VBA- Hide rows based on whether cell contains specific text

Looking to scan through a whole column to see if the product (in individual cell) may be discontinued. This is true if the word discontinued is in a cell. I want the whole row to be hidden if it is discontinued. Any suggestions?

Sub HideRows()
    Dim c As Range
    For Each c In Range("B3:B2452")
        If InStr(1, c, "Discontinued") Or InStr(1, c, "discontinued") Then
            c.EntireRow.Hidden = True
        End If
        Next
End Sub

Sub HideRows()

    Dim rCheck As Range
    Dim rHide As Range
    Dim rCheckCell As Range

    Set rCheck = ActiveWorkbook.ActiveSheet.Range("B3:B2452")
    rCheck.EntireRow.Hidden = False

    For Each rCheckCell In rCheck.Cells
        If InStr(1, rCheckCell, "Discontinued", vbTextCompare) > 0 Then
            If Not rHide Is Nothing Then Set rHide = Union(rHide, rCheckCell) Else Set rHide = rCheckCell
        End If
    Next rCheckCell

    If Not rHide Is Nothing Then rHide.EntireRow.Hidden = True

End Sub
