Give it plenty of time to ferment out (5-10 days). Anything that's not an infection will fall with the krausen. Anything that is an infection will still be colonizing on the top of the beer.

It is REALLY hard to infect a beer with bacteria. You have to pretty much hand deliver bacteria into the beer straight from your own hand to infect a beer. Even then, most bacteria can't survive in the alcohol and CO2 environment. So 9 times out of 10, it is just a weird krausen. Give it some time and it'll probably fall out of the solution.

How do you tell when it's infected? I think Fat Bastard said it best;"when it smells like hot sick,a$$,& a dead carcass!".

If it's still fermenting, pay no attention to the smell.
Of all tyrannies, a tyranny sincerely exercised for the good of its victims may be the most oppressive. It would be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience. - C. S. Lewis, English essayist & juvenile novelist (1898 - 1963)
