Customer called in with the complaint that video didn't work inside Skype.
Long story short
1) Dell Customer service had disabled almost everything in her startup & still not fixed the problem.
2) it was infected with reva.vba entries in the autorun
3) It had an application Called Fast Access or faster access?
Fast Access appears to be an application that uses the webcam to determine your face and sign you into your PC. However, it never seems to let go of the webcam. I killed the .exe & the monitor service started it back up. I stopped the service then all three FAS... executables - suddenly the webcam started working.
