Pua:Win32/Presenoker is a potentially unwanted application (PUA) that is often identified and flagged by Microsoft Windows Defender and other antivirus software. It’s not a virus in the traditional sense, but it can be harmful or intrusive.
This PUA often comes bundled with other software during installation. It may also be downloaded from untrustworthy websites or through spam emails. Once on the system, it may display unwanted ads, change browser settings, redirect searches to advertising or phishing websites, or slow down the system. It can also potentially collect sensitive personal data.
Users often unknowingly download Pua:Win32/Presenoker when they do not carefully read and opt out of additional “offers” during the software installation process. Therefore, it’s crucial to download software from trustworthy sources and to pay attention during the installation process, unchecking any boxes related to additional downloads or changes to the system.
