....and are you assured your PC is risk-free?
maybe, you can ask Chat with Official Norton Support to review your NPE scan log.....to assure you.
Just me. I would never trust NPE scan nor act based upon NPE scan (nor trust System Restore Point will be created nor trust restore point will "fix-whatever"). Just saying.
NPE does not detect malware (that is what Norton Security is for), it presents you with a list of files that could be malware. It is meant to be run when your Norton program does not detect anything malicious but you still suspect that something may be acting suspiciously on your PC. If there doesn't appear to be anything wrong, the results returned by NPE will almost always be safe files that belong to applications on your system. NPE doesn't tell you much about a file because it really doesn't know much about the files it presents - that's the whole point, if Norton knew whether the file was actually malicious or not you would not have to run NPE, as Norton Security would catch it if it was malicious and NPE would not flag it if it was a known good file.

FWIW ~ Norton Community often suggests Malwarebytes Free for second opinion on-demand scanner. YMMV

maybe, you can Copy to Clipboard your blue items (Norton Power Eraser - 3 new risks) (for example)
