PC App Store removal instructions

What is PC App Store?

PC App Store is a deceptive application claiming to keep installed software up-to-date. This functionality may seem legitimate and useful, however, this program is categorized as a potentially unwanted program (PUP) and adware. The developers of this rogue app employ a deceptive software marketing method called 'bundling' (stealth installation of third party applications together with the chosen software) to install PC App Store without users' consent. After infiltration, PC App Store generates pop-ups that offer various software updates, however, the update process includes installation of additional programs (mostly adware) that are usually hidden under the 'Custom' or 'Advanced' options. Therefore, accepting these updates exposes your system to risk of infection.

PC App Store adware

Many adware-type applications claim to provide various useful features and yet none deliver any real value. For instance, ShoppinGate, Coupons Vault, SmartWallet, and Shopzy claim to save time and money while shopping online, however, they often redirect to rogue websites, display intrusive advertisements, and gather various Internet browsing-related information. The type of collected data usually includes geolocations, language settings, operating system and browser types (including data: websites visited, pages viewed, search queries, cookies, web beacons, and history). In addition, many advertisements are generated such as banners, pop-ups, coupon, and in-text ads. Be aware that these displayed ads often redirect to bogus websites containing infectious content and the collected data (which may be personally identifiable) is shared with third parties. Therefore, having adware-type applications installed on your system can lead to further high-risk computer infections and/or serious privacy issues. Although PC App Store is not technically a virus or malware, it is used to distribute rogue applications, and therefore, you are strongly advised to uninstall this application from your system.

Research shows that most adware is distributed using small 'download programs' (also called 'download clients', 'download managers', 'installers', and so on) on freeware download websites such as soft32.com, softonic.com, downloads.com, and many others. Download programs are used by these websites' 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 risks system infection with adware or malware. This situation can be avoided by closely analysing each step of the free software download procedure and ensuring that no additional applications are included. Furthermore, downloaded software should be installed with the 'Custom' or 'Advanced' options - this will reveal any hidden apps listed for installation and allow you to opt-out. If you have installed PC App Store, the following removal guide will help you to eliminate this PUP from your system.
