What is google up to?

Twice today I’ve had to solve a captcha in order to do a simple google search.
The first time I was looking for “apache confix mac os x”, and it told me that my query
” looks similar to automated requests from a computer virus or spyware application.” I was a bit baffled but I figured that my request MIGHT SOMEHOW be used for malicious reasons, so I blew it off.

But then later I was searching for Victoria Galinksy and got the same error. Now what the hell do spam bots have to do with Miss Vicky? How odd. How annoying.
