This page aims to help you remove Mac Tweak Pro “Virus”. Our removal instructions work for Safari, Chrome and Firefox, as well as every version of Mac OSX.

Your frustration is understandable if a browser hijacker such as Mac Tweak Pro “Virus” has found its way inside your browsing program. Normally, it doesn’t really matter what your browser of choice is – the browser hijacker apps are typically created to be compatible with as many different browsing programs as possible. Naturally, the browser that get most frequently targeted by browser hijackers are ones that are highly popular and widespread, ones like Safari,Chrome,Firefox, Opera and so on. Also, it’s important to mention that switching to another browsing program is likely not going to do the trick – the hijacker will probably get to it as well and will once again try to tinker with the default homepage address, the search engine of the browser or its toolbar while simultaneously causing irritating page-redirects and generation of obstructive adverts, pop-ups, pop-unders, banners and other similar promotional content. All of this is, of course, supposed to earn revenue for whoever has created the hijacker. The online ads are a very potent tool for accumulating income and everybody wants to have a piece of the pie. The browser hijacker apps like Mac Tweak Pro “Virus” are simply software tools specifically designed and programmed to make money from the ads that they generate. The changes in the browser that you may experience are also made with the purpose of making the whole advertising campaign go smoother and be more effective. And, needless to say, there is pretty much nothing beneficial for the end user in this case. The good news is that the app you are struggling with isn’t some Ransomware, Trojan Horse or Spyware infection and will probably not cause harm to anything that’s on your computer. That being said, the removal of the hijacker is still the advisable course of action and the next instructions will help you uninstall the nagging software without the need to take your machine to a specialist.

Browser hijackers are not to be trusted

Although the representatives of the browser hijacker software family are usually not regarded as illegal or malicious pieces of software, you should know that they really aren’t apps that you’d like to allow inside your computer. The fact that apps like Mac Tweak Pro are not forbidden by the law is oftentimes a technicality. The creators of such software have managed to find loopholes in the law that allow them to make unauthorized changes to the users’ browser and swarm their screens with ads while at the same being way more difficult to remove when compared to regular programs. Also, the control over the advertisements that get shown on your screen is oftentimes very weak or outright non-existent. This means that within the stream of offers, banners and pop-ups you may also get shady and obscure advertising content that may be linked to all kinds of questionable web locations and maybe even to phishing pages, illegal sites or sites used for spreading different malware threats – Ransomware, Trojan Horses, Rootkits, Spyware and many more.

Remove Mac Tweak Pro “Virus”

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,

and then again on the Extensions tab,

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
