After skype started to throw the following exception when run, it was obvious ads were the cause of the problem. This is just absurd – introduce a program crashing ad functonality – shame on you, Microsoft!
The error message indicates, that ieframe.dll is being used, so it was obvious that Internet Explorer is being called, from within Skype. So, to block skype from displaying anything inside an IE iframe it is necessary to block internet access from IE itself.
If you use IE browser on a daily basis, this method is not suitable for you.
So, to stop IE from working (and displaying Skype ads):
To (temporarily) allow access for IE – untick the “Use a proxy server for your LAN” box.
NB! Google Chrome and newer Opera browsers use the same Internet Connection settings as IE. To make them work, just add –proxy-server command line switch to its chortcut:
Example (works as well on Opera 15+ ):
Enjoy your ad free Skype! (until Microsoft changes the way ads are displayed)
