What is Omnibox.bar? And how does it function?

Omnibox.bar is a browser extension that functions as a search engine that allows users to modify the wallpaper of its homepage.

If installed, Omnibox.bar will adjust the default search provider, homepage as well as the new tab URL. It could also install some unknown toolbars and add-ons in the browser which, once again, is done without your permission. After all these changes made, it now becomes easier for this browser hijacker to inject tons of ads into every website you visit online. So don’t be surprised if you suddenly see pop-ups, banners, in-text links and other sponsored content s you browse the web. This kind of practice is common for browser hijackers as it brings revenue to its developers via pay-per-click marketing.

Aside from that, Omnibox.bar also monitors all your activities on the internet in order to obtain information which may include your IP address, websites you visit often, search queries, browsing history and other data related to your browsing.
