There is this website that i go to - when i click on any links or images, it will open an ad website in a new tab. This only happens to one particular website that i go to, and it happens to all the different browsers that i used - Safari, Chrome, IE.

I understand that maybe i have malware, but why does this only happen to one website?
The other pple in my office is getting this problem too, but in any place, on another network, this problem does not exist.

Is this a website or computer issue?
