The Ring Horcrux didn't injure DD, but the terrible Curse that was 
upon it. (HBP -Chap 23) DD was able to destroy the Horcrux in the ring 
and keep it wearable, even if cracked.

DD said a lot about the Horcruxes in that chapter.

DD recognised the Diary as a Horcrux from Harry's explaination and 
started his quest for other Horcruxes.
 
DD was the one to suggest the snake as the Horcrux although he 
said, "it is inadvisable to ...confide a part of your soul to 
something that can think and move for itself ...", so I doubt Harry is 
a Horcrux. Nonetheless, the soul can be removed or destroyed without 
damaging the vessel if no Curse is upon it (IMO).

The Horcruxes should be protected. 

- The ring was in the Gaunt shack with "many powerful enchantments" 
with "magical concealment". (HBP Chap 23) The locket had enchantments 
and concealment too.
- The snake stayed close to LV himself
- The diary was in Malfoy's safekeeping until orders came from LV 
himself (but Auther was looking around Malfoy's house too much, so he 
sought to open the Chamber of Secrets and get rid of incriminating 
evidence at the same time.

DD in his 150 years may have delt with Horcruxes before, which is why 
Slughorn said DD was "particularly fierce" about Horcruxes. Was 
Grindelwald destroyed by getting to his Horcrux in 1945? (DD's Choc 
Frog card)
