A large percentage of my Google searches are coming up with a silly error page...We're sorry (like hell)...but your query looks similar to automated blablabla

1. I don't have viruses or malware on my machine, it's new THIS WEEK.
2. The "type the characters" field has no continue button..you type in the characters then what?

This is stupid. Back to good ole Yahoo searches...I even got the error page with "google" in the search field! Now, that's dumb!
