Chromnius.exe adware in detail

Chromnius adware is based on the Chromium technology platform. It can display banner ads, full-screen advertisements, pop ups, videos, or other varieties of online advertising. Maybe you approve the idea that the ads or pop-ups are just a small problem. But these unwanted advertisements eat computer resources and slow down your web-browser performance.

Chromnius uses its own website as search engine. This means that users who use it as a web browser are forced to visit this website each time they search in the Internet, open a new window or tab. And since this website is not a real search provider and does not have the ability to find the information users need, it redirects the user’s web browser to Google, Bing or Yahoo search engine. The devs behind Chromnius are most probably doing this to generate advertisement money from the ads shown in the search results.

Is Chromnius safe?

Like other adware of that kind, Chromnius is able to monitor and report on your activity and provide information to a third party. Adware can install a component (spyware) that enables its creators to track which web pages you visit, what products you look at upon those pages. They are then choose the type of ads they show you. So, if you have adware installed on your personal computer, there is a good chance that you have another that collects and shares your sensitive information with third parties without your consent.

Attackers often use adware to redirect users to malicious and scam websites. Below are some examples of such sites:

To summarize, the adware can lead to malware infection and financial losses. It can seriously affect your privacy, your computer’s performance and security.

How does Chromnius get on your computer

Most adware gets installed when users visit an infected website, download a malicious app, or click on a link or an attachment, install freeware that includes a bundled program.
