web pages opening badly

I am using windows 7 ultimate 64 bit. Recently when I'm opening a lot of web pages, they are badly formatted. Some are not even opening correctly. However, my internet speed is very good. I have 1mbps plan which gives me 128kbps download speed. The connectivity is good, but I can't understand why pages are opening badly. This is a screenshot of a page that I opened in google chrome. This happens regardless of the browser that I use. Ive tried chrome, firefox, internet explorer. What is wrong? The websites open fine if I tether my android phone 3G via USB or Wi-fi. I have also faced problem with the website inhabitat.com

This is very strange.. Quite possible that your computer has been hijacked?! (Spyware, a virus, whatever)

I am using kaspersky internet security. Ive tried chrome, firefox, internet explorer. well, had it been a virus then my page wouldn't have opened correctly either when I started using internet by wi-fi tethering of my android phone running on Vodafone

I've used them before. It didn't work out. It's an issue with my service provider because if I connect using WiFi of my neighbors, those pages open flawlessly. . Lately the pages started opening perfectly on my own network.

Unfortunately, issuu.com doesn't work now..
