Why do I have to finish a CAPTCHA?
Completing the CAPTCHA proves you are a human and offers you momentary access to the web home.
What can I do to avoid this in the future?
If you are on an individual connection, like at home, you can run an anti-virus scan on your device to ensure it is not infected with malware.
If you are at an office or shared network, you can ask the network administrator to run a scan across the network searching for misconfigured or infected devices.
Another way to prevent getting this page in the future is to use Personal privacy Pass. Have a look at the browser extension in the Chrome Web Store.
