clear the row data if it matches

Hi,
I am looking for a macro that will do the things mentioned below

If column E & column C of sheet3 of 3.xlsm matches with sheet4 of Column B & column D of 10.xlsx then match column E of sheet3 of 3.xlsm with column B of sheet1 of 3.xlsm & if matches then clear the data in sheet1 of 3.xlsm

Macro will be placed in 3.xlsm file So the path should be hardcoded in the macro, so that i can change it as per my needs
Note: we have to clear the data from column C, we will not do anything with column A & Column B of sheet1 of 3.xlsm
sheet name can be anything



Thnx Alot
