PUA.BrowseFox is a Potentially Unwanted Application (PUA) not a virus. Most anti-virus programs use this detection to inform users about programs that are not malicious but still can cause problems or expose your system to threats. It’s a polite way of saying that one or more programs should be removed despite that they are not technically malware or spyware. Potentially unwanted simply means that you may find it useful or maybe you knowingly installed it on your computer but didn’t realize what it actually does. It actually happens all the time. Users don’t read End User License Agreements or other notifications about third-party programs like PUA.BrowseFox that can display ads on their computers. And indeed, this program usually comes bundled with adware and freeware. And if you don’t read EULA carefully don’t blame others when your computer suddenly becomes unusable. Unless, of course, it was installed without your permission.

PUA.BrowseFox is a browser hijackers that hijack your installed web browser’s home page and search engines so that they display the PUA.BrowseFox home page and search engine instead of your normally configured ones. When installed PUA.BrowseFox will modify your web browser’s configuration so that the home page becomes something new and it’s default search provider will become a PUA.BrowseFox search provider powered by Yahoo. What makes this hijacker so problematic is that it uses Windows services to make it difficult to change your browser’s settings and also modifies your web browser’s shortcuts so that the PUA.BrowseFox partner site is always opened.

PUA.BrowseFox are installed by free programs that you download from the Internet that did not adequately disclose that other software would be installed along with it. Therefore, it is important that you pay close attention to license agreements and installation screens when installing anything off of the Internet. If an installation screen offers you Custom or Advanced installation options, it is a good idea to select these as they will typically disclose what other 3rd party software will also be installed. Furthermore, If the license agreement or installation screens state that they are going to install a toolbar or other unwanted adware, it is advised that you immediately cancel the install and not use the free software.
