Has Google become more stupid lately?

Google keeps trying to be helpful with suggestions, alternate spellings and word tense.  You'd think using quotes would give an exact match, but it still returns spelling and grammar variations.  Google used to return just what I was looking for, not suggest things like it was Ask Jeeves.

    We're sorry...

    ... but your query looks similar to automated requests from a computer virus or spyware application. To protect our users, we can't process your request right now.

    We'll restore your access as quickly as possible, so try again soon. In the meantime, if you suspect that your computer or network has been infected, you might want to run a virus checker or spyware remover to make sure that your systems are free of viruses and other spurious software.

    We apologize for the inconvenience, and hope we'll see you again on Google.
