Can't open facebook

I can I check NIS isn't blocking facebook on my PC?

I can connect to facebook with my account on another device at home so I know it's not...

1. Facebook

2. My facebook account (I also have no probems from my mobile)

3. My ISP

4. Chrome (As it doesn't work from IE or an incognito window)

The only thing I can think of that's unique to this PC is the AV suite.  Anyone else had similar problems?
