How to remove Gnoosi.net redirect – Removal Instructions

Gnoosi virus (Gnoosi.net)

The Gnoosi virus (also found as GnoosiToolbar virus; though not technically a virus) is potential malware categorized as a browser hijacker and spyware that primarily installs to a Microsoft Windows computer and attaches to Google Chrome, Mozilla Firefox, and Microsoft Internet Explorer as a browser add-on, browser helper object (BHO), and extension without user consent. The GnoosiToolbar add-on and extension or item used to promote gnoosi.net changes internet browser settings including the home page and default browser search engine. This causes affected browsers to redirect to gnoosi.net and search.yahoo.com and startup on gnoosi.net when users open a new browser window or tab.

Gnoosi virus

Once software used to promote Gnoosi Search Engine is installed (such as GnoosiToolbar) the application will begin to replace existing internet browser settings, install additional software, and collect sensitive user information including data manually submitted online such as your name, home address, telephone number, email address, browser activity and history, and more. Gnoosi malware may also collect information when GnoosiToolbar is uninstalled and use additional techniques to collect purchase information or persuade victims to purchase sponsored and/or non-beneficial software.

If software that causes your browser to redirect to http://www.gnoosi.net is installed on your computer system and attached to your internet browser you are at higher than usual risk of cyber crimes involving credit theft, extortion, identity theft, and others. Even though these crimes are rare, this particular category of malware leaves users at a much higher risk if the software was never introduced to the computer system.

Gnoosi.net displays sponsored search results and redirects results to search.yahoo.com. The search engine is not considered a legitimate standalone service.

How does Gnoosi malware get onto a computer?

Items used to promote the gnoosi.net redirect virus such as GnoosiToolbar (Gnoosi Toolbar) can be manually and voluntarily installed from a variety of questionable websites including download.com. Gnoosi.net software or script used to transform browser settings to accommodate the search engine often bundles with suspicious third-party freeware and shareware.

Some users are given the opportunity to accept or decline an offer to install GnoosiToolbar and change their home page and search engine to the Gnoosi search engine; However, the user request to decline the offer is often ignored or represented in a confusing manner by the developer or distributor.

If GnoosiToolbar malware is installed, there is likely additional third-party potential malware on your computer system. The gnoosi.net redirect item primarily bundles with third-party browser objects and software without user consent or knowledge.
