Title: AIS 5 vs. Windows Defender (Win7)
Post by: zekeblue on March 26, 2010, 10:41:26 PM
Should I disable Windows defender in Win7-64bit when running AIS.  Do they conflict at all or slow things down more?  I have disabled the Win Firewall.

Thanks.........

imo, yes u should disable defender.
conflicts can happen, also slowing of ur sys.

I got avast! Free here running Windows Defender. Never heard major conflict with the others versions of avast! too.

Let Windows Defender on. I never seen any 1 to turn off Windows Defender because of his anti virus or any problem.

even if it doesn't conflict with avast, it uses system resources. and u don't need it, when running avast, but as stated above - do as u like. :)

doesn't mean that r the only resources needed running/working it. ;)
u would have 2 monitor its behavior over time 2 get right results.
even the system slowing would not b logged anywhere, when defender and avast scan a file the same time or one after the other. but since u obviously r runnig a rather fast system.... seems 2 work ok 4 u! :)
but please don't 4get. there r older, slower systems out there...

I'm not running Windows 7, rather Windows XP SP3.  I have both avast! 5 Free and Windows Defender running with no conflicts at all.  Also, the memory usage of Windows Defender appears to be minimal at best.  If you are not experiencing any problems I would recommend that you leave Defender turned on.

I have never seen Windows Defender slow a system down or conflict with any Antivirus/Malware program using Vista or Windows 7. I never really played with WD installed on XP so I cant comment. Could WD cause slow downs and or a conflict, its possible? Why turn WD off unless you have problems. WD and Avast together should increase protection as WD monitors system changes Avast 5 does not. Also you double the malware protection.

My 2 cents

I turned off WD then installed ThreatFire, is better than WD and does not have any kind of conflict.

Thanks for the discussion everyone.  I guess it will come down to testing.  There may not be obvious conflicts, but I am interested in system responsiveness.  If I can't tell a difference, I'll leave it on.

Hate to disagree, but that advice strikes me as no more than mere opinion with no evidence of any sort of foundation to support it.

PC's are what I do for a living. The next time I see Windows Defender (which is built into Vista and 7) conflict with an anti-virus application will be the first.  If you can point to any reliable (not mere anecdote and supposition) evidence anywhere that this is an issue with WD and any well-made antivirus product from any reputable vendor, I'd like to see it.

My advice is to leave Windows Defender running.

WD is built in to Vista and 7 so avast! 5 disables the real-time scanning component when installed.

MSE does that - disable automatically and completely Defender - but I never noticed that Avast did, not even the real time scanning part. This said, Defender is completely useless when Avast is installed.

Well even in old pc or new pc i alway keep WD turned on without slow down or notice that its was conflict with avast! or anything else. ;)

On  XP SP3 that is true.

Windows Defender on Vista and Windows 7 is a completely different application than on XP.

Can you show some solid evidence of this? WD claims to be fully functional on my 2 Windows 7 boxes running Avast 5 Free.
If Avast 5 is disabling WD its doing it wrong because WD claims its functioning normally. It should not be disabiling WD anyway.
Avast 5 does not have some of the protection WD has.

This is Windows Defender on my Windows 7 system:
Client Version:  6.1.7600.16385
Engine Version: 1.1.5605.0
Antispyware definitions: 1.79.629.0

It is set to run a Quick scan daily at 7:00 AM.

I only remember a post (by Vlk I think) to the effect that because WD was integrated into Vista and 7, and had some useful functions, potentially conflicting WD actions would be suspended by avast! installation.

yeah, Vlk also said Ipsec would get deactivated if you disabled the firewall in Windows Seven ;)

I believe that is incorrect. And if I find out it is correct, I'll (with sadness) be saying goodbye to Avast.

Today I installed the latest build of TrueImage 2010 build 7046. Once completed windows defender popped up wanting to send files to MS to be analyzed.
So its BS that Avast 5 disables Defender. See screen shot.

I have the same client and engine versions though my definitions are not as up to date as yours. Is the link you posted for beta definitions because if I check for updates through WD it says I'm up to date. My definitions are 1.79.953.0 dated 4/1/10. I downloaded the 64 bit update and I received an error when trying to install it. It said to check to see which version of Defender is on my PC. I'm running Windows 7 Ult 64 bit. I would think Defender would be 64 bit by default?

Duh! I feel dumb now. I should have known. Works fine when you do it the correct way. So I take it that using this method gets you the latest definitions before they are available via windows update or the WD gui.

Don't feel dumb as it took me a long time to figure out why the Antispyware definitions: never matched the definitions on the portal.
