Freeze on Watch Dog Initialization Screen

Thank you for getting back to me. I tried that, but it is just doing the same thing. I can't even boot the laptop in safe mode as this screen comes before the Windows screen.

I restarted my Lenovo Z500 laptop earlier but after the Lenovo screen came up, a black screen came up saying "Watch Dog Initialization" and proceeded to go through a list of things it was doing. Usually after it says it's finished, the laptop continues to boot up and I can use it. However, now it's saying Phase 1: finished, and staying that way. 

I found a potential solution on the Windows forum requiring me to download a Windows 10 ISO and boot the laptop off of the disc with it on. But also many have said this is an anti-virus issue, so I wanted to see if there's an easier way to fix this issue before going through with the ISO. 

Thanks,
Daniel
