can anyone help me identify this shrub?

[bunnybunyip]

Hi, my garden is slowly going to rack and ruin so I'm trying to identify shrubs to get my pruning regime correct.
I'm struggling with one (it's on the left, next to the ?spiraea, on the photo on my profile). It has leaves about 10cm long with 3 points to them. CAterpillars (or something) loves the leaves and they are constantly being eaten. IT has just flowered with some pompom like white flowers. It is about 2m tall and wide.
Any suggestions? Thanks

I can't see your profile but it sounds like it might be Viburnumm, also know as Snowball Shrub

Viburnum

Hi, thanks, I think that is a very likely candidate. I can't get my profile to show (there is an error message on there so will try again later).
