92 | Why do I have to complete a CAPTCHA?
88 | 89 |Completing the CAPTCHA proves you are a human and gives you temporary access to the web property.

99 | What can I do to prevent this in the future?
94 | 95 |If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware.
96 | 97 |If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices.
