What is ChatZum and how to remove it safely?

ChatZum can infect a Mac several ways. Clicking on a “sponsored link”, a virus download is sent to your Mac, which can also come through email attachments, or downloading software that includes ChatZum in a malicious bundle.

Once ChatZum has infected your Mac, it presents unwanted adverts and popups whenever you are online or using messaging apps, or any other applications that connect to the internet.

What are the symptoms of ChatZum?

Unwanted adverts are annoying, although infected users have found that ChatZum goes several steps further. It will add the ChatZum Toolbar, similar to other legitimate plugins. Using this, it can steal passwords and keystroke data. ChatZum will also change your default search engine to search.chatzum.com.

ChatZum is browser agnostic. It can hijack macOS Safari, Chrome, Firefox and others, disguising its files similar to other browser plugins. When you have the ChatZum malware on your Mac it will create an unwanted avenue for other malware, viruses and threats to come through the adverts it displays and the browser plugin. It is also capable of modifying browser and security settings, making it a particularly nasty piece of adware to have on your Mac.

Other signs of an infection include being redirected to an advert after completing a web form, or new browser windows opening without you taking any action. Sometimes infected Mac owners have found that applications start running unexpectedly, or new programs are downloaded and start running that you didn't install. You may also find that your Mac runs slower than it did before the infection.

However, unlike some forms of malware and viruses, it isn’t quite as difficult to find and remove. Although hidden, the fact that it acts similar to other browser plugins means that the payload packages are easier to locate and remove, either manually or with a Mac clearer tool, or antivirus scan.

How to remove ChatZum?

This is something you can do manually, although to be sure you’ve effectively removed the problem you will need to go through several files alongside making changes in your browser settings.

#1: Uninstall from Safari

  1. Go to Safari > Preferences.
  2. Click on Extensions.
  3. Pick the Extension that you don't recognise to delete.
  4. Click Uninstall.
  5. Confirm that you want to Uninstall the extension.

#2: Remove from Chrome

  1. Open Chrome.
  2. Go to the Menu in your browser.
  3. Click on More Tools > Extensions.
  4. Pick the Extension that you don't recognise to delete.
  5. Click Remove.
  6. Confirm that you want to Remove the extension.

#3: Remove from Firefox

  1. Open Firefox.
  2. Go to the Menu in your browser.
  3. Click on the Add-ons manager tab.
  4. Select the Extension you want to remove.
  5. Click Remove.
  6. Confirm that you want to delete it.

Now that you’ve removed the extension from your browser, you need to search through several files to make sure ChatZum is no longer hiding in your Mac.

Go to the following files to clear out any trace of it:


/Library/Application Support/SIMBL/Plugins/SafariOmnibar.bundle

/Library/Internet Plug-Ins/uid.plist

/Library/Internet Plug-Ins/zako.plugin

/Library/Application Support/SIMBL/



It is also worth resetting your browser settings and making sure that the default search engine is restored to what it was before the highjacking.

Now, if all of that sounds like too much work, don't worry. Or if you aren't confident that ChatZum has gone, then there is another - quicker - way to make your Mac safe.
