Select each row one by one and check for a substring in each cell of it

Hello,

I wanted to check for a substring (say "Good morning") in every cell of each row starting from a particular column (say C till E) one by one and, at the first instance of finding that substring in any cell it should remove that row completely and proceed to the next row and repeat the same thing till all the rows are exhausted.

I hope I did not confuse it.
Thank you for the help.
