What is Master PC Cleaner? And how does it function?

Master PC Cleaner is a PC optimization program advertised to speed up Window PC’s performance as well as solve several system issues and errors by cleaning up the registry and add-ons and manage startup. Despite its seemingly impeccable advertisement, security experts deemed this program to be potentially dangerous to your computer which is why it belongs to the group of potentially unwanted programs or PUPs.
Some computer users often refer to this program as the Master PC Cleaner virus as it is capable of entering your computer system without any permission from you. Just to be clear, this program isn’t really confirmed to be malicious. However, researchers find this program to be highly suspicious as it initiates system scans which gives exaggerated results – it display tons of problems in your computer that needs to be fixed. What security experts find odd is that the program does not provide any additional details about the problems it has detected. It often lists hundreds of system issues that according to them can only be fixed if you purchase the program’s license. And before you make any hasty judgments and purchase the program, hold your horses as you will be only wasting your money for a program that is not even proven to be effective and good. There are so many risks you can be facing if you decide to purchase its licensed version – for one, since you will be paying them, you will be providing your credit card information which means that you will be giving them your credit card information, thus, putting your confidential information at risk. Not to mention that this unwanted program might suggest deleting or modifying important registry entries which could seriously harm your computer and can cause even more problems. So if you’re really in desperate need of a PC optimization tool, you can try PC Cleaner Pro – it is a trusted and reliable PC optimization tool that improves your computer’s performance as well as fixes system issues.
