This is something that was highlighted 1 or 2 years ago. The following files are being shown as possible malware by RSFirewall scans:
.DS_Store.DS_Store (found in modules/mod_zentools2/tmpl and modules/mod_zentools2/settings/)
.csslintrc (found in templates/buildr/zengrid/libs/frameworks/bootstrap3/)
.csscomb.json (found in templates/buildr/zengrid/libs/frameworks/bootstrap3/)
A screenshot is attached showing the RSFirewall scan result.
I think previously JoomlaBamboo confirmed these files are not malware and that they would be removed in future updates.
What purpose do the files serve and are there any plans to remove them from future updates?
