Danger level 3
Type: Potentially Unwanted Application


Macbright is classified as a potentially unwanted program that has the functionality of advertising-supported software (adware) as well. Once this PUP slithers in – and it was found that it can only affect Mac operating systems – it should start showcasing various third-party advertisements. At first, you might not notice this at all; especially if the ads are shown in an inconspicuous manner. However, once you notice them, you are likely to be irritated by them. As you might know already, interacting with ads showcased by unfamiliar software can be extremely dangerous. If you interact with ads thinking that they belong to the sites they show up on, you might get into trouble. Hopefully, that does not happen, but we need to consider all outcomes, and one of them is that you jeopardize your virtual security by interacting with malicious ads. Needless to say, it is strongly recommended that you remove Macbright from your operating system, and you can learn all about that via this report.

According to recent research, Macbright works on the OSX environment only. The PUP is not introduced in an official manner, and it does not have an official installer. Due to this, it is likely to rely on third-party installers to spread. Even if you install programs from seemingly legitimate sources, you need to be cautious about the installation setups. If you have the option to choose custom installation, use it to make sure that unwanted programs do not slither in without your notice. Needless to say, this is a particularly important step if you are using unfamiliar installers offered via potentially unreliable sites. If you end up installing software you had no intention of letting in, it is advised that you delete it as soon as possible. Employ a legitimate malware scanner to inspect your operating system, and you will soon learn what kind of software is active on your operating system. Needless to say, if Macbright is found along with other infections, you cannot ignore them either. You MUST delete them.

Once Macbright is activated, it should communicate with advertising networks to place ads. They could be placed on the shopping sites you visit, or they could be injected into the search results. Whether you discover in-text ads, banners, pop-ups, or interstitial ads that pop up in new tabs and pages, we advise keeping away from them. If you interact with them, cookies could be placed to track information about you. Macbright itself might collect data using special tools, and that is risky. What if personal, sensitive information is recorded? What if the data-trackers enable unreliable parties to create more attractive offers that hide malicious scams or misleading offers? All of this is possible, and until the PUP’s creator reveals more information about it, we cannot dismiss the possibility of it being malicious. Even if the ads shown by this suspicious program are not malicious, they are unlikely to bring you any real and beneficial offers. They are more likely to be introduced to you so that money could be made. It is likely that a pay-per-click system is set up, and the developer of adware earns a pretty penny every time you click an ad.

If Macbright is represented via the Applications menu, it should be enough to remove the unwanted app and then reset your browsers to get rid of any adware traces. If the potentially unwanted program manages to conceal itself, you might have to employ the help of trustworthy and legitimate anti-malware software. Mac OS users should not have much trouble finding the right anti-malware tool, but we have to warn you that inadequate apps and even malicious rogues exist. Make sure you do your research and stay clear from all applications that are mysterious or that have bad reputations. Note that there are more reasons than one to employ anti-malware software. While in this situation you might be interested only in having Macbright deleted, you also need to think about other potentially existing threats, as well as the overall protection. At the end of the day, whatever you choose to do, if we can help you with it, we will try our best to assist. Use the comments section below to post your questions.
