Was My Blog Hacked?

I got a weird notice from my browser that a certain "GOO(dot)IND(dot)IN" is a malware detected on my site. (Pardon me for not acting quickly for a screenshot). Though I was thinking, I was running on a Mac, so I just refreshed my browser and got it. I asked fellow bloggers to check my site and they say that my site was loading from their end. So, I still checked, and the oddest part of them all was that, when I looked at the users, another "ADMINISTRATOR" appeared. Yikes! This is my personal blog - I'm not sharing the admin job to anyone. A certain "OWENG" is an admin of my site. What the? Worst part is, it was registered under my domain.

Now, I'm on a journey, to take this whole morning, to know what went wrong, and where did that "MALWARE" come from, before I get blocked-off the Google search engine.

If you have any advise to add to my (currently) search for answers, please do give to me. ASAP. Thanks.

As for now, I changed my passwords, just to be sure. But I will continue my "quest" to find the culprit, and will blog more about it to help others who may undergo on the things that happened to me, or could prevent this from happening.
