Potentially Unwanted Programs: It's Not Always Malware | Huntress

Potentially Unwanted Programs (PUPs) are applications that users often install inadvertently while downloading free software, manifesting as intrusive ads, pop-ups, and generically named applications. Unlike malware, PUPs operate in a gray area between legitimate and malicious software, typically bundled with other downloads rather than explicitly designed to cause harm. Security teams need to distinguish PUPs from true malware to properly allocate resources and set appropriate remediation priorities.

Why it matters: Security practitioners should understand PUP behavior and prevalence because they consume incident response capacity, generate user complaints, and can obscure detection of genuine threats, requiring clear classification policies to manage effectively.
