Bloodhound.PDF.9 virus dedected and blocked at website. Do I need to take further actions?

When I entered this website - www.mania.com I got a notice from my NIS 2008 that an intrustion attempt was blocked, and then that something called Bloodhound.PDF.9 was blocked and was "resolved".  When I checked the description, under "Recommended Action", it said "RESOLVED - NO ACTION".  So is there anything else I need to do?  Under "Filename" it said that was called "acra9ac.tmp" under "c:\documents and settings\"my name"\local setti...".  Does that mean the file is still there?

 

Also the intrusion detection was coming from an Attacking Computer called hirsutus.com (193.33.61.224, 80).  Traffic Description - TCP, www-http.  Risk name - HTTP Acrobat PDF Suspicious File Download.  Now my Acrobat 8 did open, but it said it couldnt open the file and asked me whether I wanted to cancel or reload.  So I clicked cancel and Acrobat closed.

 

Windows pop-up blocker also came up, but an ad window did show up afterwards.  This ad always shows up on this website, never got an intrusion attempt notice before with this.
