schwicon looks alittle funny but the rest are all good exe's. The QW exe's are your quicken launch exe's and your ZClient from the most I could gather is a pen based or laptop application or an MSN game application so that is also okay. Unless it is the Nimda Virus.

The others are for your graphics card drivers traybar and the others are actually all good functioning background processes that are either necessary to keep certain things functioning (systray for example)

If it takes a long time for your pc to shut down or long time to start then you may be infected. It means that there are executables still trying to run in spite of the shut-down command.

Do you use Ad-aware SE? that and spybot may give you an idea as to what you have.

My last tower was a *8se OS but was ripped up by scumware. Be careful.
