Researchers have labeled E.tre456_worm_osx a browser hijacker. Security problems such as E.tre456_worm_osx are known to cause website redirects, intrusive advertisements and even phishing attempts.

E.tre456_worm_osx is not a virus that needs to be removed but a rather annoying piece of ad-generating software. There are many programs that share the same behavioral patterns of E.tre456_worm_osx and all of them fall into one software category called browser hijackers. The target of such programs is not to cause you some type of harm (the way that some nasty virus, a Trojan or Ransomware infection would do) but to aggressively redirect you to certain sponsored web pages and generate various commercial materials such as ads, pop-ups, banners and intrusive sales offers. Implementing some changes in your default browser is the main way for the browser hijacker to land you on the advertised website or make you click on the sponsored ads. A remuneration model called Pay-Per-Click turns every click into income for the developers of the hijacker and their strive for more money is what justifies the ads disturbance that hijackers like this may cause. That disturbance, however, may seriously interrupt your normal web surfing and may make you really wish to remove the annoying ads and uninstall their source once and for all.

Real viruses like Ransomware, Trojans, Spyware and other harmful infections usually infect you secretly. E.tre456_worm_osx, as well as any browser hijacker in general, cannot do that. This software needs your permission to become part of your system. However, it still has its tricks to make you agree. For instance, most ad-generating programs are often distributed along with some other attractive software, especially free bundles, automatic installers and free new application setups. The moment you download and run such an installer, you may not be clearly notified about the presence of the additionally bundled browser hijacker and may agree on the standard installation option just as you do with any other software. That’s why you need to pay special attention when installing new programs and carefully customize their setup by using the Advanced/Custom/Manual option of the installation wizard instead of the standard/ automatic one.

Still, some users may really consider E.tre456_worm_osx as a source of intolerable ads-related disturbance and for this reason, they may wish to remove it from their system.  Replacing your homepage or search engine, exposing you to different intrusive ads and pop-ups, and constantly redirecting you to different pages and making you click on various intrusive ads is indeed activity that could be quite disturbing. More often than not, the browser hijacker may also keep track of your web activity and collect “traffic data” for its advertising purposes. This could also be seen as a form of privacy invasion and a good reason to uninstall the annoying software from your computer.
