Clean PC Master

Clean PC Master is unfortunately a bad choice if you are looking for a reliable tool to clean your PC or to protect it. We have found that this application comes from the same creators who are responsible for Zeast PC Tuneup, which just another potentially unwanted program (PUP) as this one is. This PUP, like many similar fake applications, has proven to be more of a scam than a well-functioning useful tool. The goal of this program is not to boost up and safeguard your computer, but to scare you with potentially fake error messages to call a given telephone number. We have seen dozens of similar scams and we know exactly what may happen if you call this number. Let us tell you in more detail what we have discovered about this PUP. What we can already tell you at this point is that we believe that you should remove Clean PC Master from your system to protect your PC from the potential risks this PUP may hold for you.

We have not found a promotional website where you could find an available official installer for this “security” software, which is rather suspicious and strange. How could you trust an application that has no official site and installer availability, not to mention that in this case we are talking about a supposed PC cleaner tool? The sad truth about this PUP is that it is spread on the web in all kinds of shady ways. This trait also does not help us believe that we are dealing with a reliable application here.

Unfortunately, this useless software can show up on your computer without your knowledge or permission. It is possible because, as research and experience show, this PUP can enter your operating system via Trojan droppers, malicious installers, and fake updaters as well. You can mainly find these “nasties” on suspicious file-sharing sites, such as pornographic, torrent, and shareware pages. But you may also click on fake pop-ups about alleged Java or Flash updates, or download an infected bundle from semi-legit software sites. It is quite obvious that you can actually avoid this PUP and the potential additional malware infections, if you do not visit unfamiliar and questionable websites. It is also important, of course, that you do not click on random third-party ads either. If you are in doubt about how this useless application has crawled onto your computer, we advise you to perform a system malware scan right after you delete Clean PC Master. Leaving any other potential threats on board could cause more security issues and your PC would not be safe for you to use.

This PUP is supposed to be a PC cleaner – and it also claims to be the “master” of this – that also has a questionable anti-malware function. It is possible that this application cleans all the temp files from your computer; however, if you want to use the anti-malware option, you will be prompted to buy the application to be able to use it. Unfortunately, if you click on the button to buy it, the program crashes. We have noticed that this application tends to display various fake error messages, including good old BSOD (blue screen of death) messages, which it may obtain through connecting to the database at the 104.237.195.181 IP address. Of course, all these fake error messages have one goal and that is to make you call a supposed “virus removal tech support” telephone number, 1-800-935-0823. We can surely tell you that calling this number will most likely not end well for you. It is possible that you will pay a lot of money for this call for starters. It can also happen that you will be tricked into buying a useless product. What’s more, these schemers may also get personal information out of you that can be used for targeted, customized advertising or even can be sold on the black market. We believe that you do not want to have first-hand experience of any of this; therefore, we suggest that you remove Clean PC Master from your PC.

If you finally decide that this piece of software has nothing to do on your system, we are here to tell you what you can do to sort this out. The bad news is that although this PUP does have an uninstaller, it seems to leave leftovers on your operating system. That is why we recommend manual removal in this case. Please only go for this method if you are aware of the potential risks of making a mistake while editing the Windows Registry database. You can use our step-by-step instructions below this article if you do not mind to get your hands a bit “dirty.” However, it is possible that there are a couple of malware infections on your system; therefore, you need to act now if you do not want to end up with a vulnerable or crippled PC. We suggest that you use a reliable anti-malware program that will not only take care of the present infections, but it will also protect your PC from future attacks.
