What is Masterdeals?

Is the question ‘How to remove Masterdeals virus from my computer?’ is the only one that constantly comes into your mind these days? Have you already looked through various blogs and websites looking for the ways on how to remove this dubious application that keeps showing irritating advertisements during your browsing? If yes, then eventually you’re in the right place.

It seems that you have installed an adware on your computer and now suffer from marketing campaigns that it initiates during your browsing. Masterdeals is also known as a potentially unwanted program (PUP), which means that it’s distributed as a component of other freewares, not as an individual application. Therefore, if your web browser (Google Chrome, Mozilla Firefox, Internet Explorer or Safari) has started showcasing tons of pop-up ads marked as ‘Ads by Masterdeals’, probably you have just finished the installation of a download manager, PDF creator, media player or another popular free software, but, unfortunately, failed to perform it in a proper way. Next time, you should be more careful when installing freewares, opt For Advanced or Custom installation and deselect additional components, such as Masterdeals and its clones, including DealShark, eDeals, Windows Discount and many others.

Even though Masterdeals is not a virus, it may hide deep in PC’s system, use its resources, connect to the Internet without permission asked, download updates, cause slowdowns, security vulnerabilities, and similar issue. Even more, Masterdeals ads may redirect you to affiliate or sponsored websites quite easily. Usually, commercial advertisements are generated according to user’s browsing and search history, IP address, PC’s location, and other information that is stored on user’s computer. Therefore, those ads look really interesting and convincing. Thus, before clicking on the ads, keep in mind that Masterdeals redirects may force you to enter really suspicious websites (e.g. filled with PUP or virus installers). Therefore, if you want to prevent unwanted activities and maintain your PC’s security, we recommend initiating a full system scan with Reimage (Windows OS) or Webroot SecureAnywhere AntiVirus (Windows OS X) and removing this adware without any delay.

How can Masterdeals hijack my computer?

Masterdeals add-on is supposed to display useful coupons, comparison deals, discounts, and similar things in order to help you find a desired item for the lowest price. However, before installing it you have to be aware that it’s not that useful as promoted. Security experts have noticed that Masterdeals virus usually spreads as an additional component alongside other freewares and sharewares. Even if you are given an opportunity to agree or disagree with the installation of this adware, such distribution is treated as extremely unfair because propositions to install ‘additional components’ may be hidden or disclosed in a tricky manner. Thus, if you want to keep various intruders away from your PC, you should avoid clicking Next button all the time when installing freewares. In contrast, you should opt for Advanced or Custom installation, check the process step-by-step and deselect ‘optional components’.
