Kb951748 old problem is back after Norton update

URGENT childs crying & wandering around like barbarians

something in norton update on 14/aug/16 cause  a "software distribution service 3.0 " to be created in the restauration point. All internet software refuse to start(I.E/firefox/thunder/pale moon). Old problem said the whole internet full of message about that.

KB951748 feel to be responsible. I found it BUT kb951748 can't be uninstall (because now part of a service pack maybe?)

How may I suppressed this KB? Other solution exist?

the conflict & the reason of the new conflict with the norton update of yesterday are not interresting for me.

Old comp for children running XP SP3. Additional info: WinUpdate can connect to internet (Using distinctive port maybe?)

thank's in advance... childs look like angry zombie. (it's holiday here, and the comp is full of game)
