Sibelius6
Sibelius6 is a potentially harmful ad-displaying app for Safari, Chrome, and Firefox, that hijacks the browser’s settings. Sibelius6 may potentially inject ads into the search results and also replace the homepage of the affected browser with the aim to generate more ads.

If all of this sounds familiar and you’ve been having a similar experience as of late, then you may find the next article informative and helpful. The app that is tampering with the settings of your main browser and is causing unwanted changes and ad-generation isn’t exactly what can be referred to as a virus. It doesn’t seek to cause damage to the system or to compromise your data and software. For the most part, software of this type will primarily focus on taking over the search engine and the homepage of the browser and filling them with page redirects, pop-ups, ads, and banners. The idea is that this activity would boost the traffic of certain sites and, in turn, generate advertising revenue on the basis of the Pay-Per-Click/View models. For the most part, this doesn’t put the affected computer in any immediate danger but could undoubtedly be very frustrating, counterproductive, and also lead to more serious issues in the future, which is why it’s still best if the unwanted software gets uninstalled at the earliest opportunity.
Sibelius6 for Mac
Sibelius6 for Mac is a browser hijacker intended to get added to your browser and modify it for the purposes of online marketing. Sibelius6 for Mac will try to put a new search engine in your browser and flood your search results with advertised content.
The problem most users have with this sort of activity is that the unwelcome ads and the changes in the browser make surfing the Internet quite more difficult and significantly less efficient. However, this is neither the only nor the biggest problem related to the presence of a browser hijacker in one’s computer. What’s an even greater issue is the potential threats that may be hidden behind the ads and the redirects launched by the hijacker. If you don’t make sure to avoid them, the end result could be the exposure of your computer to significantly more harmful forms of software, including threats like phishing malware, ransomware, Trojan horses, and so on.
The Sibelius 6 Malware
The Sibelius 6 malware is a small software component that gets installed in the browsers of Mac systems and introduces unwelcome changes in their settings. The Sibelius 6 malware is intended to collect data from the browser and then use said data for the display of targeted advertising content.
In most cases, a browser hijacker like Search Marquis or Search Baron won’t give the user the option to choose what data is collected. Furthermore, users are oftentimes not even informed about the collection of data from their browser.
The Sibelius 6 Virus
The Sibelius6 virus is an ad-displaying tool used by online marketers to earn money from Pay-Per-Click and Pay-Per-View ads and page-redirects. If the Sibelius6 virus is allowed to operate in the computer for long, exposure to ransomware, Trojans, or other more serious threats becomes possible.
Again, the main problem here is that the content these hijackers tend to advertise may not always have reliable and trusted origins, which is why uninstalling and fully removing the unwelcome app is always the safest solution. Detailed instructions on how you can do this on your own will be provided in the removal guide at down below:

Remove Sibelius6 Virus from Mac
The steps described below offer you a quick alternative way to remove Sibelius6 from your Mac browser:
- Start by navigating to your Mac browser and opening it.
- Next, select the “Preferences” menu and tap on “Extensions”.
- This will open a list of all the extensions that have been installed in your web browser.
- Go through the entire list carefully and search for any unfamiliar extensions and entries, especially for Sibelius6.
- If you detect Sibelius6 or anything unfamiliar or suspicious, remove it from your Mac. The quickest way to do this is to click on the trash bin icon.
In case this does not resolve your issue with Sibelius6, then you need to proceed to the more detailed instructions on how to get rid of Sibelius6 in the removal guide that follows.
The removal process of Sibelius6 begins with quitting your Safari browser if it is working. In case you have difficulties with that, or the intrusive app is preventing you from doing so, then you may need to Force Quit Safari by going to the Apple menu and taping on Force Quit.
Another alternative way to do that is to simultaneously press ⌘, Option, and Escape keys from your keyboard. Once you do this, a dialog box named Force Quit Applications will appear on your screen. Select the Safari browser from this dialog box and click the Force Quit option. Confirm the action by clicking the “Yes” button at the dialog window that pops up.
WARNING! READ CAREFULLY BEFORE PROCEEDING!
Through your Finder app, locate Applications and then proceed to the following directory: 
This will start the Activity Monitor that will show you a list of processes. Carefully look at all of them and, if you think that there is a process that is linked to Sibelius6, seems unfamiliar to you, or is using higher than normal memory and CPU, highlight this process with your mouse. After that, click the “i” button at the top to open up the following box in your screen:
Then, click on the Sample button at the bottom of the window. A new dialog box that looks like this will open:
Save the sample file of the process in question. Do the same for any other process you believe could be part of the threat, or seems questionable. Then, upload the saved files in our free online virus scanner. If any of them gets flagged as a threat, go to the Activity Monitor, locate the flagged process and select the “Quit Process” option. If a prompt dialog opens, confirm the action by clicking on Quit. After that, delete the sample file as well.
In the third step, you need to launch Safari again but without relaunching any previously opened tabs and pages. To do that, hold down the Shift key on your keyboard while opening Safari. Once Safari is launched, release the Shift key.
In the event that Sibelius6 still manages to open some unwanted pages, then Force Quit Safari again just as described above and switch off your Internet.
If you are using Wi-Fi, select Wi-Fi off in you Mac’s Menu to turn it off. If you are using a cable internet (Ethernet connection), unplug the Ethernet cable from your computer.
Once the Internet connection is off, relaunch Safari safely by pressing and holding the Shift button to prevent previous pages from opening. Next, go to the Safari menu and select “Preferences” as shown on the image below.
Then, go once again to the Extensions tab to check if Sibelius6 hasn’t reinstalled some of its extensions in the browser.
If you detect any extensions that you don’t recognize or seem to be related to Sibelius6, remove them by selecting the Uninstall button. In case you want to be perfectly sure that there aren’t any unwanted extensions that are messing with your Safari browser, you can safely uninstall all of them. There are no extensions that are critically required for the normal operation of your system and your Safari.
Once you are done with the instructions in step 4, you will need to remove all website data from your affected browser.
- From the Safari Menu, select Preferences but this time tap on Privacy as show on the image below:
- Next, select Remove All Website Data and confirm the action by tapping on Remove Now. Note!!! By doing this all stored website data will be removed, including your saved login credentials and passwords. Thus, after you remove all website data, you will have to know your login details to sign-in again for all websites that require authentication.
- From the same Preferences menu, select the General tab this time.
- A dialog will open where you can check if your Homepage has been hijacked. If it is linking to some unwanted or unfamiliar URL, change it to the address you want.
- After you are done with the above, go to the History menu and navigate to Clear History. Select a browsing history period that covers the time before Sibelius6 was detected on your computer and tap the Clear Browsing History button. This will prevent you from accidentally opening any of the unwanted web pages again.
Note: Keep in mind that Sibelius6 has most likely infected all the browsers in your system. Thus, the instructions described above need to be applied for all browsers you are currently using in your Mac.
