Hello,
everytime I start my W10 machine, Avast is deactivated by Defender!
What can I do (see screenshots [b]after Avast virus update[/b])? As you can see in my second screenshot: Avast is set to 'automatic', but why didn't start? Another question: what will happen, if I start Avast via services? You can't deactivate Defender in W10 via services! ???So, if anybody has a hint, answer please.
=Snake=
This should work the other way around, defender should deactivate with Avast installed. Which Avast product did you install? Please see Asyn’s questions above to give us some more information
1: Free
2: 2015.10.4.2233
3: See my sig and screenshot.
4: See my sig.
5: Can’t remember, I started using Avast Free ~1994.
Any reason for still being on a 10.4 release of avast? I am sure this is one possibility of why Defender inst correctly detecting Avast and disabling itself. Would it be possible for you to update to the current release, or at least to the 18.x branch which is also still supported?
1: Yes, for Avast newer versions are not able (caused by nw scans) to recognize my router right.
Therefore I rolled back to this version.
Before that I got error messages like ‘your router isn’t configuered right’, ‘WEAK_PASS’ or ‘ftp error’.
2: According to the reasons: NO!
1: If you had the latest avast 19.3 version for those systems on win7 or higher (assuming that the CPUs support the SSE2 instruction set).
The XP SP3 systems in theory should be able to run version 18.8.xxxx (on my XP Pro SP3 I have avast! free 18.5.2342 (as I had problems with 18.6 and above). They too would also require the CPUs support the SSE2 instruction set.
EDIT Final point:
Do you get these network errors after running a scan ?
I would o a custom install and don’t install the WiFi Inspector if that is what is causing the router/network detection/errors.
Hi David!
All that I tried several months before and I have cpus with and without SSE2 support.
That certainly puts a crimp in what you are able to do, version wise.
I made an edit on my last post, I don’t know if you saw that, just trying to find when you get these errors and see if there is a way round that.
Do you get these network errors after running a scan ?
I would do a custom install and don’t install/uninstall the WiFi Inspector (if that is even in 10.4) if that is what is causing the router/network detection/errors.
1: Could you write that with other words, please?
2: I did.
3: Yes. Whenever the wifi Inspector was involved and several times I tried to push the Devs to correct it.
4: As you know, I have several machines with several os from XP to W10 and I had several Avast
versions from 18.5, 18.8 to 19.1 and all they showed me the first two errors. During my try to test
19.3. beta I got the third error message with the ‘ftp’ error, but my router has no ‘ftp’ section!
So I gave up treating the Devs to the right direction.
Since a lot of years I only do custom installs and so I rolled back to 10.4.2233 for it’s the only one,
which recognized my router right, so I got no error messages.
Only one machine with XP and W7 is on another flat and without SSE2 support. All machines without any special notice (e.g. x64) are x86.

1: Crimp = Makes it very difficult with the different mix of systems with XP CPUs that don’t support SSE2 instruction set. They are pretty much going to be stuck on the old 10.4 version of Avast.
The weak password could be one of a few things, it is truly weak, very short or in some cases the default password (Admin Password) that you get when first got it and hasn’t been changed. It could also be that the Encryption level used on the WiFi router older models had a weaker encryption level I think WPA2 would only be on newer WiFi routers. See https://routersecurity.org/ for more general information.
I’m not sure if the ftp error is router related as ftp (File Transfer Protocol) I would say is OS related. Though on my XP Pro SP3 system I haven’t experienced this error.
Unfortunately with old versions of Avast coupled with, old unsupported OS versions, I don’t believe the Devs would be spending time on it. That may not be their decision as any retrospective fixes on old/unsupported versions would have to be authorised higher up the chain of management.
4: I’m not sure there is anything else I can add here that hasn’t been covered.
To 1: Thanks for your explanation. As you can see in my sig, if you have a machine with no SSE2
support, all other sw has to be hold on lower level.
To 3: Concerning my router: when we changed our home at the end og 2016, I had to change my
internet provider, too, for they didn’t support DSL anymore.
Then I got a new simple router with WPA2, which works fine until Avast told me such nonsense.
I think, it was a W10 machine, that brought the ‘ftp’ error and in the meantime I installed W8.1
on one of them. So I have only 1, which has no CD/DVD recorder, but big SSD hd.
To 4: I would ask you about trying to start Avast via services. What do you think? I’m not sure , if Avast
will deactivate one of the 2 Defender av-tools (see my first screenshot) or will the manual start of
Avast fail?
Edit:tipo
What’s the reason for running 2 AV tools at the same time?
When you run an outdated version of a third party AV, you receive a warning from Defender.
It’s quite possible that the version of Avast that you are using isn’t accepted as valid protection and Defender
simply takes over. It’s similar to not having another Av present on your system.
I didn’t receive any warning from Defender. So I’ll try starting Avast manually via services and see, what happens.
3: Routers are a bit weird as many are branded or made for a company based on the infrastructure of a different brand. Avast often finds things like this and to all intents and purposes it looks like avast has got it wrong. But that is somewhat hard to tell for sure. However the underlying errors/notices you got (‘your router isn’t configured right’, ‘WEAK_PASS’) could very well be correct.
I’m still unsure that the ftp error is directly related to your router and avast. I don’t know when this ftp error came up, but ftp is usually used via your browser, like the instances where avast users are asked to upload information to the avast ftp location. Otherwise I can’t see when it would be used.
I don’t know if this might be used by avast for some updates, VPS, streaming updates, etc. Unfortunately I don’t know exactly what the WiFi check included in the scan, but I have my doubts if would be checking ftp.
4: The problem is that it is Windows itself that does the deactivation/activation of Windows Defender. When you install a third party antivirus the Windows Defender Security Centre (I hate this name as I think it misleading), handles this not the AV. The Windows Defender Security Centre should show details of the installed antivirus, mine shows no action required and I have Avast Antivirus installed.
Below this is a Windows Defender Antivirus options, in mine I have turned the periodic scanning off for Windows Defender Antivirus. Other than these periodic scans defender should be passive (not active).
I haven’t experienced any issues with the win10 Windows Defender Security Centre antivirus control.
To 3: I’m quite sure, that I installed a very safe PW on my router. Therefore I don’t trust Avast in that
case.
My experiences concerning Avast scans are not small and for a long time I was Beta tester
(as HDW38 and =Snake=), too. You can proof that.
To 4: Where can you turn off or deactivate the periodic scanning of WDA??? I didn’t find anything.
Maybe it’s, cause I don’t like it.
BTW: As I moved the W10 mouse half an hour ago, I saw a wide blue screen (not black) without any
icon or so and moving or clicking the mouse didn’t change anything! So I cut it off (electricity) and
started new. Why and what happened in the meantime (a periodic scan)?
After that, I could work as usual.
Edit: But I missed the Avast icon at the right side of the taskbar!
Working as usual was a bit far away, for first of all, I had to ‘repair’ Avast (see screenshots [German]).
3: As I mentioned Weak Password could be more than the one you set, routers come with a default admin password, you can search the internet to actually find these admin passwords for the various router models. So if the default admin password is still present, it is a weakness.
4: If you found the Windows Defender Security Centre > Virus & Threat Protection Antivirus, your pretty much there. It should show the antivirus that is installed, Avast Should be listed and No Action needed (in my case as it is running). Does your show avast is installed and no action required ?
You could well have some other information if Avast isn’t running (and Defender Antivirus is) or is out of date ?
As in my attached image there is a Windows Defender Antivirus Options and a down arrow to expand, that is where I found it. However if Windows Defender Antivirus is actually running, active not passive, I don’t know if there would be any option to stop periodic options.
On BTW: occasionally I have an issue with the mouse (it just stops moving) on my XP system, sometimes that is down to low resources, but that does recover. I haven’t experienced this on my win10 laptop.
Does your keyboard still work when experiencing this ?
If so try the three finger salute Ctrl+Alt+Del keys at the same time this brings up your Task Manager. This could give indicate if you have a resource issue, etc. and it should allow you to restart or shutdown. Doing a hard shutdown, electrical power off could well crash some programs (and possibly corrupt some running files), possibly why the avast tray icon wasn’t there.
Note, I just wonder if you haven’t got anything else going on with all these different issues (what that might be is the question).
To 4: I’ve some more screenshots of my W10 laptop. I guess, the first one will answer your question.
Is the second one of interest for you?
To 5: Sorry, but I couldn’t see any image. ???
The third screenshot shows my W10 desktop. I like it.
