What is svchost.exe?

Host Process for Windows Tasks is a generic process which acts as a host for processes that run from DLLs rather than EXEs. At startup TASKHOST checks the Services portion of the Registry to construct a list of DLL-based services that it needs to load, and then loads them.

Overview

svchost.exe has been configured with a firewall exception which allows both inbound and outbound network communication without being blocked. The file is digitally signed by Microsoft Corporation. This version is designed to run on Windows 7 and is compiled as a 32 bit program.
