Guess no one else is around at the crack of dawn.

Anyone familiar with a Droid X? My coworker thinks he has a virus of some sort. Said the other day he unlocked it and the "screensaver" as he put it was some sort of porn advert.

Said he hadn't downloaded any apps lately but he does let his kids use it from time to time.
Well, he tried rebooting it but it hangs at the "Droid" animation. He's completely stock (not sure if on 2.3 or not). I did a few battery pulls and attempted to get into recovery but couldn't. I think part of it is a bad battery or it wasn't charged completely but he said it was on the charger all night. I'm kinda the resident Android freak at work so I'm hoping I can help him out.
Thoughts?
(btw, I'd ask in the DX forum, but seems to be pretty dead there)
