smed79 over in the EasyList forums sent me here for assistance. I do not know Kioskea's view regarding ad-blockers, so, if Kioskea is negative toward them, I will confine future posts strictly to this thread's title.
While testing Adblock Plus on Safari, I encountered a site, Newser.com, that displays some ads (mostly MacKeeper banners and AdSupply page-unders) through the adblocker. All adblockers in all browsers I've tested in all OS's I've tested and on all networks and machines I've tested, actually. That includes Firefox, Chrome, and Ubuntu Linux. For more detail please see the thread at: https://forums.lanik.us/viewtopic.php?f=62&t=20215&sid=4e50f8080f08ddccf88660c9cb0123a3
I followed smed79's and fanboy's advice for cleaning my machines, as well as the malware and adware removal guides over at thesafemac.com. I cannot find anything on my machines. Apparently, they do not see the ads that I do, nor similar ones, so, presumably, something is up with my systems, no matter how unlikely that may seem to me. (I've been at this computer thing, digging into them since 1984, so I thought I could figure something like this out. Apparently not.)
Without further input, I don't know what else to say, other than help! I've been dealing with this for more than 10 days now, and I feel I cannot trust my systems until I know what is (or isn't) going on. Can someone else, with known clean machines, at least check the newser.com site for what I describe over at the EasyList forums (above link) and see if the same thing occurs?
Thanks for your input, and for your time with this issue and with EasyList in general.
I understand that you are not seeing the ads on newser.com. However, that does not mean that others don't see them. kefierschild, above, has stated that he sees a floating banner on newser.com in Windows, though I do not know his system setup. I see them in OS X and in Ubuntu Linux.
I have checked my systems extensively, and, as far as is possible to know, I do not have any adware installed on them. I do not install any ad-supported programs, and I only install known, trustable software from known, trustable sources. I do not have MacKeeper installed on my computers, and I've known about that mess of a program for many years and would never install it or any software like it. Besides, why would MacKeeper keep advertising for itself if I already had it installed (no sarcasm intended)? And, to my knowledge, MacKeeper and the various advertising engines out there cannot be installed in linux.
At the moment, the MacBook Air I am typing this on only has installed on it Apple software, Firefox (d/l'd from Mozilla), and f.lux (d/l'd from the developer). The MacBook Pro I've checked Newser.com with, additionally, has Google Chrome (direct from Google) on it. Only well-known, trusted, ad-free extensions have been installed in the browsers, and during testing of this issue, only Adblock Plus is active. The linux install I've tested with is installed on a flash drive and cannot modify itself on the drive. I have to install ABP fresh each time I use it.
The screenshots below are from newser.com today, in OS X and the current Ubuntu linux distro. ABP and filters are up-do-date, the following running: EasyList, Malware Domains, Fanboy's Social Blocking List, EasyPrivacy, and "Allow some non-intrusive advertising unticked" (thus, blocked). Looking closely at the OS X screenshot, Adblock Plus has even blocked 4 elements on the adsupplyads.com page-under, but did not block the page-under itself. Bear in mind when checking newser.com, the page-unders and floating banners do not necessarily re-appear once they've displayed, unless site preferences are cleared and the site is browsed some more.
Here's one additional screenshot, this one in OpenSuse 13.2 GNOME edition. This one, ABP and EasyList just installed, only the EasyList filter set active and non-obtrusive advertising allowed (stock install of ABP). As you can see in the linux screenshots, either the ad images for the floating banners are failing to load, or ABP/EasyList is catching those particular images and leaving the floating banner box; however, the particular OS X (MacKeeper) ad image loads through the EasyList filters. The adsupplyads.com page-under loads successfully through ABP/EasyList, triggered by random newser.com pages (but, again, only newser.com pages), regardless of computer, OS, or network used.
I don't know how it may be that you do not see the ads on newser.com, but I am able to reproduce them readily from various machines and OS's. Maybe they are location-specific? I'm in the U.S., and keiferschild is in the U.K. Perhaps the ads do not display to countries where English is not an official or dominant language, as it does seem to be a U.S.-based and -oriented site?
I don't see at all how these ads on newser.com could possibly be from adware/malware... OS X, Windows, Ubuntu, OpenSuse... If you have not done so, please go take a look at the demos on AdSupply's corporate website. You can see both of these sorts of ads demonstrated there (scroll down the page a bit).
