Spyder: Spyder crashes because of socket initialization errors on Windows

[Niveleee]

I downloaded Anaconda last week and have never been able to load Spyder. The same error message keeps coming up that spyder crashed during last session and to try resetting spyder by "running spyder with the command line option '--reset': python spider --reset." I tried and that doesn't work. Other solutions that I found were to delete the spyder.lock folder and I do but that also doesn't resolve anything and the folder reappears after I try to load Spyder again and nothing happens. I've tried deleting the entire .spyder-py3 folder as that worked for some people but the folder also reappears.

What steps will reproduce the problem?

1. Open up anaconda navigator
2. Doubleclick on spyder 3.1.2
3. Error message appears that spyder crashed during last session

It seems your antivirus/firewall is blocking Spyder's attempt to open a socket in your system.

What antivirus/firewall are you using?

[Niveleee]

I'm using Norton 360 Premier.

I disabled Norton and tried loading Spyder again and it still doesn't work. I will try uninstalling and reinstalling with Norton disabled and see if it will work then.
