The One Click PC Cleaner is not a reliable tool that can clean your system from junk files and fix your Registry errors. This program is a threat designed to collect your money. The One Click PC Cleaner doesn't perform like popular keylogging Trojans that record your account credentials in silence. Instead, the One Click PC Cleaner makes your PC unusable and displays a series of security warnings. These false alerts claim that you are infected with advanced threats, which is ironically true. However, they suggest you dial a specific phone number, which is not the proper course of action. If you call 888-416-7172, you will not receive help from qualified experts. You will only get in touch with manipulative con artists who may demand hefty commissions in exchange for nothing. The developers of the One Click PC Cleaner spread it via a few well-known delivery tactics. There are some Web pages that host the One Click PC Cleaner but describe it as a reliable security tool. If you notice the symptoms of this infection, but you have not installed the One Click PC Cleaner manually, then it might have been brought to your system by some freeware. The interface of this unreliable tool is pretty straightforward: you will notice six different checkboxes, which should allow you to choose which issues to resolve. The One Click PC Cleaner is expected to clean temporary files, fix Registry errors, repair firewall problems, delete the browser cache, etc. In reality, however, the One Click PC Cleaner cannot achieve any of the mentioned features. Shortly after the One Click PC Cleaner reaches your system, it may change the configuration of your Operating System (OS), making it impossible for you to launch the Task Manager. Afterward, the One Click PC Cleaner may show Blue Screen of Death (BSoD) alerts that will cover your whole screen. You may be unable to terminate them unless you restart the PC. To delete the One Click PC Cleaner, you should use a credible security solution.
