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.
3. I don't know if this is just a case of not detecting you router correctly. As it is reporting 'WEAK_PASS' I don't think that wouldn't really be directly related to incorrectly detecting the router.
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?
