Not sure, but if you have broadband/always-on internet connectivity, you owe it to yourself to get ZoneAlarm, a free firewall program for your PC. Don't have the website handy, but it should show up in a Google search. It basically intercepts all attempts to access your computer via the internet. It also intercepts all outgoing network packets from your computer and only allows those that you chose to pass (such as Internet Explorer and Outlook). This would prevent a virus on your PC from sending personal info over the internet back to the virus writer. Good luck!
