For all we know we are wring to do this, the modification of homepage and search engine is part of its attack and we must accept its changes at the beginning because it has controlled the entire browser. But when we come to judge this program, it is not by which kind of virus it is, but what troubles it will cause on our computers. To take a trivial instance: when it is installed and then activated on our machines, this infection starts changing default start up page, homepage and search engine to its related domains. There is not much to choose when the browser is under its control. Since this is a site which providers search provider and start up page, it is not easy to say it is worse than most search sites, but we must know that if we set this site to be default, even sometimes we do not make the changes ourselves, our browsing activities will be affected from the pages we want to visit to the search provider we want to set. The knowledge that clicking on insecure links are dangerous to our browsing should make us realize us with computer protection as well as to the websites we are going to access.

If we gather the data from victims whose computers are infected by this threat, we may find that the computer which gets infected will run slower and weird than before as there might be a lot of backdoor processes which are running without being known. The affected machines which get numerous unwanted third party programs on system are said to be twice as likely to have other troubles after the system resources are used up, even after taking into account other factors. As a victim who gets infected, avoiding using infected browser does not help navigate these issues.


Keeping this program on system will generate more troubles, and inexperienced people can not get away from the infections. While we often associate virus with Trojan or Ransomware and avoiding these viruses attacks, we should note that browser hijack is also a kind of attack which may bring damages to computers. The key to avoid this kind of attack is stop downloading programs from the internet when we do not have any protection.
