Everytime I open one of many websites, I have to pass the captcha challenge, I have a static IP address for my Sisco 1900 series fiber optics connection, and another static IP address for the ADSL connection. When I use the fiber with any PC I get this screen, with the ADSL in the same PCs I pass normally. So the problem seems to be related to my fiber IP address.
What could be the cause? and how to solve it?
I scanned my PC with different AV software (Avira, Kaspersky, Malwarebytes...) and everything seems clean.
