Minecraft problem: when starting comes (no response)?

As mentioned above, I have problems starting Minecraft…

I've already tried all the restarts and updates… In vain!

Vlt. Do you have an idea?

-My virus protection is Avira, in case that is important in any way

Uninstall and reinstall

That usually helps over and over again, just restart the router

Yes but how can it be because of the router… Other things work the same way
