If you go to a site that is Blacklisted by Google, you will see a new (and prettier) malware warning now if you are using a Mac:
The Website Ahead Contains Malware!
Google Chrome Has Blocked access to site.com for now.
Even if you have visited this site safely in the past, visiting it now may infect your Mac with malware.
Nothing major has changed, but we found this new wording to be more clear for the end user. So good move from the Google/Chrome team.
If you have additional concerns regarding getting your site removed from a blacklist the one above, let us know and we will be happy to help.
