I went back to the email and hovered over the link and it confirmed to me that it was, in fact, a dodgy link.
Luckily, I knew what to do.
I closed all browser windows, and shut down my computer.
I’m also lucky enough to have a second computer. I logged in there and immediately changed my password.
I then set up every single account I have with 2-factor-authentication where I could and also bought an anti-virus programme that allows me to protect up to 5 devices.
