It seem that Google has experiencing a little technical problem just a few minutes ago. All my search results were brought to a page saying that visiting the web site may harm my computer. At first I thought it was only me.
Just a minute later, I saw some other people on plurk and twitter are getting the same warning message when they tried to open the page from Google’s search result. It said “Warning – visiting this web site may harm your computer”.
I think they already handle the problem. My search results are no longer redirected into warning page as a few minutes ago.
This ‘unusual event’ also reported on Neatorama.
