Google Problem? Turn all result to "This site may harm your computer"

Today and a few minutes ago, i'm trying to search some plugin for my Wordpress pages on Google Search but suddenly all search result turn into "This site may harm your computer". As you can see below is an images from the result.


Then, if you click on one of those link it will turn result that says "Warning - Visiting the website may harm your computer!". See the images below.


If we click to all link came from the result it will give a warning of a fake malware. This also include search on images. All the link will return result from the following URL example.

http://www.google.com.my/interstitial?url=http://wordpress.org/

and another error images a few minutes ago...



I guess maybe Google people are trying to test something on the server in real situation...
