Browser hijackers are a specific category of software that is generally regarded as undesirable or unwanted. Applications that belong to this software family are well-known for their obstructive capabilities especially when it comes to affecting the user’s regular browsing activities. Most hijackers are capable of changing the search engine or the homepage (or new-tab) page of the user’s main browser as well as causing the appearance of various forms of intrusive advertising content. Additionally, some hijackers are also known for causing sudden and unpleasant redirects to different sites that the pesky software is seeking to promote. One other thing to mention here is that the majority of hijacker applications can affect any browser on your system – Safari,Chrome, Firefox, Opera, Edge or any other. It really doesn’t matter what browsing program you are using as hijackers are typically developed to be compatible with all of them. In the lines below, you can learn more about one recently released hijacker version, a page-redirecting software that goes under the name of Schooldozer. If you need help removing this irritating and potentially unwanted application from your computer in case it has already been installed there, you can also find detailed removal instructions on this page – a guide down below will give you all the information and steps that you might need in order to quickly and effectively uninstall the hijacker. To further help you and ease-up the removal process, we have also added a suggested malware-removal tool inside this page that you can download and use in combination with the guide for even better removal results.

Hijackers are used for advertising

Online ads are everywhere as you all well know. However, one can easily avoid most of them if they get an ad-blocker. However, the advertising materials coming from hijacker applications are different than site-generated ads. In case you have a hijacker, even an ad-blocker won’t make your browsing program immune to the various advertising content that is going to get displayed on your screen once you start using your browser. Not only that, but as we already mentioned, page-redirects like Schooldozer can also alter some of your browser’s settings as well as suddenly open new sites that you never really meant to visit. All of this, of course, is done for the purpose of generating income through Internet marketing. As the number of users subjected to the advertising campaigns conducted by Schooldozer increases, so does the overall amount of income that the creators of the hijacker gain from their product.

Schooldozer Removal 

Step1

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:

chromesample

Do this for all processes you believe are part of the threat, and run any suspicious files in our online virus scanner, then delete the malicious files:

Step3

The next step is to safely launch Safari again. Press and hold the Shift key while relaunching Safari. This will prevent Safari’s previously opened pages from loading again. Once Safari is opened up, you can release the Shift key.

On the off chance that you are still having trouble with scripts interrupting the closing of unwanted pages in Safari, you may need to take some additional measures.

First, Force Quit Safari again.

Now if you are using a Wi-Fi connection turn it off by selecting Wi-Fi off in you Mac’s Menu. If you are using a cable internet (Ethernet connection), disconnect the Ethernet cable.

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,

Preferences in Safari

and then again on the Extensions tab,

Select and Uninstall any extensions that you don’t recognize by clicking on the Uninstall button. If you are not sure and don’t want to take any risks you can safely uninstall all extensions, none are required for normal system operation.
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.

Still in the Preferences menu, hit the General tab

General Tab in Safari

Check if your Homepage is the one you have selected, if not change it to whatever you prefer.
Default Home Page

Select the History menu this time, and click on Clear History. This way you will prevent accidentally opening a problematic web page again.

The object of advertising could be anything – online services, software products, Internet stores, different sites, you name it. In some cases, the users might actually get offers that are relevant to their interests as many hijackers actually tend to scan the user’s browser and gather telemetry data for the purposes of targeted marketing. However, most of the time a hijacker such as Schooldozer would be seen as nothing more than a useless annoyance that needs to be gotten rid of. Hijackers rarely provide the end user with any real functionality that the customer might consider helpful which is why we believe that it is simply better if you get rid of Schooldozer ASAP.

Further advice regarding browser hijackers

It is important to understand that, although such applications aren’t malicious viruses like Trojans and Ransomware, they could still cause problems and potentially expose your PC to danger (though indirectly). Therefore, we highly recommend you abstain from opening any ads and pop-up suggestions that come from such page-redirecting software – you can never know if the offer is real or if it is actually a misleading link to some sketchy site that might be compromised and used for distribution of malware. Generally speaking, if you currently have Schooldozer on your computer, removing it is the most sensible course of action that you can take otherwise the risk of landing some nasty infections like Spyware, Trojans, Ransomware and Worms would likely increase.

As far as avoiding such applications in future, it is necessary to understand how they are normally distributed. Most hijackers find their way to people’s computers through various methods. Some of those methods getting distributed through spam e-mails or via malvertising. Some hijackers get added to other programs as bundled software. In such a case, installing the main program using the default setup configuration would also likely install the hijacker as well. Therefore, do not forget to use the Custom/Advanced setup options when you are about to install anything on your computer, especially if it is some form of freeware. Using such an expanded installation option would hopefully give you more control over what gets installed and what is left behind. If you see bundled apps that are likely to be unwanted, opt-out of their installation before you continue so that no hijackers make it inside your machine.
