ALL: I've been running Avast Security Pro on my Macbook Pro for some months, but this morning I received an email from a purported hacker who says he's breached my email & installed a Trojan onto the sysem. What's interesting is that he uses my email address in his message as well as an old password I used some years ago (but not recently). Of course, he's threatening to share my browsing activity with the world and wipe my computer clean without a paid ransom in Bitcoin. I run the Avast Security Pro, Malwarebytes (basic) and Oversight 1.2.0. No malware found on these scans: Is there any chance this email & his breach are legit? All thanks for your help.
