Your PC Has A Trojan

Your PC Has A Trojan

“Your PC Has A Trojan” is an unwanted piece of software that experts put under the browser hijacker category because of its ability to make undesirable changes in the main browser. “Your PC Has A Trojan” is compatible with Chrome, Firefox, and other popular browsers and usually gets installed without the user’s knowledge.

The “Your PC has a Trojan” Virus will display pop up ads and windows

Unlike harmful and stealthy forms of malware such as Ransomware, Spyware, or Trojans, browser hijackers like “Your PC Has A Trojan” do not attempt to keep their presence in the system hidden from the user. They may get installed into the browser in silence but once they are there, you will find out about it very soon.

The “Your pc has a trojan” notification

The moment “Your PC Has A Trojan” notification is added to the main browser on the computer, certain changes would start to occur in the browser – the default search engine would likely be replaced, a new homepage address would be added, sudden page-redirects and ads would begin to pop-up on the screen, other unusual and obstructive browser behavior may also be noticed.

Many users who have never before dealt with a similar app may mistakenly conclude that their system is under the attack of some harmful and damaging computer virus. This, however, is not the case when talking about hijacker apps. While certainly unpleasant, intrusive, and, sometimes, unsafe, those pieces of software are not specifically designed to cause harm to the system or to any of the files that are stored on the computer. Instead, the aim of hijackers like Captcha Source Center, iStart Search Bar is advertising-oriented – their creators are paid commissions for the content that the hijacker promotes by the people who own that content. That is why most hijackers are programmed to be as obnoxious and as “in-your-face” as possible as this ensures that they get more clicks on their ads and visits to the sites that they promote from the end-users. In some instances, to appear more desirable, some hijacker applications may have functions that the user may find appealing and useful. However, most of the time, there’s nothing that could make up for the endless frustration that is caused by the constant spam with ads, the seemingly irreversible changes in the browser, and the aggressive attempts to redirect the user to sites that the latter doesn’t want to visit.

The real problem with browser hijackers

While most of these apps are undoubtedly extremely annoying and obstructive, there’s a bigger problem that can be related to them and that is the potential security hazards that their presence on the computer may result in. In most cases, you simply have no way of being sure that what’s behind the ads and the redirects is safe and isn’t some harmful download link that will land you a Trojan Horse or a phishing page that will try to steal sensitive data from you. The content promoted by hijackers may not always be what it seems and that is why you are advised to keep away from it. Otherwise, you may end up with dangerous viruses like Ransomware, Spyware, Rootkits, and others on your computer. Obviously, the best way to stay away from the content that “Your PC Has A Trojan” tries to put on your screen is to remove the hijacker, which is something we will help you do within the following “Your PC Has A Trojan” removal/uninstallation guide manual.

    Hold the Start Key and R –  copy + paste the following and click OK:

    notepad %windir%/system32/Drivers/etc/hosts

    • After you complete this step, the threat will be gone from your browsers. Finish the next step as well or it may reappear on a system reboot.
