Most filter everything other than viruses. From what I've been told, viruses are more of a concern South of the border, in jungle areas. The owner manual that comes with your filter should tell you what it covers.
Any filter system will have a lower limit on the size of particles that it can filter, so the added step of boiling will always be advisable to make sure that you get viruses, smaller bacteria and cysts/spores that your filter may not handle. A VERY small quantity of bleach (like 1 small drop per gallon) or exposure to UV light can also help control some of those water-borne hazards, but boiling is still advisable.
You also have to weigh your immediate need for water - if you will die of thirst before you can get the chance to boil water, go with what your filter will give you and take your chances.
As long as you don't venture to third world countries, a quality filter will take care of any biological nasties in the water. They will not, however, take care of industrial pollutants, nor most viruses. The good news is that these things rarely occur in the places where sportsmen spend their time. Here is a FAQ that might help: http://cascadedesigns.com/MSR/FAQ/Water-Treatment-and-Hydration
To play it safe when you don't have the opportunity to boil, carry a bottle of iodine tablets which purify the water. It adds a different taste to it(which I wouldn't classify as good or bad) but the water is safe.

Different filters filter different things. You should read the package it comes in to see what the filter takes out.

I would say boil the water..like they say "better safe than sorry"...but I would also reccomend to read the package to see what the filter covers.
you should boil the water thats get all the bacteria out of your water.
boil anyway just to make sure, better safe then having diarreai.
You can trust the bottle when you need to but when I have the opportunity I boil the water just in case.
I'd boil it regarless of what the filter said it could do.
