Svchost.exe 100 cpu after virus

I could run the windows system restore and just go back to two days ago, but I don't know that I trust it entirely because of other recent experiences with "helpful" automated microsoft utilities. I just spent an hour with Microsoft Technical Support - what resolved my problem through trial and error of unchecking services in msconfig - was to go into msconfig, services, and see if HID Input Services is checked. Stands for Human Interface Display.

Uncheck it and reboot. It worked for me after days of trying to figure out what was going on with svchost. You can go into the Registry and see all the things running under SvcHost. The way I found and fixed this problem was by downloading Process Explorer from SysInternals, which is now owned by Microsoft. It showed me that WuAuClt.

I downloaded this hot fix and it made no difference on my system.

OMG, I have spent endless amounts of time trying to fix this problem and thought I would have to reformat my hard drive. Thank you! So i try to uninstall the controllers of the NIC, enter safe mode and try to navigate and nothing happens, the error still was there. I even repair and then format my windows partition with my cd of windows but neither of them work. Do you know what happend and how can i repair it??

Thanks for answering. Hi, Just tried everything to fix this same problem — eventually discovered it was my Tom Tom Sat Nav programme which was running in the background that was causing the problem!

Tried registry cleaning, but no significant difference. Then I came across the above comments re HP. I was using an HP Deskjet F for its scanning feature. Hmm, I wonder?? Uninstalled it and the problem has disappeared completely. Looks like HP might have a basic problem in their software philosophy. Thanks for this forum.

Tom C. I simply renamed hpslpsvc In vista ratings my computer represent as 3. I always format the windows drive and reinstall the windows.

It works for a few days! Have a nice Time! I had some issue earlier while i was writing DVD in the middle of it said my windows was corrupted. Then i formatted it then it was ok. I tried seeing if it was only giving me issues when I was online, but it was still going. Hi there. I had the svchost. Please help. So thanks to Kevin Scoot and Leo.

Thanks for the tips. Found it was caused by two print jobs lurking. Very simple. Now everything works like a charm! I was suspecting that the antivirus is problem, after uninstallinf every thing comes to normal. Try unplugging any extra mice or keyboards, or install the correct driver. You can disable HID from services. Everything started after I tried to go to a website for examples of business letters. What now? I have been running every antivirus I can. Even paid for some….

My issue was a bit different, but the help you provided here guided me in the right direction, and gave me enough help to fix it. I thought it had been acting a little weird lately, with these borders around the edges that do not normally appear.

But I had no idea that it was causing the CPU problem. Afer I closed Windows sidebar, it fixed it. My fan has been running constantly for weeks. Thank you VERY much for your help!! My ears feel much better now!! I was afraid that once I re-opened Windows sidebar, that the same problem might start happening again, but so far so good. I know I should probably still clean my computer, so I will have to work on that too.

Thanks again!! You rock!! Just another note. I also found this link helpful. Apparently other people have been having the same problem with the windows sidebar hogging CPU. Can you please help me in what should I do to fix this problem?

In my case, it turned out to be a piece of software apparently running under svhost. This programma needs to be updated with the februari version. This was what solved the problem for me. Hi Leo, I was having a problem but really did not noticed untill it got serious. Holy crap, this really helped!

Wow, seriously, I am so happy for this information. None of this worked for me…. It found quite a lot the first time through and I ran it a second time for good measure. Everything is back to normal this morning…maybe this will help if none of the other recommendations are working for some poor soul out there! You know, I set up my OS many times.

Now I know the solution. Thank you again very much. Love Yarith Siem Reap, Cambodia. Problem is over. Thanks Ron. I found svchost. I had this svchost. There was an email worm which kept trying to send emails and Symantec email proxy kept blocking it.. When I right clicked on the one of the svchost. May be the reason was that Facebook was refreshing often…. I had recently installed a plug-in for Firefox and thought that might be a problem..

After disabling that plugin, it has been good so far…. Also, has a lot of other relevant links inside the article, which helps to go into more specific troubleshooting:.

I have found that this is effecting not only Windows XP systems but also Windows Server R2, no cases recorded of Windows 7 systems being effected.

Could someone advise? Thanks Justin. Microsoft made the fix. Killing svchost after every reboot fixed the problem, but with side effects like not being able to open Microsoft website, and losing network connection after a Hibernate.

I found another solution later. My CPU does not go to idle? How can I find the process that is causing this problem? I am a vista user for 3 years now. I always update my windows for the latest update and there is no problems happen before… Until one day… suddenly my laptop is kind of slow… even watching video the video seems hang-up several times.

I try to find the reason for this and when I open the Window Task Manager , I see the oddest thing ever… my processor is working so damn hard. Doing some research to find the reason for CPU high usage, it takes me several hour I am a noob to find the resource. I flash back my previous usage of the laptop and remember that I used the windows optional update to update some driver.

It goes back to normal…. So for people that have this problem, you might try to down grade your audio to a latter audio if you have recently upgrade a new version. This is when the svchost problem happens. I have the latest updates, switched automatic update off everywhere and scanned the machine with AVG for viruses and I still have this SVChost problem, It sometimes abates if I switch all internet browsers off and pull out my wireless aerial.

Any ideas or suggestions? Ive been digging around for a solution to the problem for sometime, ive also used this technique to disable my windows defender which causes a lot of CPU usage as well, Great Job!!! Thanks for an insightful and analytical explanation to the svchost issue, Leo. Saved me anxious moments. Keep up the good job, as always.. Is this just a microsoft issue? I have searched the internet and all responses are from to … nothing in … not even sure what to search for ….

So very frustrated! The answers on this page have helped. It seems like, a few years late! Only took me 2 or 3 hours to find! That update definitely seems to have helped. I went to msconfig to reset wuauserv to start on startup. Instead it went up to MB memory and then dropped to MB after a few minutes. Maybe there was a problematic Windows 7 update just awhile back.

Mate, You are a legend. After a long 4 days trying to figure out the svchost problem. Thank you a million times over. Three month ago I disabled automatic updateing. Two days ago I decided to enable automatic update and search for updates. After 4 hours there was 19 items to update. I today connected my to my pc and got this high cpu usage error Not only my pc is affected by it but also my ps4 is not resounding and giving me the disk error.

I have a questione. Can VPN protect my computer from viruses? The VPN accesses the website for you and sends all of the incoming and outgoing traffic to you. Nothing in that process blocks malware.

A VPN does not protect against malware. You can still download malware regardless of what kind of connection you have. Comments violating those rules will be removed.

Rob Reply. Dont know if that helps in your case i corrected many windows installations in this way give it a try if you allready depleted other solutions Reply. Task manager showes that the network itself is not using a lot of CPU Reply.

The fix you offer up here, disabling WU merely shifted the problem around for me. Idle is the task that Windows does when it has nothing to do. Idle does not cause your computer to slow down. Any help please. The trouble is determining which piece of hardware.

Any particular devices acting up? Check those out, or remove them temporarily and see if it clears up. Thank goodness for Forums like these! Microsoft Wireless Entertainment causing the problem for me too :- Reply.

Why would this happen to approx 15 computers out of on the same day? Really strange. May be the reason was that Facebook was refreshing often… I had recently installed a plug-in for Firefox and thought that might be a problem..

Regards Howard. Howard, I have followed all of the instructions up to the point of using Hijack to "fix" or end the listed processes. Next run CWShredder. Next run AdAware, The log I have provided was created after running the above programs. Do you want me to continue with the fix through Hijack This as listed in the stickey note?

Sorry, I didn't see the very first line of the sticky note perhaps I'm color blind. I renamed HijackThis. Attached is the log file. I still have not "fixed" anything with HijackThis as I am relying on the experts here to diagnose the problem and direct me in its use. Thanks for your help, CJ. Run HJT with no other programmes open. Click the scan button. Have HJT fix the following, by placing a tick in the little box next to if there.

Close HJT. This is a huge security risk. Download and install the free AVG antivirus programme and either the free Zonealarm or Kerio firewall programmes. Install whichever firewall you chose, followed by AVG and reboot your system the required number of times. Run the AVG updates. You might want to copy and paste these instructions into a notepad file. Then you can have the file open in safe mode, so you can follow the instructions easier. Turn off system restore.

See how here. This included anything in the virus vault. Reboot into normal mode, turn system restore back on and rehide your protected OS files.
