This technological fantasy, the product of the MIT Students System Project and the inspiration for the 1979 film "Meteor," presents a plan for avoiding a hypothetical collision between Earth and the Apollo asteroid, Icarus, which sweeps by every nineteen years within a few million miles (a near-miss in astronomical terms). Collision with a four billion-ton rock would create a catastrophe equal to the destructive power of half a trillion tons of TNT.
An Ion Beam Shepherd (IBS) is a concept in which the orbit and/or attitude of a spacecarft or a generic orbiting body is modified by having a beam of quasi-neutral plasma impinging against its surface to create a force and/or a torque on the target. Ion and plasma thrusters commonly used to propel spacecraft can be employed to produce a collimated plasma/ion beam and point it towards the body.

With seven days notice, we could not do anything about it other then try and relocate populations.
It takes them longer then that just to put together a rocket and move it to the launch pad, let alone plan a mission, configure a payload, etc...
We could try and slow it with some ICBM's, but they are not really designed for leaving earth orbit, so I am not sure they have enough delta-v to intercept it.
