There are few actions which need to be performed, before QuizCrystal can work properly. The first thing is to set a task of installation in case of uninstalling, and to gain updating from the developer's website. The browser is the secondary target. Homepage and search system are changed. Properties of browser shortcut are altered and the systems which regulate the quantity of advertisement are switched off. Most browsers nowadays have a service that hides the unwanted ads, pop-ups, banners and other sorts of hype. QuizCrystal switches these features off, and you begin to notice that the amount of advertising in all new tabs is dramatically increased. In addition, to that the amount of ads has grown up observably, its quality has decreased. If the hijacker works on the computer for a week, user just can't browse the Internet because of pop-ups, hype and redirections in all browsers and sometimes even to turn on the machine. So, what is the meaning of this? All actions of QuizCrystal are serving the one object: to coerce the user to make a click. Viral links often lead to third-grade web-pages selling low-quality goods, or services. Those web-pages simply aren't visited by anyone aside from their developers, and the only chance for them is to bait visitors to the site with use of such tricks. Any effort to get anything from this website will summon great issues. We believe, you realize that QuizCrystal is not the good software to store in your system, and it needs to be deleted.

Advantages of different removal methods

 

How to protect the computer?

To prevent these issues in the future, you have to know for sure how QuizCrystal got on your system. This can happen through three main methods:

  • Download from a malicious web-site. Some web-pages spread the malware without any precautions. The promises of suchlike programs are usual, they are: the improvement of Web surfing, acting installation of all drivers and updates for your devices, the performance of some actions in Facebook, showing the latest unpaid content such as music, games and movies, search for advantageous deals on the Net. All of these functions are already integrated into the browsers, or is in the Windows tools list, so, it means that these tools are absolutely needless, and the website that disseminates them is, most likely, dangerous.
  • Viruses may be attached to reliable programs. If you have ever downloaded the toll-free programs, you understand what that means. You download the program, and then you see the window with the proposal to install the miraculous file manager, removal tool, browser, the new add-on for it, and God knows what else. There's no need to make a decision because the installation has already been confirmed, and in some cases, it is really hard to cancel the installation of suspicious software.
  • In some cases user installs malicious software by his own will. Clever written description of the software and its brilliant (and nonexistent) features misinforms the user, and he installs malware.

The penetration via viral e-mail attachment is also extremely popular, but this way is used most of the cases by ransomware and viruses, and not by adware. We suppose that when you're reading these words, QuizCrystal will be totally removed from your workstation. If you prefer the hand uninstall, you should know how to realize that there is a virus on your workstation.

  • Slow launch of OS. The processes that run at startup are, in most cases, the reason of long boot. Check the taskbar, and delete the unwanted programs from Control Panel.
  • Appearance of ads in on every site. If the amount of ads increased noticeably - that is, most likely, virus.
  • Critical faults while using tools, shutdown or reboot of a workstation without your consent.
  • You see a lot of software which you haven't installed. If the program appears on your computer without your consent - it's, nothing else than the virus.

If you notice one of the described above symptoms on your machine - you need to perform an overall scan with assistance of anti-virus, or manually uninstall all the undesired and malicious software from your PC. Don't trust in everything you see on the Web, watch at the status of your machine, and it will be ready for any work.
