It involves finding infected files and removing them, and it involves checking the wordpress database

This is shit I really don't know how to do - meaning, how do I know if a file is infected?

And furthermore, I DON'T HAVE ANY TIME!

I've got THINGS to do.

Important things.

Like...

Conversing with myself on Plurk.

If I were you I would take the tables, wipe the old filesystem and use the tables in an entirely new install.

Changing all password etc of course but I assume you have already done that.
