Unable to enter websites ("One More Step" captcha window)

Hello, i need the help. It never happened to me, but since yesterday i am facing strange Cloudflare “One More Step” window with captcha verification before to get on desired website! The screenshot of this windows below. It is ULTRA annoying! It completely changed the behaviour of my internet… (you can just imagine!). I am really angry about this. I really do not know what is happening and what to do…

So i have created the account in faith that somebody (i.e. Cloudflare) will help me, and make my internet usable again!

Can you help me, please?!
Thank you in advance!
