bloodhound.pdf.10 with a.exe virus

Hello,

I just got my first virus on my pc yesterday.  I went to a foxnews.com website that had a link to the SUN newspaper in England (fyi, if you want to reproduce this, go find the story about clown feet and shoes...really).  When I loaded this page, there were many clicks (usually happens when pop-ups are downloaded which I block).  In fact there were so many clicks I got concerned and disconnected from the ethernet.  But it was too late.  I saw in task manager the file a.exe running and then it tried to connect to the internet which my firewall blocked.  I killed a.exe.  It had been installed on my Desktop page.  Norton identified a temp file in my LOCAL TEMP directory as bloodhound.pdf.10 but it never identified the a.exe file which was obviously bad.  I deleted it.  So what does a.exe do?  Did it install anything on my system?   I know it ran as I saw it in taskmanager.  Sorry, the file a.exe is deleted.
