2 problems: 
1.  When I try to download an attachment from my Yahoo Mail in Firefox 3, Bdefender gives me this phishing alert: “BD has blocked a website in your browser (URL given).  Are you sure you want to view this site?  BD has  detected a potential phising site.  Click View if only you absolute trust this site.”  I click “View” and a blank page appears – no save/view prompt, no download…  But if I switch off BD antivirus and try to download the attachment, it works fine.  In the same PC, when I try to download the same attachment in Internet Explorer, there is no problem whatsoever.  Could there be any configuration that I need to set in BD for Firefox?  (Sorry I was unable to attach the phishing alert screenshot)
2.  BD 2008 as well as 2009 always warns me some critical issue is pending: viz. I have not done a scan for some time.  A deep scan takes hours.  How do I avoid this energy and time consuming operation every now and then.  
Please help!
