BSNL Injecting Advertisements In Your Browser
<div id="__BULLETIN__bdiv" style="position: absolute; z-index: 999999999; visibility: visible; top: 350px; right: 20px; display: block; transition: top 0s ease 0s;"><style> img.scalable { max-width : 100%; height: auto; }</style> <img id="__BULLETIN__bdivImage" style="height: 350px;" src="https://117.202.20.131/bg/FreeCalls.jpg" scrolling="no" frameborder="0"> <div style="overflow:hidden; position:absolute; right:0; top:0; z-index:9999999999;"><a id="__BULLETIN__button0" href="#"><img id="__BULLETIN__button0i" name="button0" class="scalable" src="https://117.202.20.131/bg/CloseButton.png" border="0"></a> </div></div>The IP addresses resolve to BSNL owned servers and it's a clear indication that BSNL's just being nasty. The only solution to the problem, as it seems is that you need to block the IP locally using your router or hosts file. But that's a temporary solution because BSNL can quickly change their IP and the ads will start showing up again.
I think it's highly unethical of BSNL to inject ads in the browsers of paying customers. Have you noticed unusual advertisements in the bottom-right corner of your browser?
