For the past few months, JoomlaHacks.com has been branded by Google to be potentially harmful. It was marked to be distributing malware which of course not true. And I found the culprit!
Apparently, the jQuery library I was using is being identified by Google as a malicious script. It's so ridiculous. I got the jQuery library directly from jQuery bundle development download. So what's the fix? Use the jQuery library which is hosted by Google.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" type="text/javascript">
</script>
