I have had two WordPress blogs hacked into in the past. That was at a time when I was doing very little internet marketing, and until I found time to address the situation (months later), these sites were penalised in the search engines. They were not removed, but the rankings were reduced.

Don't use wp_ as a prefix for your own databases. That default is being eliminated by web hosting providers but if yours does not, adjust wp_ to anything else but that.
