Answer 1

1. Find all files named index.php using the linux find command.
2. Search in the files for the string if ( !class_exists( 'WPPluginsOptions' ) ) using the linux grep command with the -l flag. (Only output files that match what you are looking for )
3. Use the linux xargs command to send the list of files from the grep command to the linux rm command.

All together.

find -L /var/www -iname "index.php" -exec egrep -l 'if ( !class_exists( '"'"'WPPluginsOptions'"'"' ) )' {} + | xargs rm -f

Be careful with this command because it doesn't ask you before deleting files. You should test it in a safe place before running it in production.
