The Svchost.exe process is a Windows system process for services that run from dynamic-link libraries (DLLs). The original svchost.exe file is located in C:\Windows\System32, but numerous malwares and trojans use the same file and process name to hide their activities. The free Svchost Process Analyzer lists all svchost instances and checks the services they contain. This makes it easy to uncover Svchost worms like the infamous Conficker worm.
