hi, it's a bit late already solucion layers but maybe this will help someone else to me it worked: You have to go to Control Panel> Programs and Features, and check for any that "Yontoo" is called. If I uninstall it because it is an Adware, software not authorized by you opening advertising without your consent.
if they work or not, please publish your response and thus help others.
I had the same problem these tabs (with mozilla firefox) that opened alone with advertising and solved it well.
Another thing I read was to disable extensions, but my thing was that program.
luck
