Hi,

is KIS 2012 compatible with Windows Defender? Is there any problem with having both running, or should I stop Windows Defender? If I should, how can I do that? I searched inside Windows Defender's options and I did not find any option to turn it off. :c

Thanks. Regards.

Hi,

Definitely turn Windows Defender off.

Computer>C:>Program Files>Windows Defender>>MSASCui>Tools>Options>Uncheck Real-time protection and Automatic Scanning.

Reboot

I definitely should have searched before opening this thread. :c My bad.

Thank you but instead I followed what written here: http://forum.kaspersky.com/index.php?showt...indows+defender, basically: "Deselect the Use Windows Defender box and press the Save button.". This is ok too, correct?

Also, I won't be less protected, will I?

Same results. Both disable Windows Defender.

Also, I believe running Windows Defender at the same time as Kaspersky gives less protection. Similar programs using the same resources causes conflicts between the two.

I actually have never had problems in having both running, but I disabled it. If anyone (mod/user) thinks Windows Defender and KIS work fine together (I actually doubt it, the first thing one learns is "two or more AVs running at the same time conflict"), please tell me.

I use Windows Defender with KIS and have been doing so for 2 1/2 years without any issues. I have read many books and articles from respected security analysts that have commented on whether you should run 2 or more AV/Spyware/Malware scanners on a PC. The reaction is always mixed, some say it offers extra layers of protection, others say they can cause conflicts or reduce system performance so much the benefits are outweighed by the cost. If you look at Windows defender it has 2 main scanning components a real time component and an on demand scan component. The real time component (often referred to as pro-active scanning) constantly scans the behaviour of unrecognised processes and tries to intercept any potentially dangerous interactions with the system or other processes and files. KIS also has this component. This is where problems theoretically could manifest as both are trying to do the same function. The other component is on demand scanning (also called re-active scanning) which is a scan of the files in memory and on any system drives using primarily a signature or checksum of the file and comparing that with a database of known virus, malware, spyware, etc. The only issues with reactive scanning is that if both software try to scan the same drive at the same time this will greatly reduce system speed and increase scanning times. On the other hand if you were to only run Windows Defender occasionally and temporarily suspend KIS on demand scanning (scheduled scans are also on demand scans) there should be no conflicts or reduction in system performance. So my recommendation is to disable real-time scanning (in the options) of Windows Defender and make sure there are no scheduled scans set. As an afterthought about Kaspersky's policy regarding Windows Defender. It is easy for them to deactivate Windows Defender (many other security suites do) on install yet the do not. Also in my experience of installing Kaspersy, it usually kicks up a fuss when it detects any security related software on my system and yet it ignores Windows Defender even though Kaspersky knows it is enabled by default on Vista and Win 7 systems. So I hope that helps, or maybe it muddies the water a little bit more. b_lol1.gif

my educated response is to always disable windows defender. it does conflict if left on in default configuration.

for example, one stability issue due to running both is that scans run in KAV/KIS can lock up and not complete when defender is enabled. i have seen this posted many times on here and managed to recreate it myself while experimenting with different setups.

disabling realtime protection in defender may help but then it may as well be turned off completely because it really isn't that great at detecting malware anyhow. in its place as an on demand scanner i recommend the free version of malwarebytes antimalware for a second opinion scanner if you feel the need for one.

apart from that CPU and memory usage increase due to both applications trying to check the same files at once. it really isn't worth the hassle of leaving defender enabled.

Hello,

Launch "msconfig" and disable WD in Start-up and Services.

I would agree that the real time scanning component of KIS is far more sophisticated and effective than Windows Defender. I also agree that Malwarebytes' offering is superior at malware (particularly trojan) detection than Windows Defender. Microsoft bought the source engine of Windows Defender in 2004, from Giant Software Company. It was then known as Giant Anti-Spyware and is a Spyware scanner not a virus or malware scanner. Which is why Windows Security Centre recommends the installation of anti-virus software even when Windows Defender is enabled. My personal experience with using both software (even with Windows Defenders Real Time protection enabled) as not revealed any conflict or system issues (so far!). No two PC systems are exactly the same so I accept that others might have issues with running both. On the other hand, in the 2 1/2 years that I have used both together Windows Defender only identified and blocked one potential threat. And then I am not entirely sure that the threat was that serious. IMO KIS is a very effective security solution and Windows Defender a good Anti-Spyware product. Does anyone really need to run another scanner along side KIS? Well ultimately I think that depends on how paranoid they are! b_lol1.gif

I must say that after disabling windows defender Kaspersky is launching really faster at the startup... before it took like 1 minute to start, but now it starts right when I turn my computer on. tongue.gif

1) I don't see Defender in either Startup or Services. Perhaps it was removed when I edited the Defender settings?

2) I notice Windows Firewall is enabled in Services. Should I disable this?

Thanks,
Chris

Start > In the box, type "Services.msc" without the " ". Scroll down to Windows Firewall Service and Windows Defender Service and double click and change the start up type to disabled for both.

There should be no need to disable the Windows Firewall service. All this will accomplish is to prevent Windows Firewall to enable itself if and when Kaspersky is uninstalled or crashes. Having the firewall services and the firewall itself disabled is both possible and preferred.

Not many people know there is a separate switch and take the hard approach.
