Plugin seems to be cracked

As soon as I installed the plugin my Sucuri Security Scan alerts me:

http://labs.sucuri.net/db/malware/malware-entry-mwjsgen2?web.js.malware.fancybox.001

I have been also contacted from a few people telling me that my website was redirecting them to other SPAM pages.

Please make sure before installing that this issue has been cleared.

Cheers.
