Can anyone help on this please. Norton is telling me that a file called csrss.exe is infected with Download Trojan. and and that it cannot repair or remove it.. The file is shown as being located in Windows/C/System and Windows/C.System 32. I am unable to find it in either of these locations. I have tried to delete them from the search facility but access is denied. I have a Trojan Remover facility installed but this does not find it. Is there anything else I can do.
