Does Mac Mechanic pose a risk to your system?

Most of the applications like Mac Mechanic promote themselves as free tools which can make the users’ browsing experience more pleasant, safer and more relevant. However, in most of the cases, the real functions of this software are a bit different. The hijackers are tools which are created to serve the online advertising industry and they are usually set by their creators to generate income and traffic through the use of popular marketing methods such as Pay-Per-Click, automatic page-redirects and sponsored ads positioning. These methods are actually what creates disturbance and irritation to the users because they oftentimes may worsen the browsing experience by exposing the users to an unusually high amount of ads, pop-ups, sponsored messages and promotional websites.

But can such applications and their marketing methods be harmful? In some instances, the security of the computer may indeed be compromised, but this is not a result of some direct harmful activity. Luckily, the page-redirecting and ad-generating applications like Mac Mechanic have not been detected performing destructive or criminal actions on the users’ system so far which is why they cannot be put under the same malicious category as the real computer viruses. The hijackers are known as potentially unwanted apps and not as something that’s actually malicious. Still, some users seek to uninstall them from their computers because they fear that such applications may redirect them to some nasty virus-inflicted pages or get them contaminated with Ransomware, Spyware and similar dangerous threats. In theory, if you are not careful with what you click on,malware contamination could indeed occur, so it is generally always safer to avoid clicking on all the pop-ups that may appear on your screen.

How to avoid Hijackers?

The creators of page-redirecting marketing tools such as Mac Mechanic use many methods to have get their applications installed on the users’ machines. Usually, they distribute the hijackers as free download tools and browser add-ons which come as a bonus or added components to another program. Oftentimes, they bundle the page-redirecting software with free games, different optimization tools, PDF converters, document readers, free audio or video players or other new and interesting applications. When the users download such bundles, they usually don’t pay attention to the installation menus and simply agree on all the Terms and Conditions which oftentimes could include the installation of some undesirable component such as a hijacker. As a result, apart from the main application they desire, they may install applications like Mac Mechanic in the form of bonus components.

Fortunately, all the “bonus” components can easily be removed from the main installation package right before they become part of the system. For that, you don’t need any special computer skills but just a little bit of attention and the right installation settings. Just carefully read the Terms and Conditions when running a new setup and check the installation wizard for potentially unwanted applications which might have been pre-selected for installation by default. Use the Advanced or the Custom settings for manual customization of your installation preferences and remove any related checkmarks that might allow the installation of something that you may deem unwanted. This way, you can not only prevent annoying browser hijackers from getting on your PC but you’d also improve the overall safety of your machine and of the data that’s on it.
