UpdateAgent Mac


UpdateAgent is a type of program that infiltrates the main browsers on macOS computers. UpdateAgent does this for the purpose of converting these browsers into platforms for online advertising.

And usually, this is achieved by installing ad-generating components in the browsing program in question. Hence, users who’ve been affected by this type of software begin to notice vast increases in the quantity of banners, popups, in-text links and other types of online advertising materials while they’re browsing the web.

In addition, software like UpdateAgent, Navlibx, QSearch may alter some of the browser’s configurations, whether you’re using Chrome, Safari, Firefox or some other web browser. And these are usually pertaining to the default search engine, as well as the homepage URL. Therefore, you are likely to experience changes there, as well. Last but not least, your browsing program may begin to cause page redirects that automatically take you to various sponsored web locations, which can certainly be very annoying, too.

So, if you would rather not have to put up with your browser rebelling against you, you will have to remove UpdateAgent from your computer. And as this type of software tends to try and make this process difficult for users, you may benefit from a manual removal guide such as the one we’ve put together below.

UpdateAgent for Mac

UpdateAgent for Mac is a browser hijacker that takes charge of the main browsing program on your computer. UpdateAgent for Mac is not harmful, but most experts identify it as a potentially unwanted program or PUP.

This is due to several facts all at once. For one, as you’re no doubt already well aware of, UpdateAgent doesn’t exactly openly request your permission to be installed on your machine. Usually this happens in a sneaky and underhanded way, because no one in their right mind will want to have such software installed on their computer. In this case, UpdateAgent was likely included in the setup of some other application as an optional install. And if you weren’t paying too much attention to the setup, you likely missed the step where you could have left the browser hijacker out of the installation process.

What is UpdateAgent?

Another reason why UpdateAgent is seen as unwanted is that it may expose your system to viruses. UpdateAgent acts as a middle man between you and obscene amounts of content, and some of it may prove to be unsafe.

It may so happen, for example, that a spontaneous page redirect takes you to some infected website. Or you might click on an ad that is linked to some insecure web location. And as a result, your system may be attacked by ransomware, Trojan horse viruses and various other types of malicious code.

The UpdateAgent app

The UpdateAgent app is not a malicious piece of software, contrary to common belief. Nevertheless, the UpdateAgent app may have various negative consequences on your system, such as sluggishness and slowdowns.

Therefore, in order to avoid such things from happening to your Mac, it’s best to simply have the hijacker removed altogether.
