net start

or by right- clicking Computer , select Manage , expand " Services and Applications" and then click Services. The first method has the advantage that only those who are running. There are many things that are common to many services : how they start , how they interact with the system and how they are run. Instead of writing a complete service from the beginning , many implemented as a type of program that is run by a different program.

The host application is just svchost.exe , which is designed to host one or more actual services. It is the program that is running and instructed then what service it will include . The actual service is normally found in a dll file svchost.exe to connect to and program may actually host multiple services at once. So even if you have some of Svchost in the process list , it probably means that it's about even more services .

In this program , you can hold the mouse over the different instances of svchost.exe to see what services it runs .

Since it would normally be expected that there will be multiple copies of svchost.exe and its function is quite mysterious for the average computer user , there have been manufacturers of malicious programs have taken advantage of this either by trying to run their code as a service or through to give it a similar name .

File protection in later versions of Windows has made this very difficult and it's probably long ago it occurred , but it is then from there the virus data comes . Since you're running Windows 7 - and probably a reputable security software, in addition, - you need not be worried in that regard.
