There a variety of ways to do this ... some will loop but I quite like to use the following method:

Public Sub RemoveAccount()
With Range(Cells(1, "B"), Cells(Rows.Count, "B").End(xlUp)).Offset(0, Columns.Count - 2)
    .FormulaR1C1 = "=IF(ISNUMBER(SEARCH(""Account"",RC2)),1,""x"")"
    .SpecialCells(xlCellTypeFormulas, xlNumbers).EntireRow.Delete
    .Clear
End With
End Sub
