Again, notice that I've got a 2000 'Bu, so I have to look up the light part numbers for your car.
So - according to ModifiedLife.COM the 2010 'Bu uses H11s for low beam and fog lights, and H9s for high beam. PLEASE verify both before going further!
THAT said ..
Start at
http://www.ddmtuning.com/Products/Apexcone-Raptor-HID-Kit and order the H11 kit in 4000K for the low beams, the H9 kit in 4000K for high beams (note: you can pick whatever color suits you, but any higher in K and it's not quite as good for lighting the road) - I'd actually recommend just doing the high beams for night driving, leaving the lows as halogen, but it's really up to you on that.
If you have the factory fog lights, order the H11 kit in 3000K (yellowish, better for fog usage).
Cost so far: $25/kit for 35W. So up to $75 if you do all three.
Add to that a relay harness (again, there's other sources, but the one from DDM works), such as
http://www.ddmtuning.com/Products/HID-Kit-Wiring-Harness . This is $8 each pair, so another $24 to do all three.
This SHOULD get you there. So far we're at $99 plus shipping for all three.
Past that, you'll need instructions on how to change the bulbs in your lights (such as at
http://www.gminsidenews.com/forums/f53/malibu-2008-how-remove-headlamp-62075/#post1347164 - which is for a 2008, but RockAuto lists the same headlight assembly for both, so I'm presuming it's the same).
Matter of fact, that whole thread was about doing HIDs in a 2008 - which, again, supposedly uses the same headlights as the 2010 your profile says you have. (Like for my 2000 - I can use 1997 - 2005 Classic instructions, they're all the same there.)
For the relay itself - biggest thing is finding +12V and GND near enough to do good. My relay harness is currently connected to the screw into the fuse box, but again, that's on a 2000 - I'd bet something similar is available for the 2010. Ground was to a new screw into the inner fender, by the battery (self-tapping with lock washers both sides to make good contact, drill hole, sand off paint, install ground, spray new paint over it - black engine paint, but it's hidden by the battery so meh for me. Others will screech and do a perfect color match, that's them.)
I hope this helps enough.
Again, I'd SERIOUSLY consider doing just the high beams and fog lights HID, leaving the low beams halogen for several reasions - the better dispersion pattern (halogens have a distinct filament, HIDs not), the lower glare for oncoming drivers, and the reduced glare in high fog situations. But it's your car, do as you see fit (Naturally!)
