I'm really sorry to hear that your website got hacked, but the slideshow plugin is not malicious. It's been checked and hosted by WordPress for over half a year now. If it did anything to hurt your website's safety, then WordPress would have removed it long ago.
It really pains me that you would compromise my hard work by rating my plugin with one star, even though you say you're not sure it was my plugin that caused your website to get hacked.
You say you've seen some damaged files in the plugin, I might be able to help you if you told me which ones they are.
Again, I'm really sorry you got hacked. But I don't see how this is relevant to the slideshow plugin.
