The goal of this app is simple – to gain more views for certain websites and more clicks on the ads they show. The developers of this application get paid based on the Pay-Per-View and Pay-Per-Click models, which means that the more visits and clicks they get on the sites and ads promoted by their browser-hijacking tool, the higher the revenue they’d eventually earn. This is the main reason why the presence of Division Format in your Safari, Chrome, or Firefox is associated with the generation of aggressive ads and site redirects.

Division Format for Mac

Division Format for Mac is a homepage- and search engine-hijacking application that will use those elements of your browser for its site-promoting agenda. Division Format for Mac will not stop trying to put more ads and site redirects on your screen for as long as it remains active.

The worst part about all this, however, is not that the intrusiveness and irritation that this app could cause. Sure, the constant bombardment of your browser with site-promoting ads and redirects could be very unpleasant but what’s even worse than that are the potential external risks to which your Mac may get exposed should the hijacker stay in the system for long. There are way more dangerous threats out there, such as phishing viruses, Trojans, Spyware, and Ransomware, and if Division Format keeps causing your browser to get suddenly rerouted to unknown sites, it’s possible that some of these sites may contain such threats within their pages. Therefore, if you wish to avoid any unpleasant encounters with Ransomware, Trojans, or other dangerous forms of malware, it’s best to secure your Mac by uninstalling the browser hijacker that’s currently attached to your main browser.

What is Division Format?

Division Format is an unwanted software tool designed to generate advertisements and site redirects within the browsers of Mac users. Division Format will also scan the recent history of the browser to figure out what types of products and sites the user may be interested in.

This could sometimes serve to provide you with more relevant ads and show you offers you may be interested in. However, the information extracted from your browser may eventually be sold to third parties you have no information about, who may use the acquired data in ways you wouldn’t be okay with. Besides, you won’t be able to have any control over if or what data gets collected from your browser by the hijacker.
