The We Have Detected a Trojan Virus Pop up is designed to scare you into thinking you computer is infected.

If you have discovered We Have Detected A Trojan Virus on your machine, there is no need to panic. This program is not a virus or malicious software that seeks to harm you or your computer. But in case you can’t find an explanation for the constant stream of ads, banners, pop-ups, and page-redirects this program has started to display on your screen or you cannot remove the new search engine or the strange homepage that We Have Detected A Trojan Virus has imposed on your Chrome, Firefox, or Safari browser, on this site, we’ll tell you all that you need to know and we will help you take care of this situation. We will provide a thorough removal guide to help you uninstall the irritating software and remove all the obtrusive ads and unwanted browser settings. Just make sure you read the article before heading down to the guide as you will find a good explanation of what a browser hijacker really is and how to deal with it. 

Judging by the constant stream of pop-ups, box notifications, banners, and unwanted browser changes a program like We Have Detected A Trojan Virus might spam you with, you may easily mistake such software for a virus that needs to be removed. But let’s first explain what the browser hijackers really are so you can better understand what they are doing on your computer and why they are doing it. Basically, these are online advertising programs and they act as software tools that directly display advertisements on the screens of the web users, seeking to gain revenue for their developers every time you click on any of the displayed adverts. This is possible thanks to a remuneration system known as Pay-Per-Click, which is fully legal.

So far, there is nothing disturbing about applications such as We Have Detected A Trojan Virus, except for the fact that they can be extremely annoying and that their ads may sometimes be misleading. For some web users, however, this alone is enough to make them decide to remove such software from their system. Another reason why anyone may want to uninstall a browser hijacker is that this type of software usually takes its toll on the performance of the computer. For instance, if We Have Detected A Trojan Virus stays long enough on your system, you may start to experience browser crashes, unresponsiveness, and general sluggishness of the system, which may be caused by the fact that the browser hijacker consumes quite a lot of system resources for its ad-generating and page-redirecting activity. And while this is not a major system risk, it can surely be an inconvenience in the long run.

Besides, being exposed to random pop-up messages and redirect links may hide some risks as well. What we are referring to here is the possibility of bumping into ads that have been infected with malicious virus code and that are used to spread Trojans and Ransomware. If you accidentally click on a compromised ad of this kind, you might land some highly damaging malware. And the worst part is that there will probably be no indication of it. This malware-distribution method is known as malvertising and is commonly used for spreading various online threats. Now, this is not to say that We Have Detected A Trojan Virus will deliberately generate malvertisements on your screen, but there is always a risk of landing on a fake ad hidden within the huge number of regular advertisement that you see on your screen. For this reason, we advise you to avoid engaging with any online ads and to get rid of the browser hijacker that generates them for the sake of your safety.

We get asked this a lot, so we are putting it here:
Removing parasite manually may take hours and damage your system in the process. We recommend downloading ComboCleaner to see if it can detect parasite's files for you. 

Click to Download ComboCleaner's Anti-Malware Scanner.

More information about ComboCleaner and steps to uninstall. Please review ComboCleaner's EULA and Privacy Policy. Keep in mind, only ComboCleaner’s scanner is free. If it detects a malware, you'll need to purchase its full version to remove it.

The first thing you need to do is to Quit Safari (if it is opened). If you have trouble closing it normally, you may need to Force Quit Safari:

You can choose the Apple menu and click on Force Quit.

Alternatively you can simultaneously press (the Command key situated next to the space bar), Option (the key right next to it) and Escape (the key located at the upper left corner of your keyboard).

If you have done it right a dialog box titled Force Quit Applications will open up.

In this new dialog window select Safari, then press the Force Quit button, then confirm with Force Quit again.

Close the dialog box/window.

Step2

WARNING! READ CAREFULLY BEFORE PROCEEDING!

Start Activity Monitor by opening up Finder, then proceed to activity-monitor

Once there, look at all the processes: if you believe any of them are hijacking your results, or are part of the problem, highlight the process with your mouse, then click the “i” button at the top. This will open up the following box:

chromeinfo

Now click on Sample at the bottom:

Step4

Re-Launch Safari but don’t forget to press and hold the Shift button while doing it, so no previous pages can be opened up. Now, Click on Preferences in the Safari menu,

and then again on the Extensions tab,

Step5

The threat has likely infected all of your browsers. The instructions below need to be applied for all browsers you are using.

Again select Preferences in the Safari Menu, but this time click on the Privacy tab,
Privacy in Safari

Now click on Remove All Website Data, confirm with Remove Now. Keep in mind that after you do this all stored website data will be deleted. You will need to sign-in again for all websites that require any form of authentication.
