What is all this browser-redirecting activity for?

The main purpose of browser redirecting software applications such as Concreasun.info is to aggressively advertise different products, services, offers, tools, search engines, websites and promote them in such a way so that you eventually click on them and buy something. The people who create browser hijackers typically gain profits from that advertising activity based on clicks/visits which is why they try to display as many ads as possible on the users’ screens. In order to ensure that you click on the right commercials – the ones that bring them profits, the advertisers often include certain redirecting components inside their software which automatically lead you to the items which are promoted. If you are wondering whether such redirecting practices are legal, we should tell you that in the majority of cases they are not against the law. Typically, the online advertisers rely on various intrusive and sometimes even aggressive marketing tricks to get their ads displayed but their intentions are normally not malicious. Unlike the criminal creators of computer threats such as Ransomware, Trojans and other viruses, the people behind programs like Concreasun.info are software developers whose sole interest is to promote different products and gain revenue from that and not to cause harm to your computer or your privacy. However, in the majority of cases, their software and the ads and redirects it generates becomes a source of unbearable browsing irritation, from which most users desperately want to get rid of.

Common issues, caused by Concreasun.info and similar browser hijackers:

Referring to browser hijackers as viruses, as we said above, is not correct. These pieces of software do not typically contain malicious code and are usually not designed to cause any type of harm, corruption, destruction or personal/professional data theft on your machine. In fact, unlike sneaky threats such as Trojans or Ransomware, they are not even able to “infect” you without your permission. This, however, does not mean that you are not going to face certain issues which may be a result of Concreasun.info’s ad-generating and redirecting services. For instance, apart from the annoying ads that we already mentioned, some hijackers are known for slowing down the affected browser and making it unresponsive to the people’s searches. There are cases in which the users are not able to go to the webpage they want to visit and are instead forced to deal with an endless stream of redirects, some of which may mislead them into clicking on malicious or compromised links, pop-ups or websites. A browser-redirecting software like Concreasun.info may also try to collect information about its users based on their web activities, likes, shares, recent searches and bookmarks and then send this data to its developers or to third parties. This activity is typically launched in the background and may not only be seen as yet another aggressive form of marketing research but also as an indirect invasion of your privacy, which may also eat up a fair share of your system resources.

How to avoid page-redirecting software in future?

The lack of attention during installation of software is the main reason for many users to end up with browser hijackers on their PC. Typically, programs like Concreasun.info could be downloaded and installed on your computer via different free installers – mostly software bundles, automatic installation managers, torrents and similar packs, which contain attractive games, free versions of new programs, optimization tools, converters etc. That’s why, in order to avoid them, make sure you abstain from downloading software from torrent platforms, freeware or shareware sites, and always use the Advanced/Custom/Manual installation options if you need to install any particular program on your PC. This way you will be able to leave out any potentially unwanted components before they become part of your system and will save yourself from the need to uninstall them later.
