PUA InstallCore

PUA InstallCore is a potentially unwanted application that can fill the screen of any browser with dozens of aggressive ads, pop-ups, banners and intrusive page-redirects every time you start a new browsing session. The most probable source of these adverts is an adware application PUA InstallCore.

The Internet is full of those applications (Prozipper) and new ones get made every day with the purpose of promoting certain products, services and websites directly on the users’ screen during their web browsing. That’s why, on this page, we will focus on one of the latest representatives of this software category, an app called PUA InstallCore. Recently, many web users have reported that ads generated by PUA InstallCore have been popping up all over the screen and have been prompting them to click on various offers, redirect links and promotions. Some of them have reached our “How to remove” team with a request to help them remove these ads and uninstall their source which is why we have created the removal guide below.

The Installcore Malware

The Installcore malware, is not among the nastiest computer viruses and have nothing in common with the malicious infections that we often talk about on our website. However, despite lacking the harmfulness of a Trojan Horse or a Ransomware, adware tends to be quite irritating and obstructive once it latches onto popular browsers like Chrome, Firefox, Explorer or Safari and start spamming the screen with hundreds of sponsored ads.

For this reason, many people refer to this software as potentially unwanted and seek methods to uninstall it from the system. Such applications can constantly deliver third-party ads, pop-ups, banners and offers and cover the pages that you visit with them so as to make you click on some of the messages. The purpose of all this is, of course, financial profit for the adware creators that gets generated through the pay-per-click model. Obviously, this can lead to browsing disturbance, unwanted interruptions and general irritation for the end users. The instructions included in the removal guide down below, however, can effectively help you eliminate the PUA InstallCore and forget about its disturbance once and for all.


PUA.Installcore is not software that can directly threaten the safety of your computer. The same cannot be said about the ads that it can generate, though. The reason is the creators of the PUA.Installcore adware rarely impose any direct control over the sponsored messages that their application displays.

Most of the offers, pop-ups and promotional links are generated on a random basis, which means that nobody checks their origin and legitimacy and while you may find some intriguing and good offers, there is also a high chance of accidentally clicking on something misleading or hazardous. It is, therefore, a good idea to limit your interaction with the content that PUA InstallCore displays and try to stick to reputed sites, well-known sales platforms and trusted sellers. Otherwise, you may unknowingly put your computer at risk or get attacked by a real malware such as a Ransomware, a Trojan Horse or some other nasty virus, especially if you happen to get redirected to unfamiliar web locations.
