When I build a WiX project in Visual Studio 2015 that has a pre-build or

requires that I manually tell AVG to allow this operation each time I build
the project.

As I investigated the issue, I found that the WiX build event is converted
to a file in C:\Users\<username>\AppData\Local named "tmp*.exec.cmd" where
'*' appears to be a random GUID that changes with each build
(i.e., tmpe64b16a499eb4d85ab32156b25079ed5.exec.cmd)  This GUID doesn't
appear to be associated with any GUID in the WiX project that I can find.

If anyone has found a different solution to this problem, I am open to
alternative options.
