Do I need to update my database prefix in Ataualpha options?

I changed my site's database prefix (usually wp_ I think) to something else for better security. Do I need to update this prefix in Atahualpa somewhere?

(I'm asking because I got hit by the pharma hack, finally think I got rid of it, and now I can see my posts in the dashboard, but I get a 404 error when navigating to them from my homepage. The index page appears fine.)

TIA!
