Very confused as to what has happened
I'll keep it short and simple. While playing a full screen game, I tried the Windows Screenshot tool (Win+Alt+PrntScrn). After finishing the gaming session, in the notifications tab to the side, it allowed me to view the screenshot. I clicked on the notification, and it was loading, but only allowed me to view and edit the screenshot via signing in with an Xbox Live account, which I was not going to do. I looked for the screenshot, and found it in a capture gallery. Before I shut down the computer, I scanned my device with the Norton Full System Scan and the Power Eraser tool, like always (absolute fanatic about my security). The Full system scan came in clean, but the Power Eraser brought up three files to my attention. The other two were a little complex, but one I remember was WinStore.Preview.dll. I discovered that there were forums on different websites stating that these were either malware, or critical to running the Windows Store App. The cloud scan on these yielded no results. So, I removed them, but then I got the message that I wasn't allowed to because of my restore point service being deactivated.. so after researching this, I opened the menu that allowed me to change it, but I didn't see the option to turn off what was disabling my Restore Point services.. so, I closed that out, and tried to remove them again, which it somehow did successfully. And noting that two of the files contained "WinApp" and "WinStore" respectively, I tried to open up the Windows store, to see if it still worked.. which, it did not. It lingered for a few seconds each time, and then crashed. Not really sure what has happened, but I'd love an answer. (This has happened on another device)
