A recent update to Windows Defender is causing slowdowns with "exiftool.exe". One workaround is to add an exclusion to Windows Defender for the "exiftool.exe" used by PhotoGrok (find path in Preferences). Another fix is to install a Windows version of perl and the platform-independent version of ExifTool. Then rename "exiftool" to "exiftool.pl" in the distribution. In PhotoGrok, open the Preferences screen and Browse for the "exiftool.pl" file.
