PUP.Abundler: An In-Depth Guide

Potentially Unwanted Programs (PUPs) represent a broad category of software that, while not explicitly malicious, can compromise the performance and security of a computer system. Unlike viruses or ransomware, PUPs are often bundled with legitimate software and are designed to avoid detection by standard security measures. They can cause a range of issues, from unwanted advertisements and browser redirections to significant slowdowns and privacy concerns. The term “Potentially Unwanted” reflects their dubious nature—while they may not be outright harmful, their presence is usually undesirable and can lead to a degraded user experience.
