Why does Google require captcha?

Question

Google

I sit exclusively on Linux. Google keeps asking for a captcha.
Could someone have remotely accessed my Linux machine, or could there be a script running on it, and how can I check this? + There are five more Windows machines on the local network, can this problem be caused by them?

Answer 1

Maybe. If there are many requests to google from one ip. it will ask you to enter a captcha.

Answer 2

Why...: Suspicious requests
may come from your ip Can...: yes they can
How to check...: carefully check the list of running processes
More machines on the network...: yes
This often occurs with providers with gray ip

Answer 3

Well, any virus from windows can break into Google, and it fires.

Answer 4

most likely, you are sitting behind a provider's NAT,
besides you, there are several dozens (or even hundreds) of people behind one IP
, look in the IP router on the WAN and compare with what 2ip.ru shows

Answer 5

such a topic also periodically arises (Ubuntu 14 LTS). was even on the first day of installation of the system. so viruses are practically excluded. but still not always.

Answer 6

TURN OFF RDS BAR AND THAT.
