How to remove “ads not by this site” in Firefox.?

Asked by: 669 views Computer Security

Before upgrading to Firefox 11, I noticed big flashy banner ads across the top of my browser. I then installed “Adblockplus” and it blocked the ads, but there’s a big gray space still there as if it is designated for the ad banner. I used malwarebytes, Kaspersky Internet Security Scan, Spyware Doctor, and it is still there. I turned off adblock plus, and ads come back, I turn adblock plus On, it blocks, but I still see “ads not by this site” in that gray area for banner (not supposed to be there).

So does anyone knowHow the hell can I get rid of this browser hijacker? I even tried uninstalling Firefox completely with an uninstaller like Revo uninstaller to see if it gets rid of it. And then I didn’t use firefox for 2 months. I then recently installed Firefox 11, and I still have the same problem. I don’t know what it is, but at first my browser home page was hijacked by conduit search. I got rid of that, but I believe there is still left adware of this because recently, I just got a new problem called “Download N’ Save” Coupon scheme telling me a new way to save money, this appeared on my Ebay page now and don’t see it any other browser except FireSux.

    In most cases i’d say reinstall firefox and your ad-ons, but considering you already did that, just install and use Google chrome (Windows) or Safari(OS X)

    Your computer is infected with malware. That’s not Firefox’s fault, it’s yours. Give Malwarebytes a try and look up information on your particular infection to see how to actually get rid of it.

    You had better have an antivirus software on your PC.

    Anvi Smart Defender can proactively remind you this kind of serious thing.

    Any adverts you see will not be from or because of a Firefox update.

    Have you got ask.com software installed, could that be part of the problem ?

    and if necessary Cannot uninstall an add-on

    Consider installing some sort of ad blocker https://addons.mozilla.org/en-US/firefox/search/?q=ad+blocker&appver=11.0

    Try “MalwareBytes” to start cleaning up your system:
    http://www.malwarebytes.org/
    (free version has no “real-time” shield)

    See if this won’t help:
    Right click the Adblock Plus icon> Filter Pref’s> Custom filter tab> Element hiding rules> tick “Enabled”> Close.
    Then right click the offending block, and see what options ABP has for that. Select the most appropriate action. Mine has been the bottom checkbox, but yours may be different.

    I don’t think it’s a hijacker or malware; it’s just the space that’s been allocated from the html source, likely 3rd party.

    Do you also have these mod’s?
    FIREFOX: Tools> Options> Privacy> top drop menu set to “Firefox will use custom settings…”> Check ‘Accept Cookies from sites’
    ►Un-Check ‘Accept 3rd Party cookies’.

    ►►”NoScript” add-on, which constrains automagically fetching & deployment of potentially tainted assets.
