I do not know whether this is the right place to report it, and if it is not, please advise where. After downloading from here the latest version of GM for Windows, before installing it, my antivirus program identified a threat called "XML Bomb" with one of the files:
"Object name";"%userprofile%\My Documents\Downloads\ftp_downloads\GraphicsMagick-1.3.13-windows-source.7z:\GraphicsMagick-1.3.13\libxml\test\recurse\goodattr.xml".
Is this a known issue of false positive? I have AVG version 2012.
