  Don't worry, it's not a virus.  It's a recursive zip file:

      http://research.swtch.com/zip

  It's data for a testcase, there to make sure the go library routines that
handle archives can deal with a corrupt zip file without crashing.

  The reason that your antivirus gets in a panic about it is that if you email
someone a recursive zip file as an attachment, it'll often crash their
antivirus when it tries to scan inside the zip file, and then other
attachments on the same email will go un-scanned, potentially allowing
something dangerous to get through; this has been a trick used by viruses in
the past to slip past mail scanners.  In the context of the GCC testsuite
however, it's not any kind of threat or problem; just treat it as a false
positive.

    cheers,
