Support NeoGAF

[ShogunDarius]

Just had a weird issue out of nowhere where defender and Kaspersky seemed to be conflicting with each other, as win 10 notifications kept saying they were both off. The really weird thing is when I loaded up either defender or Kaspersky they both said they were on and I was protected (defender needed an update).

Anyone else seen this? Do you know the cause? Or a proper solution?

Disable the Windows Defender? It shouldn't be enabled when a third-party antivirus software is installed, I am surprised neither Kaspersky installer nor Windows disabled it.

 

[Stevey]

Yeah, you only need one AV running at once.

I did, it still happens, it then complains that defender is in snooze mode while Kaspersky is off when it really isn't.


Thing is when I first installed Kaspersky it was fine with win 10 just 2 weeks later this happens out of nowhere

It's not uncommon as AV programs utilize kernel mode and filter drivers, and can come into conflict because of it - particularly around network interfaces and disks (logical and in regards to the actual device drivers). Commonly, they'll disable whatever they're conflicting with - in this case the other AV.

Vendors will often have workarounds for such scenarios, but it takes digging through their support literature to find it. I recommend choosing one solution and sticking to it.

What version of Kaspersky exactly? Maybe it's outdated and has trouble with W10.

I find it strange that W10 Defender didn't disable itself with Kaspersky.. I know mine shut off when I put Avast on.

Have you tried taking all of the steps Microsoft recommends for disabling Windows Defender, and then setting the service (WinDefend) to 'Disabled'?

Do you have a link to that so I can double check?

 

[RazorbackDB]

I recommed the .reg file here, it will disable Windows Defender and prevent it from enabling itself again.

 

[Jackpot]

You shouldn't have Defender and another AV running at the same time. Bad practice.

 

[DonMigs85]

Strange because when I installed Avast it automatically became the default AV and Windows Defender became dormant.

I didn't readily find a MS TID but here's some article form 2014 that still appears relevant: http://www.howtogeek.com/howto/1578...emove-windows-defender.-also-how-turn-it-off/

Yeah I just had this happen to me with bitdefender. Says my firewall is off when it isn't.

Yeah Ive heard this has happened with a few 3rd party AV

 

[ShogunDarius]

ok this just started happening again. one difference though, defender isnt actually on this time i turned it off and all the defender buttons are greyed out

It's the other way around. You shouldn't be installing third-party antivirus in the first place, because Windows Defender is all you need.

This is absolute bullshit. Windows Defender is consistently worse than alternative AV software. Your advice is like saying "you shouldn't be installing Chrome/Firefox/whatever. Edge is all you need".

And for the record I've had this nonsense happen to me with multiple different third party AV products. I used the local security policy toggle (Microsoft approved because it's their security policy) to stop it from interfering.

You were so close, but nope at the last part.

Don't fuck with service configurations. Just don't. Windows Defender is built to disable itself automatically when it detects other AV software running instead. If you disable the entire Defender service, then the pieces it needs to run to check whether other AV is running won't operate properly, possibly resulting in other Windows components not knowing how to behave.

Defender is also built to re-enable itself in case Kaspersky or other software stops working for whatever reason. For for shit like Norton and McAffe which still require subscriptions, Defender will enable itself if your subscriptions run out.

Leave the service as is. Just follow Microsoft's recommendations. For AV software you don't want to mess with this stuff.

I recommed the .reg file nope, it will disable Windows Defender and prevent it from enabling itself again.

No no no. Stop running random files recommended by no-nothing "expert" sites. There are fully supported and well-documented ways explicitly created by Microsoft to configure things in the right way. Not only is it utterly reckless to run a random registry file from some random web site, you're probably leaving your PC in a completely unsupported state that will just get more and more broken all the time.

Sure, maybe right now everything appears to be working "fine", but one, two, five years down the line? Microsoft only tests software in supported configurations, and if you start making random unsupported changes, you're bound to screw something up in the long run once future updates are installed which don't understand or expect to see whatever changes you made years ago.



This stuff doesn't need to be complicated. Just use it as it's intended to be used. Disable it in the way it's meant to be disabled. If it's broken right now, find a way to fix it in a way supported by Microsoft. Your future self is already thanking you.

At least it doesn't make you vulnerable to having your system rooted by an attacker who sends you an email that you dont' even open.

No it just leaves you vulnerable to a whole heap of other stuff because they're lagging behind their competitors all the time.

It doesn't leave me vulnerable to that stuff, because I don't download random stuff from torrents, click on links I'm unfamiliar with, go to sketchy websites, or enable ads.

 

[Sinfamy]

I'm running Bitdefender 2014 + Malwarebytes on Windows 7 with automatic updates disabled.
I've also got outdated versions of Java, Adobe Acrobat and Flash installed.
Come at me.

 

[Auctopus]

When working on/fixing other computers in the past, both Kaspersky and Avast have requested that I delete Windows Defender as it may be potentially harmful. I don't really trust them because of that.

Defender + Malwarebytes Scans.

Hi, people running the botnet Sinfamy's PC belongs to! How you doing, pls don't DDOS something I like.

With many recent security holes you didn't need to do anything unusual to get infected. Hope you've got noscript or something similar alongside your adblocker or you're operating with a false sense of security.

Windows Defender was ridiculously slow on blocking many ransomware exploits. I know they've made improvements recently but my trust in Microsoft to protect my computer is basically zero at this point.
