What is Infonaut

Infonaut is malicious browser app in form of extensions for Google Chrome, Mozilla Firefox and Internet Explorer. It also installs service and driver and starts displaying various advertisements (“Ad by Infonaut”, “Sponsored by Infonaut”, “brought by Infonaut”). This ads may be presented as pop-ups, underlined words, advertising sites opening in the new tab without user interaction. This is far from, what developers of this application promote – “enhancing your browser experience”. As this program installs service and driver it is rather hard to remove the regular way. Uninstall from Control Panel may not work. Read instructions below to remove Infonaut and its ads.
