Unusual traffic - Google

[mooks]

Every once in a while Google tells me it has detected 'unusual traffic' and it asks me to enter 2 of those captcha things.

This happens when I type into the search bar/box/thingy in my browser (Firefox, portable).

Any ideas what 'unusual traffic' I'm generating? I can promise I'm not searching anything unsavoury - this is my work PC and I would quite like to keep my job

if it's your work pc then chances are you share the same outgoing IP address with the rest of the company which in turn COULD reflect badly on you from Google's viewpoint if anyone else is doing something unsavory.

However 90% of the cases I've seen it's a virus...
