Essential details about browser redirect as a whole and in particular

It comes as no surprise that the term browser redirect represents the ad-producing software, which has been designed to show as many ads as possible. If you are wondering why such programs generate such an incredible number of ads, the answer is – because of the money they earn from those pop-ups, banners and tabs. Generally, the mere purpose of browser redirect is to increase the revenue of their developers as much as possible.

How does it get distributed?

In this paragraph we are going to discuss the potential means of distributing browser redirect. Actually, they may greatly differ from one another. However, the most commonly used ones are:

  1. By incorporating it into software bundles. Some programmers offer their software for free to the public but they may include browser redirect in the package in order to make some money for their further developing practice.
  2. By including it in torrents, shareware, spam emails.
  3. By clicking on suspicious links or even more suspicious websites that may redirect you to possible sources of browser redirect, and even malware (for instance, Ransomware);

Is Youndoo “virus” really a virus?

This is an important question. Most of our readers refer to youndoo as Youndoo “virus”. They are mistaken though. Technically Youndoo is neither a virus nor malware. Actually, you don’t have a real reason to worry. Browser redirect does NOT represent a security risk. It is not programmed to steal, destroy or encrypt anything on your PC as most viruses often do. Nonetheless, some of the practices their creators use may appear somehow shady to you, as browser redirect may be designed to track your browsing history and offer you only the ads matching your current searches. What’s more, it is possible that some of the generated ads may lead to potentially dangerous places with hazardous content. Also, sometimes the data about your search requests and choices might get sold to 3rd parties, most commonly vendors, who will use it to trick you into buying something from them.

We should also mention that the big number of displayed ads could substantially slow down your machine, because of the unusually higher consumption of system resources. However, chill out! There is nothing malicious and really dangerous about browser redirect that you should stress over!
