shut down is very slow (V3.0.12.266 X32)[BUGREPORT]

shut down is slow - it seems that it won’t shut down, i can click over and over shut down.
Eventually it does shut down.

XP Home, OEM, Toshiba M70-320
Antivir PE
Script Defender (forgot i had it)
DefenseWall (this was not installed prior, problems were there before; no apparent conflict between the two)

Still have to try it with D+ disabled.
