Google says “this site may harm your computer” to all search result

Google display "This site may harm your computer" for all search result ?

Just now (31-Jan-09 , Malaysia time 11.00pm) , i was quite shocked when I search my website and it appear like this :

Then when I search for other website such as Yahoo, it displays like this :

Then I type "google.com" in the search field, interestingly, it appears "This site may harm your computer" too

Then I type other keywords, it seems all search result are displaying "this site may harm your computer" . I messaging my friend in USA and UK, they said the result display the words "This site may harm your computer" too. Seems this bug affect accross Google data centres in whole world.

However, after 20 minutes , the above error is fixed and turn back to normal search result.

Anyone got any idea what happen to Google ?
