1-get some bear spray.
2-ether a 2 1/2 686 or a 3 60 loaded with some heavy .357,ether 158 or 180 gr will suffice on most blackies
3-don't shoot it unless it's trying to eat you,bears will run off more then anything but they can be mean SOB's if they decide to harm you.

I've been in WV almost twenty years and have seen one bear and he was going the other way,doesn't stop me from always having a gun on me!

BTW I feel fine with a .45 auto loaded with some older-type 230 gr JHP in the woods.
