PPRuNe Forums - Using hosts to stop pop UNDER adverts

When sites that I regularly use employ pop-under adverts that don't get stopped by pop-up blockers, I simple edit the HOSTS file to block them with 127.0.0.1 instead. In fact, I use a HOSTS file I found on the web that has pretty well all the common advertising sites built in to it so it's very rare that I get a pop up or pop under that "beats" my measures, and therefore just as rare that I need to edit the file to add a new one.

The ITV-F1 website is however now employing advertising from utarget that I haven't been able to stop with IE7's or Firefox's blockers, or with the HOSTS technique.

IE and Firefox are the *ONLY* two browsers that are allowed to be installed on my work laptop (so please don't recommend Opera or A N Other browser).

Also because it is a work laptop, I must leave Javascript enabled.

I am though most interested in learning why this (flash player) pop-under ad can beat my precautions and within the two constraints above, how I can block it.

For the record the entry I added to my hosts file says "127.0.0.1 utarget.httpsvc.vitalstreamcdn.com" without the quotes. The parent site of www.utarget.co.uk is already blocked.

Cheers!
