My pw got stolen, but I told no one! :S

[Jamesssy]

Hi, I need some help on something. Its not bout wc3, but it could involve programming. Some guy somehow managed to find my password, which is same one for everything. I had regestered at his forums, but I dunno if that means he can get my pw. He is good at coding and stuff. Is that possible, stealing a pw from forum registration?

It was so weird, when he told me my password, because I told NO ONE. Was it cookies? off me regestering on his forums? how he do it?

Edit: my freind just told me how he got it: "all the data of microwebdesign forums is stored in a database, most probly a Mysql database"

and he said the password section is even labeled

He either A) Used a brute forcer to steal it
B) sent you a trojan, you opened it and are screwed.
C) sent you to a website then runs code to steal passwords.

Either way reformat.

if someone is using a ud trojan, chances are it won't be found by a scanner and he sounds too newb to go about removing it manually
