Global PC Cleaner Pro is a potentially unwanted program (PUP) that is often categorized as a rogue system optimization tool. This software purports to enhance your computer’s performance by eliminating unnecessary files, fixing registry errors, and boosting speed. However, its real intention is far from beneficial. Rather than improving system performance, Global PC Cleaner Pro often results in system slowdowns and intrusive advertising. This program employs scare tactics, displaying exaggerated scan results and false positives to convince users that their computer has severe performance or security issues, thereby prompting them to purchase the full version of the program. The infection process of Global PC Cleaner Pro is quite subtle. It primarily spreads via bundling, a deceptive software distribution technique. Bundling entails packing several programs into a single software package, allowing the unwanted program to be installed alongside the desired software unknowingly. When users install software from freemium sites or choose the “Recommended” or “Quick” installation settings, they inadvertently consent to installing additional programs like Global PC Cleaner Pro. Once installed, this rogue software initiates system scans automatically and presents the user with alarming results, pushing for the purchase of its premium version. It is important to remember that such programs are designed to exploit users’ fears about their computer’s health, and their claims are rarely accurate. Always ensure to download software from official sources and choose the “Custom” or “Advanced” installation to avoid such unwanted programs.
