Windows Defender for XP Pro.

by Mailman / December 18, 2009 11:51 AM PST

I have downloaded the installer for Windows Defender. But when trying to install, I get the following message:

"Microsoft Client Protection has been found. Please remove that product and rerun setup."

I have no idea what that means. Is there any way for me to install this program? I'm using Microsoft Security Essentials for my anit-virus.

..., the reason I was wondering is that I had Windows Defender and Avast running for quite a while. Then Avast started giving me way too many false alerts, and even prevented some programs from installing with false virus alerts.

So, I uninstalled Avast, and went to MSE. MSE installed just fine with WD. The only thing was that WD would not run a scan automatically. But I could run it manually.

I became aware of a newer version of WD, so I downloaded that one. During installation, it said I had to first uninstall the previous version. So I did that. Then the new version of WD would not install, giving me the message in my first post here.

So, I guess MSE is the only thing I need for all around protection?

Thanks again,

MSE seems a good replacement for anti-virus and other anti-malware scanners, including Windows Defender, and the reviews I have seen are very reasonable.

It is not a firewall, so you will still need one of those, either Windows own firewall enabled, or a 3rd party one.

Not all scanners find everything though, and in particular with spyware, you could use something like Malwarebytes' Anti-malware, or SUPERAntispyware, or both, to complement MSE. They are both free, but the free versions do not allow you to use the resident scanners, meaning they will not load in the background. But that is fine, they can be used as manual scanners, once a week or so.

MSE replaced Windows Defender, so that is why you don't need WD.

.....I have downloaded both of those to run manually. Thanks again for all the help.
