The good news is I was able to restore 99% of my content thanks to Webhosting Pad's automated backup service. After getting infected with malware many moons ago I thought all hope was lost for a time.
Webhosting Pad came to my rescue by delivering to me a very recent database backup from the time of the attack and by wiping everything out so I could start clean again. Some phpMyAdmin magic and a little TLC later and voila, we're back. It looks like all my old images are now deadlinked, but hey, it could be worse.
