ZoneAlarm reported a new virus in an e-mail which it had quarantined. I could not open the inbox in Thunderbird so I closed the program and re-opened it - now the only e-mail it showed was the one with the virus - it had deleted ALL THE OTHER E-MAILS! What the **bleep** is this about? How do I retrieve my e-mails? I have history from family, friends and business which you have allowed to be deleted. How do I get it back?

Despite your dropdowns I am using Zone0-Alarm Security Suite 7.0.483 with Windows XP SP2

Operating System:Windows XP Pro
