@tim, yes I have got things back up and running, although it wasn't fun spending a whole day on it! Stupid hackers...
I'm definitely a lot more vigilant now about the plugins I install. It's sad, since a lot of plugins do such useful things...
Thanks for all your hard work on WordFence, ever since getting my sites back up it's the first plugin I installed. I didn't mean to imply in another thread that WordFence doesn't work well or it isn't effective, just that installing it after a site is already heavily compromised might be too late, and of course a site might be compromised through another backdoor besides WP
