Google search and the virus attack - beeing paranoid?

Not sure how searching for 'subtility' on google returns me an error with a screen where I need to enter a special word before to process...

See if it works for you: http://www.google.com/search?hl=en&q=subtility
For me, I am getting this.

I also love this dilbert, So I guess I'll share it with you, too.
