Why You Should Avoid Freeware Apps

One of the primary ways PUP.Optional.BundleInstaller is distributed is through bundled software installations. Freeware applications, although useful, often come with hidden costs: additional, unwanted software. Here’s why you should be cautious when downloading and installing freeware:

• Bundling: Developers of free programs bundle additional software (like PUP.Optional.BundleInstaller) into the installer. You might think you’re only installing the main software, but you’re also agreeing to the installation of unwanted programs.
• Monetization: These bundled programs often serve as a way for third-party developers to make money. For example, they may change your homepage or install adware to generate clicks or views.
• Disguised Features: Often, these bundled programs are disguised as useful tools or features. In reality, they are only there to disrupt your browsing experience and collect your personal data.

To avoid this, always choose the custom installation option when downloading software and carefully read through the prompts to decline any unwanted programs.
