Stocks Info shows up on a computer as a browser extension on Google Chrome, MS Edge, or Mozilla Firefox. Judging by the name alone, the app is meant to provide information about stock market prices. This might seem like a useful feature, as most extensions are developed to provide some type of benefit for the users. However, this is rarely true for browser hijackers, as their main goal is to alter web browser settings to expose users to as much commercial content as possible.
In order to do that, Stocks Info would change the homepage and new tab address to its own and redirect all searches to a different provider (likely, Yahoo, although this might differ depending on your location). At the top of search results, the app would insert various links that otherwise would not be present if the default search provider would be used.
