Hi, I currently use Windows XP. I have a wireless internet and I believe my computer has been hacked by someone. I believe that all my passwords and stuff when I type them in, are being emailed to some other person and they are getting into my accounts. Due to the fact that I do my banking on the internet, this could be a real issue. Does anyone know of how I can stop this type of activity? I use Zone Alarm the Firewall. Also I found a .CS (comma-seperated-something-a-rather) file listing all of my accounts names and passwords in the C:\Windows\System32\catroot directory, that I did not put there. I found this as I downloaded a program to detect malicious activity on the PC called Microsoft Malicous Detection Tool that found this file.

Thankyou for all advice.
