If you are sure that the file really exists, then it *is* caused by a buggy
virus or spyware definition update. Contact your protection system provider
and report that false-positive. As a temporary workaround, it should help
to add the output folder to the "exclusion" list of your protection
software. This should work around the real-time monitoring bug.
