I am getting a CloudFlare – attention required / congdonginan.com check prompt on most of the sites I visit through my Macbook running OS X Yosemite, these sites work perfectly on other devices (such as iPad, iPhone, Android and Windows based laptop) connected via the same network/WiFi.

I have tried many anti-viruses and malware scanners but nothing found so far.
In any case, it would be a good idea to do a packet capture and see what's your computer is really doing behind the scenes. –user42178 Dec 28 “14 at 12:50
Cloudflare has stored cookies from your macbook, you may have used proxy or violated something earlier and cloudflare stored your cookies, and the cookie is same every time you visit. So everytime you visit webs behind cloudflare it says attention. Try deleting browser and system cookies and try that website again.
Check if you”re using a proxy such as TOR, these IP addresses often get used to DDOS websites or perform other malicious activities, hence the block.
