Intrusive Actions of PUPs (Potentially Unwanted Programs) Like the App Browser Extension

The presence of a Potentially Unwanted Program (PUP) on your computer could create many issues. From invasive advertisements promoting tactics or dubious software products to the intentional tracking and monitoring of online activity, PUPs have the capacity to cause serious consequences for computer users. To properly protect yourself against the risks posed by these programs, you need to understand what actions a PUP typically takes.

A typical action exhibited by many PUPs is making alterations to settings and configurations associated with an operating system or commonly used Web browsers like Chrome, Mozilla Firefox, Explorer, Safari, etc. These alterations can include changes such as modifying the homepage for your browser, automatically changing the search engine you use and adding toolbars or extensions you never approved.

Many PUPs are designed specifically with the display of advertisements as a core part of their business model. Therefore, one of the most common ways users identify a PUP is when they start seeing various pop-up windows or advertisements displayed while they are browsing websites or using applications. While some of these may be entirely harmless in terms of redirecting traffic from one website to another, regularly displaying advertisements can negatively impact people's experience on their computers or connected devices.

PUPs can Monitor Users’ Data

Another typical action taken by many PUPs involves constantly tracking users' online activities—including which websites they visit most often and what searches they perform. This information is then typically sold off or used by advertisers in their efforts to better target particular consumers or groups with advertisements tailored directly to them based on their interests or behaviors online. Additionally, the collected activity data could make users vulnerable to exploitation by con artists who will abuse the harvested personal details.
