Completely Block Software From Internet

Hi all, I am trying to block software from connecting to the internet.
I have a backup image of my PC with it all working offline, but as soon as I connect it to the internet, the software connects.

It does this without opening/running the software, I think it has a background service or something that goes out on its own?

I have looked to try and see what is doing it to no avail, tried Glasswire to block it connecting but it still does it.

Can I find out the IP its connecting to and block that?

Just use the standard Windows Defender Firewall / Advanced options and create a new outbound rule to block all outgoing traffic from the program of interest

Thanks Steve, I have blocked it through windows firewall, it must have another service that connects but.

Which software, which processes do you suspect?

If you post more info we can try and help.

And here is a guide to create an Outbound rule in Windows Defender Firewall.

Edit: Oops, posted at almost the same time.

It's a cabinetry drafting program, my support has run out for 2017's version but I'd like to keep using it aswell as the current version we pay for.

Review the program in Task Manager to find what other programs / services it links to. Process Explorer gives more information https://docs.microsoft.com/en-us/sys...ocess-explorer

Hi there
don't forget also --your router also usually has a very good firewall - you can do all sorts of things on a router firewall and create user rules, block ports, slect inbound / outbound rules etc etc. The Router firewall is usually totally neglected by most people but is an excellent tool to safeguard your machine and can also give you logs of unauthorized attempts to access your machine.

router address is usually something like 192.168.0.1 or 192,168.x.1 or might be on an internal lan connected via a proxy something like10.0.0.x

just use a browser to the appropriate address and login. You'll find the firewall probably under things like security etc.

Sometimes mere DNS connection makes the software think, it is connected.
DNS is by default allowed for every software, since it is svchost.exe connecting.

You can monitor connections with LiveTcpUdpWatch

Thanks, how do you go about blocking the DNS for certain software?
