Are you experiencing unwanted advertisements and browser redirects on your Mac? You may be a victim of the UpperTheory adware. UpperTheory is a potentially unwanted program that injects advertisements into websites you visit and redirects your browser search queries. This guide will provide step-by-step instructions on how to remove UpperTheory from your Mac and restore your browsing experience.
Understanding UpperTheory Adware
UpperTheory is a malicious program categorized as adware. It hijacks your browser homepage and search engine, replacing them with its own and displaying unwanted advertisements. This adware operates through browser extensions or programs that modify your browser settings. Once installed on your computer, UpperTheory redirects your search queries through its own search engine, often using Yahoo Search for search results. It also opens new tabs in your browser to display advertisements for software, fake software updates, and tech support scams.
How UpperTheory Gets Installed
UpperTheory is typically installed by users, either knowingly or unknowingly. It is often bundled with other software or advertised through deceptive ads. Users may unintentionally install UpperTheory when downloading software from untrusted sources or by not paying attention during the installation process. Some free downloads do not disclose the installation of additional software, leaving users puzzled about where it came from.
