How to uninstall the PC App Store adware-type application
Written by Tomas Meskauskas on (updated)
What kind of software is PC App Store?
PC App Store is a deceptive application claiming to allow easy access to leading software vendors. This functionality may seem legitimate and useful, however, this program is categorized as an unwanted program and adware. This app generates ads, but instead of or alongside the promoted content a variety of harmful software can infiltrate the system.
PC App Store adware overview
After infiltration, PC App Store generates advertisements that can promote deceptive and malicious content. Therefore, trusting these ads can expose your system to the risk of adware, browser hijacker, PUA, trojan, ransomware, and other infections.
In addition to endorsing potentially infectious material, the promoted sites can collect data (which may be personally identifiable) and share it with third-parties (potentially, cyber criminals).
Furthermore, PC App Store likely has data-tracking abilities, as they are common for software of this type. The gathered data may includes: geolocations, language settings, operating system and browser types (e.g., sites visited, pages viewed, search queries, cookies, web beacons, browsing history, usernames/passwords, etc.), personally identifiable details, credit card numbers, and so forth. This sensitive information can be monetized via sale to third-parties or otherwise abused for profit.
PC App Store should not be confused with any genuine software serving as a download platform for applications, updates, or other content. It is highly recommended to only use official and verified sources for downloading; however, even such channels necessitate due caution.
It is not uncommon for cyber criminals to abuse legitimate platforms (e.g., Microsoft Store, Chrome Web Store, Google Play Store, etc.) to distribute unwanted and malicious content. The review teams can be swift in eliminating harmful apps/extensions, which makes this distribution technique lack longevity. However, that does not stop the abuse since the created impression of legitimacy may lure a large number of potential victims.
To summarize, having software like PC App Store installed on your system can lead to further high-risk computer infections, serious privacy issues, financial losses, and even identity theft.

Adware examples
Many adware-type applications claim to provide various useful features and yet none deliver any real value. For instance, Download Checker, Duplicatefinder, OneBlock, and CyberBlock are some examples of adware that redirect to rogue websites, display intrusive advertisements, and gather various Internet browsing-related information.
How did PC App Store install on my computer?
PC App Store has an 'official' promotional webpage. Advertising-supported software is also pushed though scam sites. Most users access such pages via redirects caused by misspelled URLs, sites using rogue advertising networks, intrusive ads, spam browser notifications, or installed adware (with browser force-opening capabilities).
One commonly used method to distribute software like PC App Store is using small 'download programs' (also called 'download clients', 'download managers', 'installers', etc.) on freeware websites and other third-party channels.
These sources use download programs as free services and traffic monetization tools since they offer installation of additional programs together with the chosen software. According to the developers, these promoted apps are 'legitimate and virus-free'; however, reckless download and installation of freeware carry system infection risks.
Intrusive advertisements spread adware as well. Once clicked on, some of the ads can execute scripts to perform download/installation processes without user permission.
How to avoid installation of adware?
We recommend downloading only from official and verified channels. It is just as important to exercise caution when installing content. During the software download/installation procedure, ensure that no additions are included. Use the 'Custom' or 'Advanced' installation options - since they are likely to reveal any hidden apps/extensions and allow you to opt-out.
We also advise being vigilant when browsing since fraudulent and malicious online material usually appears legitimate and harmless. For example, intrusive adverts may look ordinary and innocuous, yet they redirect to highly questionable websites (e.g., gambling, adult-dating, pornography, etc.).
In case of encounters with ads/redirects of this kind, inspect the system and immediately remove all suspicious applications and browser extensions/plug-ins.
If your computer is already infected with PC App Store, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
