    Hi all
    Recently I downloaded a disk image file[​IMG] from the internet which had some consequences.
    It installed MacKeeper[​IMG] and a HelperBar safari extension. Those are the files[​IMG] I could find. However, when I read articles on the internet, some words from that article are highlighted, to point out it's a link.
    Those links are something scam like, if you click on it they demand your phone number so you can download more content about the article. (see screenshots) It even does it in this thread (see third screenshot) I don't think malware is the right word but I can't find a better one.
    Anyways, this is caused by that same .dmg file. Where could the cause be hiding, if it isn't in the application folder or in the safari extensions section? Adblocking the thing doesn't help either. I downloaded 'Malwarebytes without any results.

    I thank you in advance



    I was able to block the ad with adblock. Though this is not a solution because it also removes the linked word (the word is part of the article). Any help still welcome.

    UPDATE 2.0

    I got rid of the problem by simply restoring a backup from right before downloading the dmg file.
    Take away message: don't download video players which claim they have the ability to play .wmv files. In this case the video player Movist, if I remember correctly.

    Download and run MalwareBytes for Mac. It will take about 2 minutes to sort out the issues. :)

    OK, could you try download Avast and run a full scan through that?

    Could you also screenshot your startup programs by going to System Preferences>Users & Groups>Login Items?

    Exactly what do you mean when you say MalwareBytes didn't work? -- You were unable to download it? You were unable to install it? You could install it, but it didn't run? It ran but reported no malware?

    Thanks @keysofanxiety, I had no idea that the product was available for OS X.

    (Side note: a couple of weeks ago the product for Windows didn't catch, on a colleague's Windows 7 notebook, a PUA that was subsequently caught by Microsoft Windows Defender. Still, I treat it as a utility of choice where malware and/or PUAs are suspected with Windows.)

    Lol what player did you try? Btw you had to approve the install.
    Anyways, use VLC player for all your video needs. It's free and no ads or malware And aka or very one has it on their mac. Great on iOS as well.

    MacKeeper, *shiver*, it's as terrible as the virus they claim to fix. Sorry you had to endure that.
    VLC is "the" media player. Ignore the rest.
