I got a spam email

Hello Mary,

Possibly, this could be a spam e-mail. Scammers will have a database of e-mail addresses and this can happen if you visit untrustworthy websites, enter your e-mail address there.
Did you perform a scan using AVG Internet Security?
Please share the screenshot of the e-mail (you receive) with the sender's info to check and clarify this further. You can post the screenshot here in your topic. Click on "Answer" & then click on the "Image" [mountain symbol] & follow the instructions.
