Users Often Install Browser Hijackers and PUPs (Potentially Unwanted Programs) Unintentionally

PUPs use a variety of tactics to get installed on users' systems without their knowledge or consent. One common tactic is called software bundling, where the PUP is included as an optional component in a legitimate software package. During the installation process, users may be presented with a list of additional software that they can choose to install or decline. However, PUPs are often pre-selected for installation, and users may overlook or miss the option to decline them.

Another tactic used by PUPs is misleading advertising or social engineering techniques that trick users into downloading and installing the software. For example, PUPs may be promoted as useful or legitimate tools, such as system optimizers or antivirus software, through fake pop-up ads or spam emails. Once installed, however, the PUP may not perform as advertised and may even compromise user privacy by tracking their online activity or displaying intrusive ads. PUPs may also disguise themselves as legitimate software updates or security patches, prompting users to install them to ensure the safety of their system.
