I've found the same. I can get past Windows Defender but Norton keeps deleting it (it says fewer than 5 people with Norton have used the application!).
you can uninstall it, many times it been shown that it doesnt not protect your computer and the "scans" are just listing the average number of user. It will only look for the same file (by name or code) as a virus, if it isnt a virus it will delete it.
