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?
