Hi there
Why on earth do people always start at the most complicated places from which to solve problems !!!!
Why not first start with your ROUTER - look at its logs - you should see inbound logon requests -- the router also can give you a HUGE better set of security than Windows firewalls etc (although of course don't disable the firewall).
To get access to most domestic routers logon to typically 192.168.0.1 (the 0 could often be replaced by 1 or 2) - check the router literature for the exact configuration. Some cable routers also require a pin number at logon - usually these will be stuck on to the bottom of the router / cable box.
For starters if you have known sets of PC's restrict the Internet usage by MACID -- any even half decent router should be able to do that.
From there you should be able to tell if you've got any open ports etc -- then block those.
Once you've isolated the router you should then look at the Windows system to see where "Ingress" is occurring -.
Teamviewer IMO isn't worth it -- if you can run Linux there's so many ways of securing it - I won't start here other than suggest you could make a Linux server act as your Internet gateway. Plenty of info on Linux Forums for that topic. Simply set up the gateway and on Windows machines set the browsers Internet settings to use a "proxy server" i.e your gateway. There's a zillion ways and options here so it depends on what you want from a full blown secure VPN server to something a bit more basic than standard windows with a lot more security in it.
Install package XRDP on it if you have a Linux system with a GUI - that way standard RDP from Windows will access your Linux system identically to the way you can RDP to another windows system.
SSH on Linux systems is also a good idea too.
