Possible attempt to hack email

Anybody get a very professional looking email as follows :

"(Name) You shared a document to Review" and the email asks you to to click on a file to review a document.

I got one , I thought it was a bone fide business proposal as it came from a reliable business contact's email address.

Now I am getting phone calls and emails from people on my email list saying they have received the same email from me .

Obviously I'm worried about my contacts' and my own online security

Any advice ?

Change your passwords immediately.

Set up two-factor authentication.

Was it really from the person's actual email address or was the alias formatted to make it look like it was? Did you click on it?

Any decent email service/client, or even the likes of free services like Hotmail/Outlook.com or Gmail, should generally catch this sort of thing and flag it as potential spam. Didn't your system do this?

Why would you click on it if it's saying you shared a document for review if you knew that you didn't?

@Sharpie - Did you open that email via your phone or laptop / computer / tablet ?

The virus might be on that machine and not just your email. Have you a virus scanner that you can run ?
