My computer was hacked my ip address and now I'm seeing command prompts flashing on a brand new computer. I closed my old email account a Trojan horse and a malicious fake tech support company calling themselves Code Red.hacked my computer and installed malware. I put the old computer in the shop and bought another one. The new one is now flashing command prompts. except I see that the message is short and contains no passwords. Any advice anyone? I'm embarrassed that I let a hacker in; it happened at a moment when I was off guard.
