What is "Hacked by Godzilla"?  

Godzilla is some hacker's handle.

He wrote a piece of Spyware or a virus which you got hacked by.

This one was making it's rounds in Asia in December, it's a persistent hack and you probably want to do a full sweep with your Spyware and Antivirus to see if it can clean it off.

If not Google on it and the there are a few links out there that will do the removal for you.

I was infected by this a few weeks ago and goes on not noticing it. It's to believed as a trojan, from Thailand. I've read in on some forums that it is best that you remove it.

Here's a link provided by one of the forumers as a direct removal tool.
Install and run it. It should be ridden of.

I assure you it's a safe site. It's Thailand's Eset Nod32 Anti Virus's website.

some of the viruses etc are written just for IE as that is the most widely used browser. this is also why using other browsers can be safer to use, they have different safety features plus most don't waste time writing viurses etc for the browsers that are used by fewer users. If you are someone who writes these things you want to get as many people as possible and the majority of people use IE, I use firefox but am going to try opera as I have heard that some find it better even than firefox and your experience shows how much safer than IE it is.
