Spyder: Can't launch nothing from Anaconda

[rb1990]

Problem Description

I am new with anaconda spyder and python, but I just downloaded anaconda and trying to launch spyder. The window with spyder 3 it does open (check the image) but nothing come up. after few minutes everything disappear and I get this error (check image 2).
Can please someone help me? Thanks a lot.
I've got the same error with qtconsole.

What steps reproduce the problem?

1. download anaconda 5.2 python 3.6 spyder 3.2.8 on windows 10 64bit
2. open anaconda launcher
3. launch spyder

What is the expected output? What do you see instead?

I expected spyder to open, but I don't see anything happening. It seems spyder is running, but it doesn't show on screen.

Did you try my last comment yesterday? Please open the Anaconda prompt and run there

conda install -f zeromq pyzmq

@mingwandroid: any ideas about this one? Google doesn't seem to help...

[mingwandroid]

Probably a virus scanner getting in the way?

[ccordoba12]

Good advice @mingwandroid, thanks!

@rb1990, I hope deactivating your antivirus/firewall works for you because I'm really out of ideas.

[rb1990]

Can't believe, I finally get it. Was definitely a virus scanner in the way. thanks @mingwandroid and @ccordoba12 for helping me. Really thanks!!

[ccordoba12]

Good to know! Could you describe what you did to fix this?

[ccordoba12]

By the way, I'm closing this because it's solved.

[rb1990]

Sorry for the late reply. Anyway, was an antivirus getting in the way. I just uninstalled "malwarebytes" and then install again Anaconda. Everything was fine. Thanks again
