Cannot log into the WiFi due to blocked website called hla2.safemovedm.com

I just got a new LG G3 running android 5.0. On my schools WiFi, there are blocked websites. When I try to connect to the school WiFi, it comes up with a terms and conditions screen (like the ones you see at Starbucks or other free WiFis), but it says that I am trying to access a blocked website called hla2.safemovedm.com. I can bypass this by getting one of the teachers to log me into their administrative accounts, but I don't want to have to do this every time. Is there a fix for this?
