Mac File Opener PUP – Distribution
The Mac File Opener 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 File Opener 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 File Opener. 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 File Opener, and download it.
This is how the website looks like:
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 File Opener PUP – Information
Mac File Opener 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 File Opener remains a questionable software as it is also known to show such advertising pop-up messages.
Interestingly enough, the alert notifications and pop-up messages are not the only thing that the Mac File Opener software is designed to do. The Info.plist file inside the application reveals a list of over 200 various file types that it claims to be able to open. If you try to open a file which doesn’t have a corresponding application associated to it, the file will be opened by Mac File Opener.
Afterward, Mac File Opener 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 File Opener website, owned by PCVARK, which tries to install Mac Adware Remover or similar applications to Mac Space Reviver. 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 scare message reads the following:
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.
As you can see from the above image, the PCVARK company also collects various information from you, without your explicit consent.
