Whenever I connect to my broadband internet, it shows this message - "HTTP Status 404 - /ssssnpm//promotional.jsp" Apache Tomcat/7.0.57
I searched a lot about this issue but couldn't find it. Everyone is talking about Tomcat or Apache servers. I don't use any IDE. I am not a programmer, so I didn't write any codes. I am just not able to open any web page. Whenever I enter any URL, it redirects me to another URL, which seems to be an IP address. And, that page shows this error message (wrote above).
I suspect that it could be because of an antivirus I installed a couple of days ago on my laptop and my phone as well. But, it's showing the same error to my brother's phone on which this antivirus isn't installed.
other internet connections are working fine on my laptop - like my mobile internet.
Please help in resolving this issue.
