Svchost Problem

[Sir Doge]

Hello everyone! Right now, every time I start up my desktop computer, the process Svchost instantly uses up 100% of my CPU. It started yesterday, and I haven't installed or downloaded any new software/programs. I've checked with Windows Defender and Malwarebytes Anti-Malware and have no malicious or any other kind of bad malware on my computer. I've checked the Internet but found no useful information regarding this, only a handful of "solutions" that don't really work.

I've got Windows 8.1 Professional and something like this has never happened. What can I do?

 

Any help is appreciated.

Thanks,

Sir Doge

 

P.S. Attached is a screenshot of my Task Manager.

Check MSConfig, can see if it's in the startup. If it's not, just kill the program every time your PC launches i guess. I'd recommend doing a full virus scan with AVG or somethin.

That's indeed not right, it's probably a virus that's trying to hide. I would try to figure out where it's located and just delete the file.

SVChost.exe is itself, not a program, it runs services for other programs, go to MSConfig, and disable everything you can live without, then restart the PC, see if it's 100% again, if not, go through and slowly enable things.

I doubt it's a virus, this would be too obvious for it.

Hi,

 

Please do the following. 

Go to Start | Settings | Control Panel and double click Automatic Updates. 

Checkmark the bottom option to disable automatic updates.

Click Apply/OK and then reboot. 

Does svchost still consume 100% CPU cycles? 

If it does, do the following. 

Go to Start, Run, copy/paste this command and click OK: services.msc

In the list of Services, can you see Background Intelligent Transfer Service ?

If it's not listed, please proceed as follows to register the BITS service.

Open the Windows Search tool, copy/paste the following and then click Search: qmgr.dll

Search should show that file in the following locations:

C:\WINDOWS\system32
C:\WINDOWS\ServicePackFiles\i386
C:\WINDOWS\system32\bits

It may only be present in C:\WINDOWS\system32, but provided you can see it, do the following to register the service.

Go to Start, Run and copy/paste: regsvr32 qmgr.dll and click OK

Do the same with this file: regsvr32 qmgrprxy.dll

Reboot the system and then copy/paste this command into the Run field:
%windir%\System32\rundll32.exe setupapi,InstallHinfSection DefaultInstall 132 %windir%\inf\qmgr.inf

If you're prompted to insert the Windows installation CD, ignore that and in the dialog box at the bottom, change the path to C:\WINDOWS\ServicePackFiles\i386

If you could only see qmgr.dll in C:\WINDOWS\system32  change the path to that instead. 

Restart the PC again and then go to Services and you should be able to see BITS in the list.
Double click it and then on the General tab, click the Start button to try and start the service manually. This is just a test to ensure that it's working correctly.

If you get Error 2: cannot find the file specified, go to Start, then Run again and copy/paste the following command and then click OK:
Reg add HKLM\SYSTEM\CurrentControlSet\Services\BITS\Parameters /v ServiceDll /t REG_EXPAND_SZ /d %windir%\System32\qmgr.dll

Reboot again and then try once more to start BITS. It should work properly now, but in the unlikely event that it fails again, run the following command and then hit Enter:
Reg add HKLM\SYSTEM\CurrentControlSet\Control\BackupRestore\FilesNotToBackup

Reboot once more and then do the following.

Go to this link and install the  IE8 cumulative December update:

If you use IE7, use this link instead:
http://www.microsoft.com/en-gb/download/details.aspx?id=41442

Finally, go to the Windows Update site and you should be able to download normally.

 

Hope this helps... !!!
