I don't use a third party email provider as I run my own mail servers but I've looked at Fastmail and they seem to be very security conscious, which is both rare and a good thing.
As well as scoring highly on the
SSL/TLS and web server security tests at High-Tech Bridge, they offer a good range of two factor authentication options including hardware U2F keys such as the
Yubico one, which can be bought on Amazon, and the
Duo authentication mobile phone app (free from Google Play and iTunes App stores).
The advantage of two factor authentication is that if you find yourself needing to access your email by webmail on an unfamiliar computer, at an internet caf� for example, and it turns out that the computer has malware and is logging key strokes, your email account still can't be compromised.
Sadly, Mike, it's a bit too late for you as you already seem to be infected with malware
Please note that SMS two factor authentication is no longer considered secure - see
NIST declares the age of SMS-based 2-factor authentication over.
