Been hacked – Posts missing

Looks like I was hacked! I just upgraded to the latest WP but still encountering problems. When I click on POSTS in Admin – the numeric values show up as having posts – but below it says no posts found.

When I go to my blog, it only shows my post that I sticked to the front. My Categories are also missing in the sidebar.

Does anyone have any suggestions as to where to look to resolve this?

Please help!!!!!!!
