Guys, I don't know what happened but my desktop PC got hacked, someone is using my msn and sending spam messages to my friends, sometimes sends links that contain virus. I just finish changing all my passwords and reinstalled the pc again but guess what, when I login to the internet, I get this message from norton that someone tried to "attack" my PC and they manage to stop it. In their message which they classified as "high risk", they detects the threat coming from this IP address - 22.214.171.124 . Where is it from and what can I do to hit this guy back? And why after reinstalling the whole C drive I still getting attack? The threat was from system32 folder, an exe. file there that I can't delete because Windows message "Protected File" stuff. What should I do? Heeeelp needed!
