Master PC Cleaner virus has been described as a fake system optimizer. Similar performance boosters have become extremely popular among developers and we detect comparable unreliable applications regularly. PC Smart Cleanup and Advance-System-Care promise to provide users with utmost care to keep their PCs running smooth, fast and error-free. The tool is expected to work on Windows 10, 8, 7, Vista and XP.
Master PC Cleaner is supposed to service its clients as a registry cleaner, add-on remover and startup manager. Even though developers promise to fix invalid registry entries, remove adware and improve boot time, this rogue system optimizer will only show users forged results to scans and hope to trick people into purchasing full versions of these tools. It has received a spot among potentially unwanted programs (PUPs) (What is a PUP?).
We downloaded a mpclsetup.exe which is an installer of Master PC Cleaner potentially unwanted program. After running it through a number of scanners, the file was labeled as Program.Unwanted.2260, malicious (high confidence), PUP.Optional.MasterPCCleaner and Suspicious_GEN.F47V0929 (VirusTotal analysis). Therefore, we determine that this tool is a potentially unwanted program. Even though not necessarily malicious, it has features that make it untrustworthy and potentially dangerous (The battle with potentially unwanted programs).
Master PC Cleaner PUP is an unwanted tool, normally installed with bundles of programs
Master PC Cleaner fake tool is not a program that users should continue on using. Its developers offer a free version only for one reason: to convince people that their operating systems are severely infected and should be cleaned with a full version. Similar statements are made by authors of Magic PC Cleaner. The End User License Agreement states that “the software will be installed as a free trial with limited functionality and will work with all of its features after the purchase of a license key”. This means that users won’t be able to fix any issues until the full version of Master PC Cleaner program is purchased.
However, false positives are often used by rogue system optimizers/anti-malware tools. Disturbing amount of system issues can be labeled as high-risk. However, all of these problems could be completely made up. Therefore, software from suspicious developers should never be trusted. While we investigated the mpclsetup.exe installer, we figured out that Master PC Cleaner PUP could be related with Win Tuneup Pro and Secure PC Tuneup rogue security software.
Master PC Cleaner is indicated to be worthy of $33,95. However, we do not recommend users to make this deal because they will be downloading a suspicious tool that will not offer top-notch functions. In fact, the premium version might be just as useless as the free one. Additionally, the tool might not protect its clients from malware infections. The free version will be launched automatically since the tool will have inserted an entry in the Windows Registry.
Lastly, we should emphasize that potentially unwanted programs differ from malware parasites. PUPs are not as dangerous and they should not initiate malicious activity. However, their poor-quality and suspicious marketing strategies are definitely questioned by security researchers. System optimizers have been confirmed as problematic and should receive many improvements before being worthy of their official prices (System maintenance is important but do not fall for fake helpers).
How can potentially unwanted programs be avoided?
Master PC Cleaner suspicious tool could end up in operating systems in bundles of programs. While you are installing any type of application, always choose the installer to run in advanced or custom mode. If you notice that system optimizers are being offered to you as supplementary, please refuse this recommendation.
This sneaky method is exploited by many developers that are attempting to distribute PUPs or even malware parasites. If your operating system accidentally starts featuring programs that you do not recognize, do not delay their removal from Control Panel. If the tool still continues to be launched after devices are rebooted, we suggest running a scan with Spyhunter and allowing it to remove the suspicious tool fully.
