Mac Tweak PUP – Distribution Methods

The Mac Tweak unwanted application is being effectively distributed via freeware installers and bundled packages. You can get your Mac affected by it without even being aware, that the Mac Tweak has installed on your machine with a freeware installation or bundled package. In such packages, additional components for installation are not always disclosed properly (or at all), and you can get tricked into installing apps such as Mac Tweak. Sometimes this can be avoided if you check the Advanced or Custom option in an installation setup to see the full contents of what you are getting.

Suspicious sites are another source for the distribution of PUPs. Visiting such sites can end you up with a rogue program installed on your Mac. For instance, if you manually go to the official site of Mac Tweak, and download it. There are other sites that advertise the program with pop-ups or banners that are probably their partners or belong to the same cloth of people that spread similar software.

Mac Tweak PUP – In-depth Information

Mac Tweak is a potentially unwanted program (PUP), and it is developed by the company PCVARK. The company is known to have many applications which are considered PUPs and also puts various advertisements in their software to point to other software they have created. Mac Tweak remains a questionable software as it is also known to show such advertising pop-up messages.

Interestingly enough, the is seen to also be spread by the

AppleCare: Your system is infected with 3 viruses alert message that you can land on different Web pages.

Except, the alert notifications and pop-up messages are not the only thing that the Mac Tweak software is designed to do. Below, in the screenshot, you can see the GUI of the program, with a screen where it shows that issues have been found on your Mac machine:

Afterward, Mac Tweak shows a reasonably convincing, but fake variant of the normal OS X dialog message box which says that no suitable app is installed.

The fake message box links to the official Mac Tweak website, owned by PCVARK, which tries to install Mac Adware Remover or similar applications to Mac Tweak. All these programs have a valid, Apple-provided developer certificate, thus macOS will install them without prompting a warning or a notification of any sort.

The following pop-up message can show up from time to time, trying to prompt you into installing rogue security software which is probably also related to the PCVARK company:

The message states the following:

Warning:
The last site you visited might have infected
your Desktop with virus
Current risk: 93%

Click on the button below to install the latest Mac
security to remove all the viruses

Your Mac would have critical errors, if you do not
remove the viruses within
[5 minute counter] Install Security Update

With a timer, this message tries to trick many Mac users, with scare tactics, into installing more junk on their machines. If you have questionable behavior on your MacOS, experience slow-downs or have applications installed that you do not know where they cropped up from, consider scanning your Mac with a legitimate security software and see if you can eliminate the cause.

Be careful what data you provide, what terms you agree to, what consensus you give to people (over the phone or not) claiming to be working behind this unwanted software. Do not install secondary programs advertised from a program that claims that your Mac has issues, albeit it cannot fix them alone.
