Hosting company's get 1000's of exploits all the time, I don't mean to say they won't do anything, but chances are it's a no win situation. They have 1000's of pages of logs and to really go through it all for the little guy paying them $5 per month even $30 to $40 per month there really isn't much they will do. They will just tell you to secure and harden your site.

What it comes down to is no site is 100% hack proof. You need to read up and follow security measures. Just the way it is.

Even see more microsoft is far from hacker proof. So don't expect your host to secure your site. But they may help you restore files if they are decent.

Most of this can be prevented with following security threads, choosing a decent host from the beginning and keeping your dolphin up to date.
