I'm call in Symantec support, leave information about the problem, do not call back back.
ok., i'm in SEPM Liveupdate definitions policy change last IPS manualy on 02/25/2015 r12 and IE8 in Windows XP not crash on all PC.
If change IPS back on 02/26/2015 r13 or 02/28/2015 r11, IE8 on WinXP crashed :(
Leave 02/25/2015 r12, while Symantec does not correct the error.
