Connecting Glitch? Any Fix?

So i started up my pc today and realized that real time protection turned on and it deleted some of the files. So i started it up and i went into Multiplayer, when it was done loading stats, it started saying "connecting". I left it loading for 1 hour because i had to go do something and when i back it was still connecting. So i deleted all of my files (including bo1) and i redownloaded it. I went through the same process and it got stuck on connecting again. Any Fix?
