Problems with csrss.exe

I have been having problems with csrss.exe hogging system resources. I know csrss.exe is a critical system process, but it looks like I have two of these processes running, the second (and suspicious) one being C:\windows\system32\dll\csrss.exe. The processes explorer.exe also hogs resources occasionally, but there is not a duplicate process here and it's only once in a while, so I don't think the two problems are related. I ran Ad-aware 6 to check it out but the file was not detected. Symantec AntiVirus also doesn't detect anything wrong with it. I've removed csrss.exe from the startup list and that works great for a while, but eventually it gets started up again. Below is my hijackthis log. Can anybody help me out here?

Hi gpaciga,

you are correct, the one you refer to is up to no good

Have only Hijackthis running and fix :

F0 - syst>m.ini: Shell=
F0 - R >ystem.ini: Shel>=
F0 - R >ystem.ini: UserInit=

O2 - BHO: NavErrRedir Class - {00D6A7E7-4A97-456f-848A-3B75BF7554D7} - C:\PROGRA~1\PERFEC~1\BHO\PERFEC~1.DLL (file missing)
O2 - BHO: (no name) - {CD209A08-98B5-4669-AF9F-447AC5253356} - C:\WINDOWS\System32\CSapp.dll

O4 - HKLM\..\Run: [csrss] C:\WINDOWS\System32\dll\csrss.exe

Restart PC after doing so and remove :

C:\WINDOWS\System32\dll\ <- this folder

Hope this helps

Cheers,

 

I did just what you suggested and there's no sign of the csrss.exe process anymore. My computer's running a lot better overall after doing the whole cleanup too. Thanks!

 

Hi gpaciga,

take care

Cheers,
