Windows Defender is an anti-spyware tool intended to supplement your anti-virus program. Although it uses the same name, the new Windows Defender on Windows 8 is not the same as Defender in previous operating systems. Windows Defender on Windows 8 is not the same as Windows Defender on earlier operating systems. You can use the original Windows Defender alongside avast on Windows 7. Regardless of that, is it safe to run that real-time protection and leave auto-scan on while running avast! Free (or any resident anti-virus for that matter)? And if it's safe, is there any real need to run it? (I also use Malwarebytes, but not as a resident program.)Įdited by PamJ55, 24 November 2013 - 11:49 PM. What exactly in the Windows Defender that runs on Windows 7? I've read that it's an anti-spam thing, not anti-virus. Since I was familar with this great site here and someone over there referenced a thread on this subject here (from 2009), thought I'd ask you good folks since that 2009 thread is so old.

At present, there seems to be a difference of opinion on the answer. I posted over on avast! forums asking if these are two things that could run together or not.

Not knowing exactly what this was and knowing you should not run two anti-virus resident programs at the same time, I turned off Defender real-time protection and the auto scan. Shortly after, I realized that something called Windows Defender was also running. I just purchased a Dell computer with Windows 7.
