How to remove Chromium virus on Mac?

Chromium is Google’s open-source web browser project. It’s not a full-blown web browser like Chrome, but a platform that allows third-party developers to build their own code and create their own browser. Unfortunately, not all of those developers are interested in creating a great browser. Instead, their goal is to infiltrate your computer with malware to steal your data. 

What is Chromium browser?

Chromium browser is any browser built on Chromium — a legitimate Google-funded project developers can use to write code. The difference between Chrome and Chromium is that Chrome is the finished Google’s web browser when Chromium is the framework used to build it.

How to uninstall Chromium from Mac

The easiest way that I found to uninstall Chromium once and for all is to use the Uninstaller tool in CleanMyMac X. It deletes not just Chromium but all its parts and pieces across the entire system. This is how it works:

1. Download and install CleanMyMac X — get a free edition here.
2. Choose Uninstaller.
3. Find Chromium in the list of apps or search for it in the search box.
4. Check the box next to it.
5. Click Uninstall.

That will remove every trace of Chromium from your Mac.

How to get rid of Chromium on Mac manually

Removing a legitimate version of Chromium is a piece of cake. Just find it in your Applications folder, drag it to the Trash, and then empty it. Obviously, that won’t uninstall it completely due to other related files located in folders, such as:

/Library/LaunchAgents

~/Library/Application Support

So, check these folders and drag anything Chromium-related to the Trash. Then, empty it and restart your browser. If you think you may have missed some leftover files, check out this article on how to completely delete apps from Mac.

If the version of Chromium you’ve installed contains malware, the process is a bit more complicated. But no worries, you can fix that, too. The next piece of this article will teach you how to accomplish that.

Remove Chromium and apps that it was bundled with

1. Go to your Applications folder and look for the app you downloaded just before Chromium appeared on your Mac.
2. Drag it to the Trash and then empty it.

You might also try removing Chromium from your Library.

1. Click Finder, then choose Go in the top menu.
2. Choose Go to Folder... Now, paste the following locations:

/Library/LaunchAgents
~/Library/Application Support
/Library/LaunchDaemons

Open these folders and look for files that have been added recently — you can use Column view in Finder and sort by Date Added to find them. If you find any suspicious recently added files, drag them to the Trash and empty it.

Delete the app from your Login items

Now, choose System Settings from the main Apple menu and click General > Login Items.

Look for any login items that look suspicious. If you see one, select it and click the “-” button.

How to protect Mac from the Chromium virus?

Now that you’ve removed Chromium from your Mac, you may want to ensure that no other malware sneaks onto it. The easiest way to do this is to run a full Mac virus scan. Basically, it is a good idea to run such checks every once in a while.

And guess what? You can quickly do it with the same app we mentioned earlier — CleanMyMac X. The application is equipped with the Malware Removal tool that blocks infected apps and “backdoor viruses” currently functioning on your Mac.

All you need to do is download the app for free and navigate to the Malware Removal tab in the sidebar. Then, click Scan to start the virus-removal process. If it finds anything, just click Remove, and you’re safe.

A quick recap: Chromium is not a virus. It’s not even malware. However, some scammers use fake Chromium builds to spread malware. To avoid installing a malware version, you should only download Chromium from the official website. But if you’ve already installed an infected version of Chromium, you can get rid of it by taking the steps we outlined in this article. Or you can use CleanMyMac X as an alternative solution. Stay safe!
