Computer Help

[Troy F]

Hopefully one of you guys with some computer knowledge can help me out here.

I seem to have a bunch of things running on my computer that I don't know what they are. When I press control alt delete I get a whole swack of things.

Are all these things neccessary? If not, what are they? I do have kids but they've been banned from the computer since a certain police incident.
