Found this little free program that will explain what all the processes are in task manager.
It puts an icon next to all processes and when you click on one it takes you directly to a web page explaining all the details.
Alternatively you can type the process name in at the bottom and look it up.
For some reason on my pc when kaspersky av is running, i loose the icons but the program still works ok.
I think ill be keeping this one on all my pc's
