What makes you think the suspicious file compromised your system? The av stopped it as far as I understand it.

The suspected file is probably stored in the mail storage folder that’s why it shows up after a fresh installation of Vista.

Is this alert about an attached file or about the email its self? I understand you trust the source who sent the email.
