That's the forum with our security mavens and more.
My thought here is to not rely on just one anti-virus tool. Scan with items like Free AVG AntiSpyware and if you can, Housecall. These coexist well with more if not all the usual antivirus programs.
Next, any "viewing" of email in Outlook (any version) is perilous as you have discovered. I alway suggest to turn off email previews and never open any unsolicited emails since Outlook (any version) is still open to possible code execution just by viewing the email.
Hope to see you in the Security Forum,
