The problem started after I removed AV Security Suite (a virus). It didn't scan and I removed it right away so I am not infected from that but maybe because that's when it started. Some of my applications like Curse Add-on Client and World of Warcraft will not connect to the internet since then. I have scanned my computer with a bunch of things. I have genuine Mcafee and I scanned with this and Malwarebytes, and I have found nothing.
