Value Know is a browser hijacking application for Mac, which promotes sponsored websites by hijacking browsers and redirecting users’ searches. Value Know adds new browser features, such as new browser toolbars and buttons and places a new homepage and/or search engine.
Value Know can take over almost any popular browser including Firefox, Chrome, and Safari since they are some of the most commonly used browsers that Mac users utilize. But, this doesn’t mean that if you are using another web browser, it won’t be targeted by Value Know. This browser hijacker can easily alter its settings as well.
The main objective of such software is to benefit its creators financially. This happens through sponsored redirects to specific web pages and through the generation of various aggressive ads, pop-ups, and banners during the users’ web browsing sessions. The more people are led to the advertised pages, the bigger the pay-per-click profits received by the creators of the browser hijackers. This is the overall behavior of applications of this type.
Value Know for Mac
Value Know for Mac is an ad-generating application that tends to hijack Mac browsers in order to reroute user searches to the pages it is intended to promote. Value Know for Mac is able to modify the browser’s settings by integrating helper components such as a new search engine, a sponsored homepage or some quick redirect buttons.
For example, the new search engine placed in your Mac browser by Value Know may automatically display some sponsored websites every time you search for something on the web. Or, the new homepage that has been placed now automatically opens a pre-defined URL the moment you start the browser. As a result, you may find it difficult to navigate past those sponsored pages and find the real search results you are interested in. Besides, you may frequently get interrupted by dozens of pop-up ads during your web surfing sessions and find yourself stuck in attempts to remove them from your screen. Not only can this be very annoying, but also, sometimes, the ads and the websites to which you are rerouted may mask phishing pages or hide threats, such as Ransomware viruses and Trojans.
