Popup keeps appearing asking for email pwd.
Visited a state park website & tried to email a map. 2 weeks later started getting a popup with an "@" asking for email pwd. Shows the email address i was trying to send map to. Behind it another popup of the map.
I close it but it keeps reappearing. Malaware Bytes didn't find anything. It's just a nuisance but i'd like to get rid of it.
