This seems to have "infected" multiple locations in /Library. First, quit Safari. Might not hurt to also run the following command from a Terminal (it will prompt you for your password):
sudo launchctl unload /Library/LaunchAgents/com.conduit.loader.agent.plist
Then, delete the following files/folders by moving them to Trash and emptying it.
Note that / is your Macintosh HD, and the Library folder might be invisible. To access it, press ⌘⇧G in a Finder window and enter
/Users/<User name>/Library/Application Support/Conduit
That should be it, according to forum posts and this cnet.com article.
