Dear Peter Kerry:

In spite of my saying this is US English, it is widely accepted wherever people speak English anyway and it is an I.T. term; bots (which stems from robots) are tiny pieces of (very well written) software that scan, monitor, read, canvass, probe, and, in the case of computer hacking, also work for 'the dark side', spying and tapping on the bits of data and sending them to their 'masters'; the correct expression would be robot or, to use the most modern alternative, 'bot'. Banks use it all the time and large corporate sites in the Web use bots; some of them even place them in people's computers without the proper authorization; they should not be confused with cookies, tiny strings of info that are static; bots are almost sentient (it depends n how deep the code goes in the programming); check the link below and se for yourself; or type it into a search mechanism. Cheers.

Hope the word 'bot' will solve it for you; Cheerio!
