1 again by going to the system restore and yesterday to cancel the tik put you on the restoration of the system shutdown for all stations, apply, then ok.

  Good luck

• TosBtProc.exe using 100% CPU

  I have a Tecra with built-in Bluetooth 9100, running Windows XP SP2 however, everytime I turn on the bluetooth, using the system tray icon the TosBtProc process starts to use 100% of my CPU and pipes of my machine unless I kill the process.

  This problem was happening before that I updated to SP2, I tried upgrading to the latest v3.20.01 Bluetooth Stack but that made no difference.

  As a result, I can't connect my Bluetooth phone to my PC.

  Does anyone have ideas, what is the problem?

  Hello

  It's very strange. I have Tecra M1 and it resembles your T9100. I tried to go wireless and Bluetooth connection, but everything works fine. Can you please try the same thing using FN + F8? Use just the Bluetooth wireless as there is option that allows connections on the same time.

• Log file of NOD32 which can help diagnose the problem with svchost.exe, WScript.exe, mshta.exe and windefender and update please someone help does not!

  HHmmmm bears ok I will answer your questions, but I don't really see the relivence of them for the progs anti, spy, virus, malware are not the problem.

  (1) a little more than two or three weeks ago or not.

  2A) about two weeks ago.

  No. 2B) I don't buy anti progs that do not work. Why would I? He did not set the blocks just prob the random load IE 8 to a maleware site addresses.

  (3) I got the updated version of Avast for almost two years. He simply blocked addresses saying something was trying to use svchost and WScript mshta.exe to attempt to load IE to a maleware site. I disabled Avast but since the installation of NOD32 if she does not interfere.

  (4) I don't remember what I used before I think it's Norton or macafree but I don't know about two years ago, I had the computer taken, wiped and reinstalled windows and they gave me Avast for free.

  (5) Yes, I tried Norton and Macafree, and they do not work to correct the problem. I uninstalled them well and they are no longer on my computer.

  (6) no they were not preinstalled.

  If you're going to ask me to do a system restore it will not help I already tried. Useless program when you can't use it. I tried several times with different dates, even in safe mode. I already ran on Microsoft Live Onecare, MSRT, Fix and MSE. I have spybot, malwarebytes, superantispyware, synematic and have tried them all. Nothing can solve the problem. Now NOD32 blocks the random addresses loading IE but it is very annoying seeing this thing pop up constantly. The only thing that it does not stop is when I use IE occasionally it will load a location for a Wal-Mart gift card, but I've just close it. If I use a different prog or any it constantly blocks the random addresses loading IE. I don't have IE loaded. Yes I have popups blockers, but it does not block another page being loaded on the card gift wlmart site. everything else works well.

  Please don't give me no matter what more links to the help pages for Microsoft because I already looked through them all and tried a lot of useful advice and none have worked. What I really need Bear is a set of instructions on what or the files to search posibly containing a script that gives orders to the system files to try and load IE maleware sites. I need to know where to look, what I'm looking for and how to rewrite or erase the command or script. Probly get rid of some files HKLM or commands too if there are orders as well. I'm sure you'll tell me its probly in both registry keys. in any case if you can help with a set of instructions on how manually enter and take care of the problem that would be great.

  I have seen the manual of instructions on how to repair scvhost.exe but I'll not go messin' and delete this file cause I know that you need so that windows run. I'm sorry for the poor fools who go on Ehow and follow the instructions. in any case if you can help it would be greatly appreciated I don't have the money right now to put this thing in the shop with Christmas around the corner and all. Peace!

  bear oppss sorry I forgot to say of windows has been completely updated in time and yes I was able to connect to windows update and defender update as well before that happens, but now I cannot connect to a, but can connect to anywheree else apparently on microsoft or other juice of sites not not both.

• Csrss.exe pic 100% CPU for Win 2003 Server

  Hello

  Recently, I've migrated a physical server to virtual (Server 2003 R2 Std). After that, I see high utilization of the processor in the csrss.exe process.

  I tried to check in via Process Explorer. Csrss.exe displays as much CPU being picked up in Process Explorer as it does in the Task Manager window.

  I tried the below, without a bit of luck.

  (1) complete analysis of Ran. No Virus found.
  (2) removed corrupt profiles (http://support.microsoft.com/kb/555021/en-us)

  Sometimes, when I have connection I noticed my profile size is 4 GB.

  You guys can suggest me any solution to workaround to fix high CPU usage.

  The migrated VM is single processor

  When performing a cleaning disc and by checking the boxes to remove, do not delete atchived system and queued windows error reporting. How can this be repaired?

  Hello

  1. you are using a third party software to clean your computer?
