Solve : Background process almost brings computer to a halt? |
|
Answer» Could you please try to run ESET again?Would it be OK for me to stop the process wuauclt.exe when it runs, as this seems to be the process that brings the computer almost to a halt - or would that do more harm than good? A spurious process is still running each day. It appears to be wuauclt.exe.Are you getting a warning about this file? Wuauclt.exe is the AutoUpdate Client of Windows Update and is used to check for available updates (for the various versions of the MS Windows platform) from Microsoft Update. The wuauclt.exe file is included in the Task Manager’s list of active PROCESSES when it is waiting for a response or an action to be performed by the user. When the spurious process runs, it is sometimes accompanied by a warning message produced by (I think) Norton AV, saying "Win32 Services high memory usage".Please download SystemLook from one of the links below and save it to your DESKTOP. Link # 1 Link # 2 Temporarily disable your antivirus and any antispyware real time protection before performing a scan. Click this link to see a list of security programs that should be disabled and how to disable them. Double-click SystemLook.exe to run it. Copy the contents of the following codebox into the main textfield. Code: [Select]:filefind wuauclt.exe Click the Look button to start the scan. Note: The scan may take some time so please just let it do its work and be patient (or do something else unrelated to the computer). When finished, a notepad window will open with the results of the scan. Please post the log. The log can also be found on your desktop entitled SystemLook.txt SystemLook log:- ********************************************************************************* SystemLook 04.09.10 by jpshortstuff Log created at 10:21 on 04/06/2011 by Administrator Administrator - Elevation successful ========== filefind ========== Searching for "wuauclt.exe" C:\WINDOWS\ERDNT\cache\wuauclt.exe--a---- 53472 bytes[11:39 18/02/2011][18:24 06/08/2009] 62BB79160F86CD962F312C68C6239BFD C:\WINDOWS\ServicePackFiles\i386\wuauclt.exe------- 111104 bytes[20:18 18/09/2008][00:12 14/04/2008] ED7262E52C31CF1625B65039102BC16C C:\WINDOWS\system32\wuauclt.exe--a---- 53472 bytes[08:00 04/08/2004][18:24 06/08/2009] 62BB79160F86CD962F312C68C6239BFD C:\WINDOWS\system32\dllcache\wuauclt.exe--a---- 53472 bytes[08:00 04/08/2004][18:24 06/08/2009] 62BB79160F86CD962F312C68C6239BFD -= EOF =- ************************************************************************* In the course of clicking on the Link in your post to find out how to temporarily disable my AV software, I noticed information on that website about how to fix corruptions of SVCHOST; so I bought that software (Paretologic PC Health Advisor) and ran it. It lets you do a scan without paying but I had to pay for the software to run the fix. ANYWAY, as one of the messages I was getting referred to high memory usage by SVCHOST, I thought this might fix the problem. In fact, it does seem to have gone quite a long way to fixing it, as SVCHOST now runs quickly and hardly slows the PC down while it's running. There is still one outstanding problem, which gives a 'Generic host process for Win 32 Services - high memory usage' message, which I think is the wuauclt.exe - but this seems to only occur only once every few days. So I think there were 2 problems, one of which has now been fixed and the other of which only happens every so often, rather than every day. I think we might be able to put up with this, unless you have a simple solution to it. If you think we have gone as far as is sensible with this, I would like to thank you for your efforts in dealing with this. Your involvement is appreciated.Quote In fact, it does seem to have gone quite a long way to fixing it, as SVCHOST now runs quickly and hardly slows the PC down while it's running.

Very little showed up in all the scans we've run on this computer. You could start a new thread in the appropriate software forum, if you wish. We should do some cleanup. To uninstall ComboFix
