Look At Entire Column For Two Key Words

I have a work book with a lot of information. In column “W” I have a text comments, cells in this column probably have something or not, and the text is very variable. What I need is an instruction to look at entire column for two key words for example: "na co", "apna" or "apcredit" ... in case of one of these words its found I need the macro to make a process.

For example if in the column W there is any item (cells) with text "apnapo" then

First filter the information:

Selection.AutoFilter Field:=23, Criteria1:="=*apna*", Operator:=xlAnd
Range("K1").Select
ActiveCell.Offset(1, 0).Select
Do Until ActiveCell.EntireRow.Hidden = False
ActiveCell.Offset(1, 0).Select
Loop

Then write down something in columns K & L

ActiveCell.FormulaR1C1 = "Ion Apnapo"
ActiveCell.Offset(0, 1).FormulaR1C1 = "Pamela Elizondo"
Selection.Offset(0, -1).Select
Range(Selection, Selection.End(xlDown)).Select
Selection.Offset(0, 1).Select
Selection.FillDown..................................
