Dark It Online browser extension (virus) - Free Guide

What is Dark It Online browser extension?

Dark It Online can inject advertisements into the search results and cause redirects

Dark It Online can cause the browser to behave erratically

Unlike many other browser hijackers,^[1] Dark It Online actually delivers on its promises. The ability to provide a dark mode for websites is functional. We previously wrote about other browser extensions that promise the same thing but are completely useless, like Mini Dark, Moon Darker, and Real Dark.

However, you should not cheer just yet. It was discovered that this application may inject advertisements into the search results and change the main settings, like the homepage, new tab address, and search engine. It might also cause an increased amount of commercial content, like pop-ups, banners, and redirects.

Even though the application does what it says it will do, keeping it in your system may be dangerous. Crooks often use rogue advertising networks that place ads leading to suspicious websites. People may be tricked into providing their personal information, downloading PUPs (potentially unwanted programs),^[2] and even malware.

Distribution techniques

Usually, fraudsters use unsecure sources to spread applications like Dark It Online. This includes fake “Downloader” pages and sites that use social engineering techniques. Nowadays, crooks do not need to have any hacking skills. All they have to do is come up with a convincing message and image.

This browser extension was found to be spread through a bogus site that looks like it has a video to play. It also displays a deceptive message:

Please use a extension to access blocked sites and view videos anonymously.

You should never download anything from random pages. Your browser should also never block any content so if you see this or similar messages, you should exit those pages immediately.

Dark It Online is spread through shady download pages

You should also keep in mind that even though we always recommend our readers to use official web stores, sometimes hijackers slip through the extensive review process. That is why doing your research is important. Read the reviews, look at the ratings, and the number of users an application has. It is best to choose those plugins that have plenty of positive feedback and thousands of users.

Delete cookies and cache to protect your privacy

Cookies^[3] are small pieces of data that are used to include all sorts of settings. While they are not malicious by themselves, they can be stolen by third parties and used for malicious purposes. Therefore, security experts advise cleaning web browsers regularly. You can employ automatic cleaning tools such as FortectIntego, although you can also refer to the manual instructions below.

Freeware distribution platforms

The hijacking could have been caused not only by a browser extension but also by a PUP (potentially unwanted program). If the previous removal method did not get rid of unwanted symptoms, this step should fix it. Adware usually hides in the background of the machine performing unwanted tasks without the users' knowledge.

Most times adware gets installed from freeware distribution sites. Because they do not make any money from giving away software for free, they include additional programs in the installers. Many users find the installation process boring so they skip through the steps and do not notice the additional files.

You should always choose the “Custom” or”Advanced” installation methods, read the Privacy Policy and Terms of Use to find out what the program will be capable of. The most important step is to check the file list and untick the boxes next to any unrelated applications.

Scan the system with anti-malware tools

Identifying the program responsible for hijacking your browser might be difficult if you have never done this before. Fraudsters like to disguise them as “handy” tools, so they could look like an antivirus suite, image editing software, media player, system optimizer, etc.

If you are not sure what to do and you do not want to risk eliminating the wrong files, we suggest using SpyHunter 5Combo Cleaner or Malwarebytes security tools that will scan your machine, eliminate it, and prevent such infections in the future by giving you a warning before a malicious program can make any changes.
