I am getting mass amounts... 50 to 100 messages a day of "undeliverable mail" that I did not send.All with the same Subject line... mass mailing obviously.
Zone Alarm Suite comes back clean.
Has someone stolen my email address and sending mass mailings as me or have they hijacked my computer and using my computer for these mailings?
How do I find out?
I don't know where to look if Zone Alarm is coming back clean.

Operating System:Windows XP Pro
Product Name:ZoneAlarm Internet Security Suite
Software Version:7.0
