windows defender and avast 5

Hi all,

Recently windows defender stopped working, coincidentally around the time I installed avast version 5. Can somebody tell me if avast negates WD or is it something else? Thanks for any help

Ive used WD with avast before, have a friend that still does, never conflicted.

No. avast is fully compatible with WD.

no conflict but unneeded. Avast is an (almost) full anti-spyware solution. Only exception is the lack of registry protection (not watching and not scanning either, what Defender does).
I did some test a while ago with Avast:

(can’t tell how relevant SpyCar is, I mainly did it for fun…)

Many thanks for the replies,

I have had a problem with WD so doing a format/reinstall.

I keep Windows Defender updated through its portal:

Get the latest definitions
Latest definition version: 1.81.209.0

Download then run the 32-bit or 64-bit update for your system:

I had Avast 4, Windows Defender, Spybot S&D, and SpywareBlaster all together worked Awesome But in my own opinion Windows Defender didn’t do much so I got rid of it…
