Yesterday when I logged on to Facebook, I got a message that they found something unfamiliar with my account. My account was accessed by a Windows XP computer and it was a U.S. IP address. So they immediately asked me to change my password and I did it. Today, it was Windows 7 PC and from U.K. IP address. So I again changed my password to a long and complicated one. I dont know who's the bloody hacker and how can he access my FB account. I have no virus or any infection on my PC as such, my PC is well secured with anti-virus and anti-spyware. If that's the case, I m afraid I will lose my FB account soon..
