Prime Updater also known as PrimeUp! Is a piece of software that the majority of security researchers regard as potentially unwanted due to its questionable functionality and due to the way it might get installed on your PC. On paper, this app is supposed to detect programs on your PC that need to be updated and automatically update them for you. However, reports from numerous cyber-security experts suggest that this might not be the whole story and that there are likely certain undesirable traits that this app might possess.

Here, we will go over the main characteristics and most typical traits of this app and we are going to explain to you why this program might not be something that you’d want to have on your computer. For users who already have had Prime Updater installed on their machines, we can also offer you a guide that will enable you to remove it if you closely follow the instructions in it. Remember, though, that this isn’t some nasty and dangerous piece of malware and even though at times the presence of Primer updater on your PC might seem disturbing, it is unlikely that this app would actually attempt to cause any harm to your computer. Prime Updater is a legitimate piece of software, yet, because of the way it tends to get installed onto users’ computers and because of its potential to obstruct and disrupt your work on your computer, it might simple be better to get rid of it instead of allow it to continue nagging you with its presence.

What is Prime Updater?

The first thing that we ought to tell you about this app is that it typically gets installed onto people’s machines without the knowledge of the users. Now, this doesn’t mean that the app infects the targeted computer the way that virus programs like Ransomware and Trojans can. In fact, in the majority of instances, the users themselves agree to install apps like Prime Updater, however, they typically do that without actually knowing it. How does this happen, you might ask. Well, there is a software distribution technique know as file-bundling which is the main tactic used by developers of unwanted programs, through which they are able to spread their products to more and more computers. A software bundle is an installation package for a certain program (normally, some freeware application). However, the package might also contain added components such as Prime Updater or some other unwanted app. Although in most cases it is possible to leave out the added component by accessing the Advanced setup menu and unchecking the checkbox next to the bundled app, the majority of users do not actually do that and instead use the Quick setup configuration which typically allows the installation of all bundled elements.

The fact that the presence of added apps is oftentimes not properly disclose doesn’t help either. All this leads to many users getting Prime Updater installed on their machines without even knowing it. Another problem with this particular app and the bundles it is typically distributed with is the fact that the installation packages that contain PrimeUP! oftentimes also have some other unpleasant apps in them such as Adware programs and Browser Hijackers. We have numerous articles regarding such software on our site where we thoroughly explain why they are not the kind of programs and apps you’d want to have on your machine. All in all, the Prime Updater tool really seems to use some rather questionable installation methods which is why you are advised to always opt for the Advanced setup settings when you are about to launch the installation of some new program on your computer. That way, if you see that Prime Updater is added as a bundled install, you’d be able to uncheck it as well as any other potentially unwanted app that might have been added to the installation bundle.

Questionable functionality

We cannot tell you for sure just how effective Prime Updater is and how well it delivers its promise to update outdated software on your PC. However, some reports from software safety researchers suggest that many of the results about outdated programs on the user’s PC coming from this app are actually fake and are supposed to trick the user into installing more unwanted software on their computers and not to help them update any programs. This is, in fact, a commonly employed tactic which can be seen as an aggressive form of software promotion and distribution. Regardless of how you call it, we advise you to always be on your guard for such sketchy schemes and also it’s best if you manually update your software instead of allowing some questionable third-party app to do that for you. After all, there are already more than enough red flags concerning Prime Updater which should tell you that this might not be a piece of software that you’d want to trust.
