Potentially Unwanted Programs (PUPs) are programs that, although not harmful, can negatively impact the user experience by displaying unwanted advertisements, slowing down system performance, or even tracking user behavior without explicit consent. These applications often come bundled with legitimate software or masquerade as valuable tools, making it challenging for users to avoid them.

In a recent analysis of intrusive and untrustworthy applications, infosec researchers identified a program named ProtocolView. Upon closer examination, experts classified ProtocolView as adware, specifically targeting Mac users. This application is designed to generate revenue through advertisements, which can interrupt user activities and degrade overall system performance. Furthermore, ProtocolView is part of the notorious AdLoad malware group, known for its deceptive distribution methods and persistence mechanisms. By embedding itself into users' systems, ProtocolView exemplifies the typical behavior of PUPs, where the primary objective is to exploit the user for profit while masquerading as a harmless or even beneficial tool.

ProtocolView May Expose Users to Unnecessary Privacy and Security Issues

Adware is programmed to generate revenue for its developers by displaying advertisements across various interfaces, including visited Web pages and desktops. These advertisements can promote a range of dubious content, including online scams, unreliable or unsafe software and malware. When users click on these advertisements, they may trigger scripts that initiate stealthy downloads or installations, potentially compromising the security of the device.

Any genuine content encountered through these advertisements will be likely endorsed by fraudsters who exploit affiliate programs to earn illegitimate commissions. Additionally, adware often possesses data-tracking capabilities, which is likely the case with ProtocolView. The information collected can include visited URLs, viewed pages, search queries, browser cookies, account login credentials, personally identifiable details and credit card numbers. This sensitive data can then be purchased by third parties, which may further compromise user privacy and security.

How to Avoid Allowing PUPs and Adware onto Your Devices?

To avoid allowing PUPs and adware onto your devices, users should follow several best practices:

  • Be Cautious with Downloads: Only download software from reputable sources. Avoid using third-party websites or unauthorized app stores, as these can often host PUPs and adware. Always prefer official websites or trusted platforms like the Apple App Store or Google Play Store.
  • Read Installation Prompts Carefully: During software installation, take the time to read each prompt carefully. Avoid the default or express installation options, as these can sometimes include additional unwanted programs. Instead, choose the custom or advanced installation options to uncheck any extra software that you do not wish to install.
  • Use Anti-Malware Software: Install reputable anti-malware programs to detect and block PUPs and adware. These security tools can provide real-time protection and regularly scan your device for potential threats.
  • Keep Any Software Updated: Regularly update the operating system and all installed software programs. Updates often include fixes for vulnerabilities and exploits.
  • Be Wary of Free Software: Free software often comes bundled with PUPs as a way for developers to generate revenue. If you must use free software, make sure it comes from a trusted source and pay close attention to the installation process.
  • Read Reviews and Research: Before downloading and installing new software, read reviews and do some research to ensure it's legitimate and free from PUPs and adware. User expert opinions and reviews can provide insights into any hidden issues.
  • Use Browser Extensions Carefully: Be cautious when installing browser extensions. Only install extensions from reputable developers and regularly review the extensions you have installed to ensure none have been added without your knowledge.
  • Regularly Review Installed Programs: Periodically check the list of installed programs on your device. Uninstall any software that you do not recognize or no longer need, as these could potentially be PUPs.

By following these practices, users can significantly reduce the risk of PUPs and adware compromising their devices and personal information.
