Yeah, i agree. But IMHO he should practise a forensic analisys in order to 
find out what's wrong in that box and how intruders broke into.
If he reinstall everything without realized how that server was hacked...he'll 
be hacked so soon one more time.
Of course if they got shell access or simply ran any kind of binary he's on 
troubles, but he could learn some importans things from that situation and do 
not repeat its on a future, at least, not the same.
So, do not reinstall or delete something until, you know how the hacked. Not 
yet.

Of course, i could be wrong, just an opinion
