Vista 32 bit, Windows Defender on or off?

[Roger]

Heard quite a few people switch it off. Is it a cpu hog?

Turn Windows Defender on or off


When Windows Defender is on, you will be alerted when spyware and other potentially unwanted software tries to install itself, run on your computer, or change important Windows settings. If you use the default settings, Windows Defender will also check for new definitions, regularly scan for spyware and other potentially unwanted software, and automatically remove any detected item that has a recommended removal action.


Mine is off becauze I use Norton Internet Security - if your not using some otheer security I'd leave it on.

Yes. On if you don't use a third-party offering. Off, otherwise.
