Online scanner results

I run an online scanner periodically to check for viruses that Norton misses.

My laptop (windows 10 home) has been behaving oddly after I took it on a vacation with me and used public wifi

The scanner popped up this potentially unwanted application:

C:\Program Files\Norton Security\Engine\22.21.11.46\NCrypt.exe

Is this legitimately part of Norton or is it a problem?
