How to manually remove "exploit.pdf-js.gen", how to manually remove "exploit.pdf-js.gen"

Question

I just installed BitDefender Anti-virus and did a system scan.  The results turned out that I have a number of threats found on my backup volume (external drive for time machine to back up on).  The threats are all  "exploit.pdf-js.gen".  However, I got a message from BitDefender saying that Access was denied to these infected files and that Delete of these files failed. 
I tried following the path to these files but once I got to /Users/["my name"]/Library, I don't see the "Library" folder in ["my name"] folder.  It does, however, appear that these threats are found in some emails as attachments.  I also tried looking for these email attachments in iMail but they are nowhere in there.
How do I manually get rid of them?  Thanks very much!  I really need to get rid of these files because from the file names of these suspicious pdfs, they appear to be sent on my computer for rather sensitive political reasons... 
Thanks!

Answer 1

The knee-jerk reaction from Mr. Hemphill that there are no Mac viruses (yes, there are no Mac viruses, but viruses are not to be confused with malware, which Macs do get) and AV is never needed on a Mac will not suffice.
According to Microsoft Malware Protection, this is real malware that came via infected pdfs, which exploited a vulnerability in earlier versions of Adobe Reader. It is, apparently, cross-platform, Mac/Windows. How effective or infectious it actually is on a Mac I also don't know. It may be cross platform, but do nothing on a Mac, but I'd still get rid of it.
And I don't know if it could still be active on your system. But you should remove those files.
You'll see that different AV programs have given it different names.
The vulnerability affects Adobe Reader and Acrobat 9.x before 9.3, and 8.x before 8.2 on Windows and Mac OS X.

I'm not seeing anything like it for pdf in the ClamX catalog. Whether this means that ClamX omitted it, it's listed under some name without pdf, or they don't think it will run on a Mac, I don't know.
