Does you friend have a LifeCam Camera a (Vx3000) perhaps from Microsoft? Thats what that process is,
However I don't know why it is taking so much resources?
If you don't use the the software I would think you can unstall it. Make sure you have a the driver
for it.. as it should still work without the software.. (I have not used LifeCam before but I would think it would still work without the software as long as you have the driver for it)
Hope this Helps..
