The settings that software of this type typically affects have to do with the browser’s homepage and the default search engine. A piece of programming like Weknow will normally introduce its own search engine as your new default one and will probably set the same as your new homepage as well. This is done with the intention of promoting said page, as well as exposing users to a variety of sponsored web content.

Weknow for Mac

Weknow for Mac is programmed to generate substantial amounts of popups, banners, box messages and other ads during your browsing sessions. Thus, Weknow for Mac is essentially an elaborate tool for advertising.

However, while it may seem relatively harmless at first, there are background processes that Weknow may be running that may make you want to remove it as quickly as possible.

Despite being considered a potentially unwanted program, Weknow is not a virus. Weknow cannot cause any real harm or damage to your Mac computer. Unlike real malware such as ransomware and Trojans, a browser hijacker is only intended to generate revenue for its developers by promoting various products, services and websites.

  • I kept trying the steps here and everywhere I could find them and while I was certain that I had removed the local adware/malware my Chrome browser STILL would default to WeKnow and every time I opened Chrome it added another reference to WeKnow in my search engine list. One of which was always dark bold font and could not be removed or successfully edited.

    Ultimately, I found a reference (link below if you want to read the thread, but I’ve put the steps here to make it easy) to the fact that the malware makes changes to your Chrome policies (you can see them by typing chrome://policy into your chrome browser). You can fix the problem by doing the following:

    1) Open your Terminal application (easy way is type “Terminal” into your spotlight search and hit return, OR open your Applications folder, open the Utilities folder in that folder an double click the “Terminal” application in that folder.

    2) Copy and paste each of these lines into the terminal application window at the prompt one at a time hitting return after you paste the line in.

    3) Restart your computer and open Chrome.

    4) Smile and have a drink.

    • Use the command line to delete / modify the affected policies. You do this by opening up “Terminal” and copy and paste each of the following entries below. I did each one at a time. I copy and pasted the first line and then hit enter and then went to the next until I had finished all 6 below:

      defaults write HomepageIsNewTabPage -bool false
      defaults write NewTabPageLocation -string “”
      defaults write HomepageLocation -string “”
      defaults delete DefaultSearchProviderSearchURL
      defaults delete DefaultSearchProviderNewTabURL
      defaults delete DefaultSearchProviderName
