I couldn't have said it better myself.  I've had three viruses in 29
years
and only one of them was my own fault. I've spent hours trying to explain
people that trusting an antivirus solution is unfortunate at best.

Ok.  You get it your way :-)  Disable antivirus, checkout, and then add the
offending file to the exclusion list.

A better rule of thumb I would say is to exclude the entire source and 
build directories from antivirus. On-access file scan hurts build times 
a fair amount, and I really doubt that any of your source code is going 
to have viruses in them :-P

Well, I actually ended up writing a compromise of compromises:

The recommended course of action is that you do this:

#. Disable your anti-virus solution.
#. Pull the LLVM test suite from the `LLVM website
<http://www.llvm.org>`_.
#. Add the file
``%LLVMDIR%\\projects\\test-suite\\MultiSource\\Applications\\ClamAV\\inputs\\rtf-test\\rtf1.rtf``
   to your anti-virus ignore list.  Alternatively, you can, at your own
   responsibility, add the entire ``%LLVMDIR%`` directory tree to your
   anti-virus solution's ignore list.  This will likely speed up your
   builds as the anti-virus solution does not need to inspect each and every
   file over and over again while building.

So, we're covered in all cases.  I think the antivirus was the reason that
an LLVM build just took about an hour on my Core i7.  Normally it only
takes like twenty or thirty minutes IF I recall correctly.
