virus alert on safari browser screen
I'm using High Sierra 10.13.5 (17F77) on MacBook. After leaving the safari browser open for awhile on a blank opening page, I got a virus alert warning. I didn't do a screen shot but it looked very official with a trojan name and code. I was suspect just because I don't think Apple scans my laptop for malware or viruses. I've never signed up for any protection service. I have downloaded and used the free Dr. Antivirus app. I ran it after closing down safari and it found nothing. I thought it was weird that the browser was not on any page.
MacBook Pro (13-inch, 2017, 2 TBT3), macOS High Sierra (10.13.5)
