I was searching this morning when I started to notice warnings that the site I am being directed to might contain malware. I did a news search and sure enough, I am seeing 
results in thailand and on a site called Neowin reporting the same thing. Here is a screenshot of what I am seeing searching site:google.com. Notice how their entire site might harm your computer.
This is definitely embarrassing for Google. People can’t use their product, it will drive people to alternative search engines, at least while it is broken. I imagine it will be fixed sometime today but it the meantime, you can use the old standby’s of www.live.com, www.yahoo.com, or www.altavista.com.
Edit: Fixed now at 10:29am EST
