I recently reformatted my computer because it was having problems starting up; it wiped everything from the drive.
This morning I tried logging into my Facebook. Usually it will give me an email stating that there was a login from my normal location (Canada), but this time it said there was a login from New Zealand. Right away I changed my Facebook password and then received an email saying my password had been changed from California.
Then I looked at my recent activity of my email, and it said there was a login from Miami.
I have no clue what is going on or why all these logins are coming from different locations.
