Security, Malicious domain blocking

What is malicious domain blocking? Why am I getting an error saying the page has been blocked by the University of Illinois Office of Privacy and Information Assurance?

Starting in 2014, Privacy & Security began a more aggressive but transparent blocking of malicious domains known to either infect visiting computers, host phishing scams, or otherwise enable and further malicious network activity.
