GigaPromo Virus


GigaPromo is a small software app that gets put inside users’ browsers and aims to promote certain sites and ads through aggressively redirecting the browser to them. GigaPromo, on its own, is not harmful, but the content promoted by it cannot always be verified as safe.


The GigaPromo virus generally speaking is to produce all kinds of intrusive pop-up advertisements

Web adverts have the ability to become a trouble for any PC that has GigaPromo installed in it. The reason for the ads that are likely currently swarming your screen is likely this exact annoying software as it has recently included itself inside your computer and, more specifically, in your browser. The category of of software to which GigaPromo belongs is the Browser Hijacker one – a type of apps that are widely regarded as undesirable. In this post, you’ll obtain the information required to get rid of GigaPromo from your own machine as well as guidelines on the best ways to guard your computer from apps like this one in the future.

A needed comparison

The primary aim of GigaPromo and Captcha Smart browser hijacker programs generally speaking is to produce all kinds of intrusive pop-up advertisements and page-redirects that usually seriously hamper your usual internet experience. To be able to generate the adverts on your browser, the browser hijacker integrates itself inside your browser, typically by functioning as an add-on or an extension. But what exactly is the point of all the ads? Obviously, a lot of people spend more time in front of a computer screen rather than in front of a TV screen – browser ads are, without a doubt, one of the most profitable forms of marketing at the moment. The Browser hijackers are usually legal software applications, specially developed to fulfill the purposes of the web marketing and are used for generating adverts and carrying out various telemetry data gathering activities to help the marketers sell their products and services with greater effectiveness. The browser hijacker are often rather aggressive when showing adverts and the more aggressive types of browser hijacker are going to cover your screen with adverts, preventing you from using the computer up until you click on at least one of the banners, pop-ups or box messages.

Generally, the browser hijacker pieces of software like GigaPromo are mistakenly categorized as malicious infections by misinformed users. Regardless of their unnerving nature, however, software applications of the browser hijacker sort are very different from any actual type of computer malware. Malicious software such as viruses, Trojans and the growing in popularity Ransomware, are the real threats that people should be concerned about.

The spam of unwanted commercials is certainly the primary goal of apps of the hijacker type. After all, this is the main source of income that these apps can provide their creators with. Here is a basic representation of how the ads from hijackers actually make money – a customer clicks on an ad and the company behind the browser hijacker gets paid on a pay-per-click basis because a certain product out there got promoted and the chances that this product would get bought have increased. The browser hijacker is created in a way so that it links the banners to the sites of the third-party companies that are its partners. Browser hijacker programs, despite what many people may presume and despite how annoying those apps may be, tend to be a completely permissible method of promotion. Frequently, browser hijacker applications get bundled with freeware after a certain payment is made to the freeware’s creators. This is, in fact, how most apps like GigaPromo get distributed.
