PC TuneUp Maestro Unwanted Application
Written by Tomas Meskauskas on (updated)
What is PC TuneUp Maestro?
PC TuneUp Maestro developers promote this app as a legitimate tool that allows users to enhance PC performance and stability, improve Windows Startup performance, and improve performance of the operating system and programs.
Initially, this app may seem legitimate and useful tool, however, developers distribute PC TuneUp Maestro using the "bundling" method (a deceptive marketing method) and thus it is often installed by users unintentionally. These programs are categorized as potentially unwanted applications (PUAs).
The main function of PC TuneUp Maestro is to scan the system for various issues and fix them, however, the 'free version' only scans the system and provides no fixes - this requires users to purchase the so-called 'full version'.
Programs distributed using the "bundling" method cannot be fully trusted and there is no guarantee that any paid version will fix the issues or improve PC performance. Like most apps of this type, PC TuneUp Maestro will probably find 'issues' (potentially, many), but these untrustworthy apps often display fake scan results to trick users into purchasing rogue software.
PC TuneUp Maestro might be one of these dubious products. Even if it claims to have fixed detected issues after the 'full version' is purchased, this does not necessarily mean that the issues were genuine in the first place or that any 'fix' has taken place. "Bundled" apps are often useless, and so we recommend that you consider uninstalling PC TuneUp Maestro.
Also check for other potentially unwanted applications installed - it is possible that PC TuneUp Maestro was not the only app bundled into a 'setup' that was used to install it. The "bundling" method is used to distribute various browser hijackers and adware-type programs that are designed to gather data, cause unwanted redirects, and deliver advertisements.
| Name | PC TuneUp Maestro potentially unwanted application |
| Threat Type | PUP (potentially unwanted program), PUA (potentially unwanted application) |
| Symptoms | A program that you don't recall installing suddenly appeared on your computer. New application is performing computer scans and displays warning messages about found issues. Asks for payment in order to eliminate the supposedly found errors. |
| Distribution methods | Deceptive pop-up ads, free software installers (bundling), fake flash player installers. |
| Damage | Monetary loss (unnecessary purchase of fake software), unwanted warning pop-ups, slow computer performance. |
| Malware Removal (Windows) | To eliminate possible malware infections, scan your computer with legitimate antivirus software. Our security researchers recommend using Combo Cleaner. |
Hundreds of potentially unwanted applications distributed using the "bundling" method are described as 'useful', but most PUAs do not provide the functions promised and are designed only to generate revenue for their developers by collecting data, delivering ads, causing unwanted redirects, and so on.
How did potentially unwanted applications install on my computer?
It is possible to download PC TuneUp Maestro from its official website, however, many users install it inadvertently. Software developers use the "bundling" method to trick users into installing PUAs, including PC TuneUp Maestro. Bundling is stealth installation of potentially unwanted apps with regular software.
Developers achieve this by hiding rogue apps in "Custom", "Advanced" or other settings of this type. In most cases, information about the presence of bundled apps is not properly disclosed. The most common reason for these unwanted installations is rushing installation process and skipping steps.
Developers are aware that some users do not check the aforementioned settings or simply skip steps, and they use this behaviour to their advantage.
How to avoid installation of potentially unwanted applications?
We strongly recommend that you download software from official websites and using direct links only. Avoid using third party software downloaders, torrents, and other similar sources. Pay attention to details when installing software - do not skip installation steps, check all available "Custom", "Advanced" and other similar options of the installation processes.
Opt-out of "bundled"/additionally-included apps or programs and only then finish the installation. Bear in mind that developers of intrusive ads invest time and money to make malicious ads seem legitimate, however, once clicked, they cause unwanted redirects that can result in serious problems.
If you encounter ads that redirect you to gambling, pornography, adult dating, and other similar websites, check the list of installed plug-ins, extensions, and add-ons on your browser and remove any suspicious/unknown/unwanted entries immediately. Also check the list of installed programs on your computer and remove suspicious entries.
If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
