PC Booster, in essence, is a type of software that is marketed as a tool to enhance computer performance. It purports to optimize your Personal Computer (PC) by cleaning up junk files, fixing registry errors, and improving overall system speed. However, contrary to these claims, PC Booster is often classified as Potentially Unwanted Program (PUP) due to its malevolent behavior. This software, rather than improving your system’s performance, can potentially lead to various computer-related issues, including system slowdowns, intrusive advertisements, and unauthorized changes to your system settings. PC Booster infects computers mainly through bundled installations. This typically occurs when a user installs a free software package without fully understanding what it entails. The PC Booster software is often hidden within the ‘Advanced’ or ‘Custom’ installation settings of these free software packages. Once installed, it can start causing various problems. Moreover, PC Booster can infect computers by employing deceptive advertising techniques. For instance, it may display pop-up alerts warning about imaginary PC issues and offering to fix them. When the user clicks on these alerts, the PC Booster software gets downloaded and installed. Thus, it is always advisable to exercise caution while installing new software and to steer clear of suspicious pop-up ads to prevent PC Booster and similar programs from infecting your computer.
