You sure you are not using any proxy? Press WIN key and type proxy, then check the settings "Change proxy settings".
Set "Automatic proxy settings" it to
"Automatically detect settings" Off
"Use setup script" Off
Set "Manual proxy settings" to
"Use a proxy server" Off
Disable your network adapter within windows and reenable it afterwards.
Or use the cmd prompt (with admin mode) and type:
Afterwards
Let your virus and anti malware tools scan if you got malware which activates the proxy somehow.
If still something blocks it you need to add the Minion.exe file to your antivirus whitelist/exclusion list!
And start Minion as administrator!
