LogFormula is a potentially unwanted program that injects advertisements into websites you visit and redirects your browser search queries. It is important to remove LogFormula from your Mac to protect your online privacy and ensure a smooth browsing experience. In this article, we will guide you through the process of removing LogFormula adware from your Mac.

What is LogFormula?

LogFormula is a malicious program that hijacks your browser homepage and search engine, displaying unwanted advertisements that do not originate from the sites you are browsing. It typically uses a browser extension or program to carry out these unwanted actions. When installed on your Mac, LogFormula will redirect your browser search queries through its own search engine, which in turn redirects to search result pages from Yahoo. This is likely done to generate advertising revenue by using Yahoo Search for its search results. Additionally, LogFormula opens new tabs in your browser that display advertisements promoting software, fake software updates, and tech support scams.

Common symptoms of LogFormula infection include:

  • Your web browser’s default search engine is set to LogFormula Search.
  • Your browser’s search queries are redirected through LogFormula Search.
  • The “LogFormula” browser extension or program is installed on your Mac.

How was LogFormula installed on my computer?

LogFormula is typically installed by users, either knowingly or unknowingly. It is often offered through advertisements or bundled with other software, leaving users puzzled about its origin. Some free downloads may not adequately disclose that LogFormula will be installed alongside the desired software, leading to unintentional installation. Malicious ads are also known to distribute LogFormula, tricking users into clicking on them and triggering the installation process.

If you are unsure how LogFormula was installed or suspect that other unwanted programs may be present on your Mac, follow the removal guide below to ensure a thorough cleanup.
