Software like Chromnius typically disguises itself as legitimate and harmless, enticing users to download and install it by promising “handy” and “advantageous” functionalities. However, these functions rarely work as advertised and are often completely non-operational.

How did Chromnius get installed on my computer?

We downloaded Chromnius from its “official” download webpage, which turned out to be a deceptive site promoting this browser. Most users come across such websites due to redirects caused by mistyped URLs, pages using rogue advertising networks, intrusive ads, spam browser notifications, or installed adware with browser force-opening capabilities.

However, this type of software can also be distributed through other dubious and deceptive methods. “Bundling” is a marketing technique that involves pre-packaging regular installers with unwanted or malicious additions. Downloading from untrustworthy sources like unofficial and freeware sites, Peer-to-Peer sharing networks, etc., and rushing through installations using “Quick/Easy” settings increases the risk of allowing bundled content onto your device.

Intrusive advertisements are another common method of proliferating unwanted software. Clicking on these ads can trigger scripts that stealthily download and install the software.

How to avoid installing unwanted applications?

We strongly recommend researching software and downloading only from official and verified channels. When installing software, it is crucial to read the terms, examine available options, use the “Custom/Advanced” settings, and decline all supplementary apps, extensions, etc. Vigilance is advised while browsing, as fraudulent and malicious content often masquerades as legitimate.

If you encounter the aforementioned ads/redirects, inspect your device and promptly remove any suspicious applications, browser extensions, or plug-ins.
