PC optimization tools, commonly referred to as clean-up applications, aim to enhance the speed, efficiency, and overall performance of your computer. By executing a variety of maintenance tasks, these applications claim to eliminate unnecessary files and optimize system operations. In theory, this process requires specialized knowledge of the Windows operating system to implement effectively. However, caution is advised when choosing these applications, as some may inadvertently degrade your PC’s performance.
Instead of merely clearing out temporary, junk, or duplicate files, some optimizers can lead to system lag and diminished performance. Several of these applications have troubling histories that make their continued use feel counterproductive and risky.
CCleaner
The Avast-Owned PC Optimizer
CCleaner, now owned by Avast, raises immediate red flags regarding its reliability. The association with a well-known antivirus software might suggest credibility; however, Avast’s history casts doubt on the efficacy and trustworthiness of this optimization tool.
Avast has faced criticism for collecting and selling user data, leading to their inclusion on lists of questionable software practices, as noted by the Federal Trade Commission. Such concerns make it difficult to trust any products associated with the company, including CCleaner.
Additionally, the infamous 2017 supply chain attack underscores potential security vulnerabilities. As reported by WIRED, this incident allowed malware distribution to go undetected for a prolonged period, impacting millions of users. Given the administrative access clean-up applications require, such breaches pose significant risks.
Furthermore, CCleaner’s persistent prompts to upgrade to a paid version add to its disruptive nature, feeling more like annoying bloatware than a useful tool. This constant distraction ultimately hinders productivity.
Advanced SystemCare (IObit)
The Do-it-All PC Optimizer Solution

Advanced SystemCare by IObit advertises itself as a comprehensive optimization suite, boasting features such as a registry cleaner, RAM booster, and driver updater. While these functionalities sound appealing, they often do not provide the intended benefits, particularly the registry cleaning feature, which does not contribute to enhanced system speed.
A significant issue with this program is its paradoxical nature regarding performance. Although it promises to free up system resources, user experiences shared on tech forums highlight that its background services, particularly the Performance Monitor, can consume excessive CPU and RAM. This contradicts its advertised purpose, effectively draining system performance.
Moreover, this software employs aggressive upselling tactics that can be intrusive. The push towards installing additional extensions, like IObit Surfing Protection and Ads Removal, only contributes to unwanted system clutter.
Clean Master for PC
A History of Controversial and Unethical Practices

Developed by Cheetah Mobile, Clean Master for PC has garnered attention for its unethical practices. Reports from Beebom highlighted the removal of Cheetah Mobile’s Android applications from the Play Store due to misleading advertising tactics, including deceptive virus alerts that directed users to download their app.
Furthermore, serious allegations have surfaced about the key figures at Cheetah Mobile. The company’s CEO and former president were charged with insider trading, casting further doubt on the integrity of the tools produced by this organization. Trust is paramount when it comes to software installations, and such controversies create skepticism.
Windows Already Has Built-in Optimization Features
Regular system maintenance is essential to keep your computer running smoothly. Files from uninstalled programs, contents of the Recycle Bin, Windows update remnants, and temporary files can accumulate over time. However, using third-party cleaning applications may not be necessary, especially given the capabilities of Windows 11.
Windows 11 includes built-in features such as Storage Sense, which automates the process of clearing out junk files. This eliminates the need for external optimization tools.
Additionally, users can leverage the Microsoft PC Health Check app for insightful overviews of system performance, including storage capacity, battery health, and boot times. This tool provides direct links to relevant system settings, further allowing users to manage their devices effectively. The Task Manager can also be utilized to oversee and limit resource-heavy applications, reinforcing the notion that most cleanup software is redundant. Ultimately, the decision lies in your preferences and needs when it comes to system optimization.
