How to uninstall Dark Mode extension from Chrome, Firefox, IE, Edge

What is Dark Mode?

The cyber threat analysts have determined that Dark Mode is a rogue browser extension that belongs to the family of Browser hijackers. The aim of browser hijackers is to generate advertising revenue. Browser hijackers can redirect the user’s homepage to the browser hijacker’s page that contains ads or sponsored links; browser hijackers can redirect the user web searches to a link the browser hijacker wants the user to see, rather than to legitimate search engine results. When the user clicks on advertisements in the search results, the developers behind browser hijackers gets paid. The authors of browser hijackers can gather personal data such as user browsing habits as well as browsing history and sell this information to third parties for marketing purposes.

Most often, browser hijackers promote fake search providers by setting their address as the default search provider. In this case, the browser hijacker installs mktsrc.com as a search engine. This means that users whose web-browser is hijacked with the browser hijacker are forced to visit the mktsrc.com address each time they search in the World Wide Web, open a new window or tab. And since mktsrc.come is not a real search provider and does not have the ability to find the information users need, this web-site redirects the user’s web browser to the Bing search engine.

Another reason why you need to delete Dark Mode is its online data-tracking activity. It can collect confidential info, including:

• IP addresses;
• URLs visited;
• search queries/terms;
• clicks on links and ads;
• web-browser version information.
