file_list.csv is the csv file.
log.txt be the above mentioned file

Code:
file_list=`sed 's\,\ \g' file_list.csv
for file in $file_list
do
   grep -q $file log.txt
   if [ $? -eq 0 ]
   then
         printf "*%s",$file
   else
         printf "%s",$file
   fi
done >new_file_list.csv

I have used just grep to see whether the file has changed or not.
