Uninstall PCAppStore folder and files

PCAppStore folder, with files therein, has installed itself on my Acer laptop. I use OS MS Edge. I use Norton 360 Platinum Plus 1 and Norton Utilities. All are updated automatically, and system scanned regularly. I have located where this folder is on my laptop. But I want a Norton expert to delete the files. Oddly Norton doesn't seem to be aware of this application. Normal uninstall processes do not work because this application is not shown in installed files list. Can anybody suggest a safe uninstall process?

FWIW!! Having MS do a system reset was a "last resort" solution from where I sit. Taking the least destructive and risk. Having Malwarebytes remove this PUP, would have been a better road to have taken. MBAM is a trusted source alongside Norton, well established here on the community forums. It removes malware that Norton doesn't focus on due to Norton, primarily focusing on protection of the OS.

fwiw ~ as MalwareTips DIY Guide informs [here] and as @SoulAsylum shared. 

PC App Store is installed by the users, whether that is knowingly or not. Often, this type of program is offered through advertisements, cracks for games, or bundled with other software, leaving the user puzzled about where this software came from.
Unfortunately, some free downloads do not adequately disclose that other software will also be installed and you may find that you have installed PC App Store without your knowledge.

You should always pay attention when installing software because often, a software installer includes optional installs. Be very careful what you agree to install.
Always opt for the custom installation and deselect anything that is not familiar, especially optional software that you never wanted to download and install in the first place. It goes without saying that you should not install software that you don’t trust.

Nov1723: Thanks for this SA. However I wanted to stay with trustworthy Norton processes. I finally was able to delete PCAppStore folder and the many sub-folders and files manually. How? Microsoft Support reset my laptop. Unfortunately this reset also removed many of my useful apps, including Norton. So I'm now reinstalling those useful apps. Norton was a disappointment. And my solution is very clumsy, but.

Respectfully, may I ask:  Did you review:  PC App Store thread.

After many frustrating hours trying to get Norton to delete PCAppStore adware, turns out I need to buy some other service from Norton and then they'll uninstall. Very disappointing. I've used Norton for many years and always been looked after. This experience has shaken my faith in Norton. And I still have this adware on my laptop.

Did you run the full system scan with Malwarebytes as suggested? No antiviral company can control where you surf nor what you download. Most times malware gets onto a computer via legit sites where, the site owners are not even aware of the redirects to download unwanted software. Browser settings and system permissions also play a role in what is allowed to download without prompt to the user. Free software, also comes packed with other installers that will download at a later time with the same permissions the original download was given. Just some examples of where and how things arrive on computers without us knowing beforehand.

@Jrogers Download, install and run a FULL scan with Malwarebytes. It should quarantine what it finds and instruct you to reboot for removal. Please post your progress so we may follow-up.
