Why is Prupdater regarded as a PUP?

We already mentioned the main concerns that most cyber security experts have with this app, namely, the way it tends to get installed onto user’s machines and the questionable functionality that it may have.

Firstly, we will cover the installation of Prupdater and why it might be seen as a potential issue. Normally, most regular programs get installed after the user willingly downloads their installation file from their official site or from a third party site used to distribute them and then run the installer to install the program. However, in the case of PUPs like Prupdater, things oftentimes do not go that way. In fact, most potentially unwanted pieces of software tend to get installed without the user’s knowledge by employing something called program-bundling. This is a method for software distribution where the an application is added to an installation package where there is one main program and one or more added components, the installation of which is optional. Prupdater is oftentimes added as such an optional component to the setup wizards of other programs. However, the issue is that most of the time the optional components are enabled by default if the customer goes for the Quick installation configuration. In order to override that, one would have to go out of their way and access the Custom menu where they’d be able to uncheck anything optional they’d prefer to leave out.

Type Regedit in the windows search field and press Enter.

Inside, press CTRL and F together and type the threat’s Name. Right click and delete any entries you find with a similar name. If they don’t show up this way, go manually to these directories and delete/uninstall them:

  • HKEY_CURRENT_USER—-Software—–Random Directory. It could be any one of them – ask us if you can’t discern which ones are malicious.
    HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random
    HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—- Random

Of course, most users do not do that and simply rush through the setup menu clicking Next without paying any attention to the details of the installer which is how many customers end up getting unwanted software on their computers without even knowing how it has happened. This, however, isn’t the only issue with the installation of Prupdater. Aside from using this rather sneaky tactic for getting onto as many computers as possible, this app has also been reported to get distributed alongside other sketchy apps and programs like Adware, Browser Hijackers and other similar pieces of unwanted software. If you have read any of our other articles about Browser Hijackers and Adware, you’d know that these are forms of software that you’d certainly not want to have on your machine. All things considered, the very installation of Prupdater is a big red flag that should be enough for most users to make sure to avoid this program and remove it from their machines if it has already made its way there.

Functionality?

According to its developers, Prupdater is supposed to detect outdated software on the user’s PC and automatically update it for them. The problem here is that, according to a number of researches, this app oftentimes gives false positives after scanning the PC for outdated programs and later prompts the user to install some update that isn’t really what it seems. That way, if you aren’t careful and agree to install everything that the PUP tells you to, you might end up getting even more unwanted software on your machine and in some cases, you might even get your PC exposed to some serious cyber threats like Spyware, Ransomware or Trojan Horses. On its own, the potentially unwanted program from this article isn’t really something that could directly threaten your computer but due to its questionable practices, it is likely better to simply get rid of it and also uninstall any other programs that might have gotten in your system alongside it.
