How to remove Global PC Cleaner Pro from a computer
Written by Tomas Meskauskas on
What kind of application is Global PC Cleaner Pro?
Global PC Cleaner Pro is advertised as a powerful tool designed to optimize a computer's performance and clean up unnecessary files and programs that slow down its speed. However, while investigating the Global PC Cleaner Pro application, we found that multiple security vendors detect this app (and its installer) as malicious.
Global PC Cleaner Pro overview
Global PC Cleaner Pro supposedly allows users to scan a computer and repair issues, remove unwanted items, install and uninstall apps, boost RAM, and improve PC performance in other ways. While running a system scan, it "detects" thousands of errors and urges users to call the provided "support" number (+1 866-488-5279) for assistance.
It also displays a second pop-up message claiming that it has detected malware in a file downloaded from the Internet. That message provides the number of infected files and urges users to call the same number to fix the issue.
Once contacted, individuals behind this app may urge users to pay for unnecessary tech support services or ask to provide sensitive information, such as credit card details or login credentials. Also, they may instruct users to install a remote administration tool to grant them remote access to computers.
Providing remote access to computers can lead to the installation of malware (e.g., ransomware or crypto-mining malware). Thus, it is important not to trust apps like Global PC Cleaner Pro and never call suspicious technical support numbers. A couple of examples of scams where users are asked to provide remote access to their computers are TeamViewer scam and UltraViewer scam.

Similar applications in general
Fake apps that claim to detect viruses, errors, and other issues on a device are a common type of scam. These apps often use scare tactics to convince users that their device is infected or in danger. However, in reality, the app may be malicious and may actually introduce viruses or other malware onto a device.
In some cases, these apps may also attempt to trick users into paying for unnecessary services or providing sensitive information. Examples of apps that are more or less similar to Global PC Cleaner Pro are PixelSee, Getmut Cleaner, and Broom Cleaner.
How did unwanted applications install on my computer?
Users may install fake apps that claim to detect viruses, errors, and other issues on their devices in a few different ways. One common method is through malicious websites or pop-up ads that encourage users to download and install the app. These websites or ads may claim that the user's device is infected or in danger and the app is necessary to fix the problem.
Another method is through social engineering tactics such as phishing emails or text messages that trick users into downloading and installing the app. These messages may seem to be from a legitimate source, such as a software company or technical support provider, and may use scare tactics or urgent language to convince the user to take action.
Finally, users may also inadvertently install fake apps when attempting to download a legitimate app from an untrusted source. For example, a user may search for a popular app online and unwittingly download a fake version that appears real but contains malware or other malicious software.
How to avoid installation of unwanted applications?
In order to avoid installing shady apps, it is important to stick to reputable app stores such as the Apple App Store, Google Play Store, or official websites and to be cautious when downloading apps from unknown or untrusted sources. Users should also be wary of unsolicited messages or pop-ups encouraging them to download and install any software.
It is also recommended to check installers for unwanted apps before finishing installations and avoid clicking ads and links on dubious sites. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
