What is Chromium Browser and is it dangerous?
Chromium Browser is not a virus: it is an open-source web browser developed by Google and contains the majority of Chrome browser’s functions. Open-source means that its program code can be taken and customized by anyone, therefore producing both safe and malicious browser versions and distributing them worldwide. Unfortunately, this is the reason why so many Windows and Mac users search for Chromium virus removal guides today.
Do not get confused – Chromium browser is legitimate and safe to use, but its spin-offs might not be. Sadly, there are many versions on the market today that can be installed unknowingly. In most cases, it happens when installing freeware from the Internet.
The reason why so many people start calling Chromium a virus, is that the creators of adware and browser hijackers quickly leveraged the possibility to easily create modified browser versions that would cause redirects or pop-up ads.
To be precise, they take open source codes and add specific functionality to them, making these browsers display third-party ads from various ad networks, or cause unexpected redirects to partner websites to generate revenue.
Unfortunately, such behavior is not acceptable and in the worst scenario can lead to malicious or phishing websites. In the best scenario, such activity can annoy the user, slow down the computer and interfere with daily browsing activities.
To determine whether you’re dealing with Chromium virus, consider checking this list of symptoms of possible infection:
Symptoms of Chromium malware infection
- Browser’s start page changed without your knowledge;
- Clicking on new tab opens a specific and unknown website instead of blank page;
- You notice pop-up and pop-under ads (these ads either appear on or under the window you’re currently using);
- You notice suspicious redirects when browsing online;
- New tabs open automatically and load promotional content;
- Noticeable computer slowdown;
- You cannot access certain programs, f.e., antivirus.
One additional check you can make is go to chrome://settings/help and check what kind of browser you’re using. If you discover that you’re using some suspicious browser which took over your default browser without your permission, you must remove Chrome virus immediately.
Common methods used to distribute rogue browsers
Fake Chromium browsers can be packed in software bundles, but you might also install them unknowingly. For example, you can get one after downloading not exactly legal files, or along with freeware such as file converters or download managers.
As a rule, some of the freeware installers tend to suggest extra items along with Default installation configuration. In such case, deselecting extra suggestions is essential step before hitting that “Install” button.
In general, we recommend staying aware of these techniques and never rush when installing new programs. However, you can also install them unknowingly and find that Chromium won’t uninstall that easily. If so, it could be that you installed a malevolent version of it which uses slightly advanced techniques to stay on your system, doesn’t have or hide its uninstaller, and etc. Typically, people start looking for help on forums like Reddit for help to get rid of it.
The easiest way to delete such browsers that take the privileges of the default browser is to remove them automatically, however, with some time and patience you can do it manually as well.
