Thanks for that, LB. :) That copy/paste function in Command Prompt and PowerShell is a great new feature.

Just for info:

HTG Explains: I Have a Router, Do I Need a Firewall?

I’ll let MrE speak for himself, but he is correct and I do think the warning is at the least confusing. Perhaps it needs rewording. The router does indeed need access to the Net. It should have a firewall as explained in the article I posted. Then, the way I understand it, your ISP has a router that your router is connected to that has a firewall, therefore not everyone should have access to your router, save your ISP, which should be trusted. E.g. If you don’t pay your bill, they’ll unplug your router or disable it or they could temporarily disable all or some routers on the system for maintenance. Your ISP can’t get to your device because of a system firewall or at least they shouldn’t be able to.

So far as your 10TP system is concerned; I’ll assume it was configured as a part of your home network that’s why the warning from Avast? Dunno. I would reconfigure that not to be in Home Group. Since Avast can’t be loaded I’m quite sure Defender is sufficient. I wouldn’t and don’t keep personally-sensitive files on my 10TP.

I think I have finally solved this problem, the guilty party Microsoft.
A condition for installing W10 preview is being able to control the transmission of data. See link below.
To do so would mean they would be able to bypass the normal security inbuilt by the ISP router.
If you read the conditions below you will notice that the only way to stop this is by removing W10 completely from the computer affected.
How did other household computers get compromised, Cloud connection meant data transfer.
My ISP strongly recommend denying access to outside access, although they do give the option such as for example allowing Microsoft access if one so wishes.
http://go.microsoft.com/fwlink/?LinkId=400912
Suggestions that this is a W10 versus Avast thread is absurd, I am only interested in maintaining security on all other computers in my household which have not got W10 installed yet operate from the same modem safely.

MS doesn't have any control over your Router. You made the change based on Avast's alert - what did Avast say about it?

If your ISP said lock down your router, undo the change(s) you made following Avast's alert.

The Win10 agreement basically says
"Microsoft will collect more information about your system than usual so that we can analyze Windows 10 behavior and faults."

It doesn't say "Microsoft will open your network" You are the admin of your network, how it is configured determines a lot as to how hard the network is to penetration.

You decided to install the Windows 10 Technical Preview. If you're not comfortable with early and most likely buggy code, then you probably shouldn't be playing in this sandbox.

If you posted screen shots or information on what you changed rather than the recommendation to change or the resulting scan after the change - that might help people understand.

The Avast pic in post#1 clearly states router in a few places - what no one knows is what you changed and where you changed it.

That warning makes no sense. Of course your router is accessible from the internet. How else would the internet work? Your router *IS* what gives access to the internet... computers are reporting it.

What you should have said is "your router has access to the internet" NOT "your router is accessible from the internet".

No. Because that's not true.

Your router *IS* accessible from the internet. I don't care what Avast is telling you. It is. If it wasn't, YOU could not access the internet. The problem is that this does not tell the whole story. Simply being accessible from the internet is not a problem. Having your router forward data without explicit instructions to do so, is what's a problem. That, however, is too difficult of a concept for Avast to explain to someone who doesn't understand how the internet works.

Whenever you connect to something on the internet, your router opens up ports on its firewall to allow that access. Otherwise, there would be no way for you to receive data back.

Your limited knowledge of how routers work leads you to accept what programs designed for non-technical people say at face value, but they are just hiding the technical details from you.

Demeaning statements such as your last sentence are based on conceit. Beware the wise man in his conceit, he is worse than a fool. Proverbs.
All this nonsense concerning Avast "all it did was to warn", if you read my earlier posts by clicking on a link brought me to my ISP router configuration page where I RECONFIGURED IT.
Avast was installed a month prior to my W10 install and all computers had been checked for home network security and passed before the W10 install, only after was the change observed.
As for security Microsoft have the ability to access all your private and personal details on your computer in W10.
Something that even you cannot do.

It's not meant to be demeaning. Some words have become negative, but when used in context are not. You have limited knowledge. That much is clear from your writing. I could have used the word "ignorance" as well, both just communicate a fact, not an insult.

All of us are ignorant about something, or lack knowledge about something. That's not insulting. I'm ignorant of most chemistry, that doesn't make me stupid.

That's not what you said. You said you fixed it "By clicking on "disable access to your router from internet" under the word Solution" and then, as per the rest of your comments, neglected to give any additional information that might have actually been useful in stating what you actually did. You said nothing about going to your router configuration page, or that you reconfigured it. The implication was that Avast fixed the problem.

You're not listening. The feature that displays that error was introduced by Avast in the 2015 version, which was released on October 30th (a little over a week ago). It did not exist in Avast previously. Therefore, it would have never given you that warning a month ago, because Avast was incapable of doing that scan at that time.

Here's a blog entry from Avast that describes it:

https://blog.avast.com/2014/11/04/av...rity-scanning/

Here's an announcement of the release:

Avast 2015 Final Version Released | getavast.net

Why do you seem so intent on blaming Windows 10 for this problem? Why can't you seem to understand the nature of the coincidence of the new scan being introduced at the same time?

I've repeatedly said, the problem here is that Avast is too vague in its messages, but point in fact.. you're also incredibly vague in describing what you've done, and what you changed.

Getting back to the original question:

dencal said:

Have the latest version Windows 10 Preview 6860.
The only security feature installed is the inbuilt Defender.
Other computers in my house are all W8 or W8.1 PRO.

All other computers have Avast free installed, and with the latest 2015 year version comes a Network Safety Checker.

This warns me that my router is accessible from the internet on all other computers in the house.

Q1: Is this due to my W10 installation and the fact that Windows need access to my computer ?

Q2: And does this compromise the safety of all other computers in the house which all use the same router.

Q3: Can all the other computers be safeguarded, and how ?

All answers come with a few questions.

A1: This comes from a new feature in Avast. Let me say this; I used Avast for a long time and there are usually some fairly ugly bugs in early releases of new versions. It settles down after about two weeks and works well ... but yes Avast can be buggy. The fact that Avast gave you access to your router bothers me more than the the new scan result.

If I knew what parameter you changed, I or another member might be able to offer some advice. If you're too security concerned to provide details, then I'm afraid members won't be able to provide much help.

We know that you

have computers (how many?) that are running Win8 or 8.1
have one computer running Win10 bld 9860 (physical or virtual machine?)
the computers are networked (router, switch ??)
have an ISP (which one??)
have Avast 2015 (on all machines??)
Reacted to the results of a new Avast scan (which machine reported it Win10, one of the others?)
Clicked the "router" button
Changed some setting on the router (which setting?)
Ran the Avast scan again and got the all clear signal from Avast.

A2: No, although how the router and machines are configured with regards to the network does.

A3 Yes, it depends on configuring your network with high security and protections.

If you want help with network configuration, then post your network information on your thread. We're blind on this side.

On the Win10 machine, create a file showing how that machine is configured for IP.
Open a standard Command Prompt and type:

ipconfig /all > ipAll.txt
exit

Attach the ipAll.txt file form your User folder to a new post.
Please identify the router make and model and
please state what configuration parameter your changed
