|Sounds like it was a bogus email (they are made to look like the real thing) so you might now have a virus.|
Start with downloading, installing and running MalwareBytes freebie from here:
Let it fix all it finds and let me know if it unearths anything much.
Never click links on emails involving accounts - always use the email address you use normally to check up on things. If it said something like Dear Customer rather than your name then it was definitely a scam.
Always pop back and let us know the outcome - thanks
