Zen PC Unwanted Application
Written by Tomas Meskauskas on (updated)
What is Zen PC?
Developers present Zen PC as a high quality system optimization/cleaning toolkit. Initially, this app may seem legitimate and useful, however, developers proliferate it using a deceptive marketing method called "bundling", and thus it often infiltrates systems without permission. Due to this infiltration, Zen PC is categorized as a potentially unwanted application (PUA).
Zen PC's main feature is virus clearance. It allows users to perform a 'full system scan' to detect existing malware. Users are presented with a list of potential threats/infections that must be eliminated immediately. The free version of Zen PC is supposedly incapable of doing this and, therefore, users are encouraged to purchase the activation key (also known as the 'full version').
Be aware, however, that it is currently unknown if Zen PC can be trusted. Most "bundled" anti-viruses are fake. They generate misleading results just to scare and trick unsuspecting users into purchasing software that is not needed. In this way, developers generate revenue by extorting money from gullible users.
There is a high probability that Zen PC is one of these fake tools, and thus we advise you to uninstall this application immediately and certainly do not pay for the so-called full version. Note that "bundling" is often used to proliferate several potentially unwanted applications (such as adware and browser hijackers) at once.
Therefore, Zen PC might not be the only PUA that has infiltrated your system. Promoted apps typically deliver intrusive advertisements, cause unwanted redirects, and gather information. As well as eliminating Zen PC, you should uninstall other suspicious applications.
| Name | Zen PC 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. |
There are many potentially unwanted applications that share similarities with Zen PC. By offering 'useful functionality', these programs attempt to attempt to give the impression of legitimacy. Potentially unwanted applications are designed only to generate revenue for the developers, and thus most deliver no real value for regular users.
These applications cause unwanted redirects, deliver intrusive advertisements, gather sensitive information, and promote in-app purchases. Remove them immediately.
How did potentially unwanted applications install on my computer?
As mentioned above, Zen PC is distributed using the "bundling" method. Therefore, although it has an official download/promotion website, Zen PC often infiltrates systems without permission. "Bundling" is essentially stealth installation of third party apps together with regular software/apps.
Developers hide "bundled" applications within "Custom/Advanced" settings (or other sections) of the download/installation processes. Furthermore, many users rush these procedures and skip steps - behavior that is likely to lead to inadvertent installation of potentially unwanted applications.
How to avoid installation of potentially unwanted applications?
Be very careful when downloading and installing software. Select "Custom/Advanced" settings, carefully analyze each step, and cancel all additionally-included programs.
Furthermore, download apps from official sources only (using direct download links) and avoid using third party downloaders/installers, since developers monetize them by "bundling" potentially unwanted applications.
Rogue apps are distributed using intrusive advertisements that redirect to malicious sites and run scripts that download and install PUAs/malware. These ads are usually delivered by adware-type applications. Therefore, if you encounter them, immediately remove all suspicious applications/browser plug-ins.
The main reasons for computer infections are poor knowledge and careless behavior. Caution is the key to safety. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
