What is Mega Backup (and how to delete it)

In the following article, we will be focusing on a program known under the name of Mega Backup. There have been quite a few complaints about this particular piece of software and we are here to explain what it actually is, whether it can cause any damage to your PC and how you can remove it (should you decide to do so).


Mega Backup is a legal and legit program that enables its users to backup their personal files to a cloud supported by the developers of the application. The program is available for both Windows and Mac. Obviously, nowadays having a backup of your valuable data files is a must. There are a lot of viruses out there such as Trojans and Ransomware that can go directly for your personal files and if you do not have a backup of them, you might  lose the data forever or have to pay ransom if you want to get it back. However, not all backup services are the same and in the current case, even though Mega Backup is legit and adequate, it still possesses certain rather unpleasant traits that we will be focusing on in the next few paragraphs. In the current article, we will be referring to the Mac version of the software in question.

The issue

Users, who have directly installed the full (paid) product, probably do not experience any problem with the program in question. However, if you only want the free version, things are going to look differently. This is where Mega Backup starts to nag the user with various adverts, banners and box messages, so as to persuade them to get the paid version of the program. This can obviously be quite frustrating and annoying, which is also the reason why many people regard Mega Backup as unwanted software. Of course, the ones who have had already paid for the full product are not subjected to the intrusive ads and pop-ups, but for everyone else – the ads are going to be there and they are not going to go away unless the program is either uninstalled or upgraded.

How unwanted?

As we mentioned above, many people who have faced the invasive advertising materials of Mega Backup tend to think of the programs as some form of malware. This is obviously a misconception. The application itself is actually adequate in its field and when the paid version is obtained, the user is with several neat options such as having automatic backup updates each day and being able to remotely access your backed-up data from different devices. However, if you are only using the free product, there will be big limitations to the functionality of the program with the added bonus of being constantly annoyed by the somewhat aggressive advertising techniques of Mega Backup. All in all, it is up to the individual user to decide whether it is worth keeping this program on their PC the way it is, upgrading it and getting all the benefits from the full version or uninstalling it and seeking another provider of backup services. For those of you, who have decided to go with the third option, we have prepared a guide that will help you uninstall the software from your Mac and fully remove anything that it might have left out. Do note that even though the program is legit, sometimes the removal process might be a bit more elaborate than it would be with most other programs (hence, the need for a guide).

Preventing the installation of other potentially unwanted programs

Even though many people willingly install Mega Backup, sometimes the program can get installed onto somebody’s PC without the user necessarily knowing about it. This most commonly happens via the so-called file-bundling software distribution method. This is when a piece of software is bundled with another program and when that other program is installed, the bundled software gets installed as well. Oftentimes such bundled applications are programs that the user would not actually want to have. This is why it is important to always pay attention to what you are about to install. You should always carefully look through the setup wizards of new software you’re about to install and if you see there that there are any added programs, look them up and determine whether, you’d be okay with having them on your PC. If you think that you’d be better off without the added applications, uncheck them before installing the main piece of software and that way you will keep your Mac clean and free of any potentially unwanted programs.
