Guild Wars 2

I created this account when I first played GW + 1 or 2 of the expansions. Hardly ever played since I couldn’t really get a real feel with the game. I still don’t play much so when i got this email I was quite surprised. I used AVG (registered bought version 2013)

Any suggestion what I can do or should I just keep an eye out for another verification email?
I bought GW2 via this site.

I changed password ofcourse.
Are there any known keyloggers for this game. My AV never found anything. Ifthere are keyloggers for this game then nomatter how many times I change my PW it will still be send to them.

Also, is it possble to allow only login from a certain IP and nowhere else? It’s not like im moving to another country.
