SVCHOST.exe Takes Up All Of The CPU Usage?
Mar 19, 2007
The computer is nonresponsive for the most part at first. I click on the start button and nothing happens, but if i click on any desktop items they become highlighted because I clicked on them, but if I try to open them, they don't open immediately. After about 2-3 minutes of doing nothing, everything that I wanted it to do happens all at once.
When I open task manager, the thing that is taking up all of my CPU is this thing called SVCHOST.exe; there are 5 of them running - 3 for system, 2 for network service, and 1 for local service. While the computer has an episode, one of these for the system will use 99% of the CPU. That is when things are nonresponsive and slow.

Soon as i turn it on the antivirus starts up and my broadband connects then it freezes, a few times i've managed to open the task manager and i notice that on the CPU Usage History it it constantly at 100% and when i go onto the Processes tab instead of System Idle it is SVCHOST.EXE that is using all the CPU.
I thought it was a virus so i started my PC in safe mode and run the virus scanner, it found 3 Trojan Horse Downloaders, one even named itself CMD.exe which i thought would of cured the problem but ive turned it on this morning and it is still the same, it seems a little better and lasts longer before crashing but it still crashes eventually.

checked windows task manager...it appears to be svchost.exe (not svchosts.exe). Is this a virus or spyware because i have 3 different ones on system?

Every time I'm on the internet svchost.exe takes up half my CPU. I can't browse, I have to constantly end svchost.exe so that I can sluggishly switch pages then in seconds it pops back again. Svchost.exe is somehow connected to my internet connection because i need it to use the internet yet its not letting me, its really frustrating, I've been beating my face on my desk because i cant figure out whats wrong. I've scanned my computer with AVG, malwarebytes, Spybot S&D, and Ad-aware.

I have recently become annoyed at the high memory usage of the svchost.exe process. I have 8 of these services running at the moment. I havent had reason to complain until recently when they seem to be using more memory than necessary. I might just be over reacting here but perhaps someone can verify it for me. I have included a hijackthis log at the bottom.my system is running WindowsXP SP2, Asus K8VSE deluxe, Athlon 64 3200, 1.75 GB RAM, updated via drivers and windows updates (except one that just came in and I havent done yet).These just seem like too much memory for these. I have check at blackviper and didnt really see a lot of things I could turn off. I could be wrong though.

Does explorer.exe and svchost.exe seems to be using a lot of memory,or am i just being paranoid?
Its not usually like this though:
I have also included an Hijackthis report:

I have asked this before, but on startup, I have several processes named svchost.exe that run on startup. One of these is a network service and every time, this particular one uses 50% +/- CPU. Apps will not open, nothing will function correctly until this is terminated.

Both svchost.exe + wuauclt.exe's memory usage occassionally increases rapidly even if my laptop is idle. I have to terminate wuauclt.exe manually (through End Process in Task Manager) in order for the 'Commit Charge' to return to late 300/early 400M figures. If my 'Commit Charge' is 5XXM or above, if I plug any USB devices Windows XP won't recognise them. I have to terminate memory consuming programs (e.g. Firefox), restoring the Commit Charge to 4XXM, then Windows XP will recognised any USB devices I plug in. However, if I plug any USB devices right at the beginning when I turn on the laptop, I won't encounter any problems. Why is this?

I'm running XP pro SP2. I have a gig of ram and my mother board is an Intel D101GGC. My CPU is Intel Pentium D 920.
If I use Windows Explorer to go deeper than the first level of any tree, CPU usage goes to 100% and stays there. I've disabled System Restore because it wouldn't let me go back in time anyway and this program is a known resource gobbler. Didn't help. I've attached a hijackthis logfile to see if anyone recognizes a Trojan, etc. I would appreciate any help at all.

when i start up this pc, it becomes very slow. I go to task manager and have a look and i see SVCHOST.EXE as a system process. But is Mem Usage is like 40,000 and it is taking up 99 on the CPU and the CPU usage shoots to 100%. I can stop this process and the start bar will look like the windows classic for a bit then change back to regular xp.
i have tried to google it and i see all sorts of things, like spyhunter etc. i have tried all sorts of steps to remove this but to no avail

Everything was running slowly, i press ctrl - alt - delete and wait 5 minutes for it to eventually come up, i then went to the processes tab and find that svchost.exe is running at 99% CPU I usually end process on that svchost, but then i cant connect to certain servers, and sometimes my sound drivers disappear also(not 100% sure, but this seems to be connected

When I start it, after a few seconds, a task is appearing in the Task Manager, called "svchost.exe", which is using 100% of my PCU. I know this task is part of Windows, but I'm wondering why it uses so much CPU... I performed a search on the web and found 2 tips: 1- Performing a registry scan (with RegCure or equivalent), then a spyware scan and a virus scan; 2- Updating my system on Windows Update. I did the first step with the free versions of RegCure and RegistryFix (registry scan), AdAware and AVG Free. But concerning the 2nd step, when I go on the Windows Update site, the automatic update tool performs an infinite search to find the suitable updates for my system

This has been going on for awhile. When I start my PC svchost.exe kicks in and uses all the cpu's so I can hardly get any programs to run. I have resorted to opening up the Task Manager and stopping the svchost.exe that is the culprit. Then everything runs fine. I know that the svchost.exe is most likely a Microsoft program (Windows Update and Windows Defender) that you need to run.

I'm not a complete n00b and i got rid of isass.exe which was causing my system to shut down in 60 seconds. However I haven't been able to stop another problem I have which is the Generic Host Process for Win32 Services problem that usually comes with blaster. I doubt that it's blaster though. also could anyone suggest a good security combo I could use. Anti Virus Firewall and Anti Spyware I've become quite used to NOD32 and I don't like using the other memory hogs... I need suggestions for anti spyware and firewall that would go with NOD32.. or just any good solution that would prevent this from happening again and that wouldnt consume all my memory up.

There is a process called svchost.exe using up almost 100% of my resources and making the computer almost useless. What is causing this or how do I find out what is causing this problem? I am running Windows 2000 Pro.

Whenever my laptop boot up to Windows XP, just when I thought everything was loaded properly, the svchost.exe would start to show 100% CPU usage. I checked through the previous posts and realised that most of the pp seemed to have the problem only when they are running Microsoft update or when they are using AMD CPUs. However, I am in neither of the 2 categories. Also, I think it was mentioned before that I could possibly check which program that is using the svchost.exe. But when my laptop is having 100% CPU usage, basically it does not respond to any instructions, may I know how can I check the program in that case? Is there something similar to a log file that I can look through?

a Dell Latitude laptop with XP pro, SP3 and all updates. Recently I found the cpu running at 3-4 % with only the desktop, Avira, and Windows Defender running. Normally cpu is down to 1% with these programs running. I turned off automatic updates and avira and defender but cpu was still at 3-4 %. How can I find out the cause of this? I do not know which of several svchost processes is causing the problem, this one uses about 35Mb with firefox open, 31Mb when I close it.

I deleted a file called svchost.exe because Norton said it was infected with a virus. I use WinXP sp2. Now I can't find my taskbar at the bottom and I can't go online.I made a full system back up a few days ago.If I can restore this file(s), I think there were three of them, I think I get my computer to work properly again.The problem is where are these files located? If someone could look on their computer and tell me I would appreciate it.There variations on svchost.I know one was svchost.exe. I also know one was located in Documents and Settings.

I posted a forum topic about this months ago. I thought the problem was fixed but it came back. My computer going screwy again. I scan my computer for viruses everyday. When the error popped up, I did system restores about 6 times, but still won't fix the problem. I think I have a virus that my virus scan didn't pick up. I am running out of options my last plan is a full restore back to factory default. But SVChost.exe is stopping my backup efforts.
