Message from webpage Trojan.worm Ransomware Infection

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

If you notice an application which starts to modify your browser settings and affects the way you surf the web, what would you do? Yes, you most probably you’d would like to find out what kind of software this is and whether it can do something harmful to your PC. Usually, the modifications that Browser hijackers such as Trojan.worm tend to impose are very obvious and also very annoying. They take place immediately after the application becomes part of your system. Letting the hijacker operate on your computer usually leads to automatic page-redirects to various sponsored websites, links, offers and ads of different types. New toolbars, search engines or homepage domains may also get incorporated and replace your preferred ones.

Obviously, this is something that most of the users won’t enjoy. It is also probably not the best idea to keep such software on your system and let it take control over your web surfing without asking for your permission. After all, if you are aware of the Internet threats, letting a third party application automatically redirect you to predefined web locations may hide certain security risks. For instance, if you happen to click on a misleading link, a contaminated piece of content, a sketchy website, an ad or a pop-up, you may land on some really nasty malware.

However, we need to clarify here that exposing you to computer viruses such as Ransomware, nasty Spyware and Trojans is not the goal of a piece of software like Trojan.worm. The primal purpose of such an application is to advertise and to earn revenue for its developers thanks to Pay-Per-Click ads or sponsored ads positioning. This explains the never-ending stream of commercials of various kinds that Trojan.worm tries to force on you. Still, despite not having malicious intentions, a hijacker may indirectly open up the way for other nasty threats into your computer if you are not careful with what you click on. That’s why, if you have such an application on your system, you should better try to avoid its redirects and sponsored ads until you fully uninstall it.

The Trojan.worm Ransomware Infection

Trojan.worm is a browser hijacker type of a security nuisance. Trojan.worm is categorized by the website redirects and pop-up ads it causes but it could potentially lead to even more serious problems.

The creators of browser hijackers and similar ad-generating or page-redirecting applications usually profit from the clicks and the site visits their software generates. That’s why, it is not surprising that most hijacker developers try to distribute and install these applications on as many computers as possible. For that, they use some very common and technically legitimate methods of installation known as “software bundling”. The browser hijacker usually becomes part of the system when the users download a software bundle (a set of applications, mostly free ones) and install it via the Quick/Automatic options without checking for optional or added components which might be included in the setup and could be potentially unwanted. Luckily, a simple click on the Advanced/Manual/Custom options can reveal these additional components and let you disable them from the bundle.
