How to Remove Mac Clean Plus from MacOS


Mac Clean Plus

Generally speaking, if you own a Mac, then you are probably not going to need any type of system optimization software since Apple computers have that covered by default. The truth is that most antivirus, anti-malware and system optimization tools for Mac are not as helpful or as beneficial as their developers claim they are. Today, our current article will be focused on one particular tool for Apple computers that seems to be causing more issues than it actually solves. It is a PUP (potentially unwanted program) known under the name of Mac Clean Plus and here you will learn why it might not be the most desirable piece of software. We also have a guide that will help you uninstall the program if removing it is what you want to do.

Why is it potentially unwanted?

The most common issue with optimization software for Mac is that most of them, as we already mentioned, are not all that helpful and might actually cause certain issues. Some of those programs might for example double as Browser Hijackers or Adware and be used to feed your browser with adverts or mess with its settings for the sake of online marketing. Others could potentially interfere with the normal functioning of your system and some might simply be incompatible with Mac computers (though they might be advertised as being otherwise). Those potential problems with such optimization tools are not only annoying and frustrating but they could also make your machine’s performance worse or expose it to actual software threats. For example, if some PUP tends to flood your browser with adverts, banners, pop-ups and box messages, there’s always the chance that some of them might not be safe and might actually redirect you to websites with hazardous contents upon clicking on them. All in all, it is hardly ever worth putting up with such a program, especially since most of them do not really have much, if anything, to offer. Of course, this does not mean that all such programs are complete bloatware, yet a healthy dose of skepticism towards Mac optimization software might turn out to be quite beneficial.

Can it be harmful?

There are many users that panic as soon as something strange starts happening with their computer thinking that it is some sort of a malicious Trojan Horse or Ransomware virus. First of all, if you are using Mac, then the chances of you getting a malware infection on it are rather slim. In addition to that, keep in mind that even if a certain program like Mac Clean Plus appears to be doing something unwanted, there’s probably no reason to worry since PUP’s, though irritating and undesirable, are not actual viruses. Keep in mind that unlike actual software threats like the ones we mentioned above, tools like Mac Clean Plus are legal programs and regardless of how useful and helpful they actually are, they are in no way forbidden by the law. Obviously, with actual malware/viruses like Trojans, Ransomware, Spyware, etc. it is the exact opposite.

How did the program get inside your system?

Some users willingly install software the lies of Mac Clean Plus in an attempt to either boost their Mac’s performance or make it safer. However, many people tend to have the program installed onto their computers without their knowledge or agreement. There are quite a few methods through which this can happen but the most common one is through software bundles. If you have the PUP on your machine and you do not know where it came from, then you have most likely installed some other piece of software onto your PC that has had the Mac Clean Plus bundled with it. That is why users should always be careful with what they install and what download sources they use.

Other things you must be on the lookout for are shady online offers and ads as well as suspicious e-mail letters. Though Mac Clean Plus is likely not getting distributed via such means, other potentially unwanted programs might be. That is why we highly recommend that you do indeed avoid websites that seem to generate a lot of obscure and sketchy banners, box messages and pop-ups since those might not be safe. Additionally, it is important to always re-consider opening an e-mail message if it looks suspicious. Keep in mind that junkmail is currently one of the top most common techniques for spreading all sorts of undesirable software and even though most e-mail providers have an integrated spam filter, there’s always the possibility that a spam letter might make it through.
