In my /var/www/html many files with strange chars appeared suddenly.
Below is a sample. Any idea why they appeared (attack ?, app dump ? file system error ?) and how to remove them (there are other files and content I need to preserve).
All files are owned by apache. Web server is running pimcore.
I tried with rm 'file' rm "file" but no success.
# rm "M?."
rm: cannot remove âM?.â: No such file or directory
Any help greatly appreciated.
