finding files on my machine

Hi,
Back with one similar kind of question.
Outlook express had deleted some attachments which it thought were  harmful 
virus. I want to know were can I go and look for those files. Please if someone
can right the complete path of that folder. Some of the files which the outlook 
express the smart man has deleted were some very important attachments
and I cannot even request that person to resend the mail.
Now I am also confused whether I should let the check box in the securities tab 
which says Do not allow attachments to be saved or opened that could
potentially be a virus. Please tell me in general whether this check box should 
be checked or un checked.
Thanks,
Sanjay
