User locked out from signing in

I am getting the “User locked out from signing in” email every day now.

I would simply ban the user IP address, however, it this is coming from my IP!

This really concerns me. What could it be? What should I do?

I scanned my computer for problems but nothing came up.

I noticed they are continually trying different user names, and this seems like some automated attack.

I use strong usernames and passwords, so I do not think they will ever get in.

But of course, I want to get to the bottom of this and stop the attack.
