Windows Defender obsolete

Solved
Hello,

I’m discovering today that W. Defender is obsolete on my PC (Vista). Until now it was OK.

Updates are not happening.
Which software to choose as a replacement, or how to re-enable Windows Defender, offered with XP Pro, but I can’t find for Vista?

Thank you for helping me, once again

Configuration: Windows Vista Internet Explorer 7.0
