fake? untangle preventing acces to any sites

[birdsassy]

Somehow untangle (fake?) got on my network. Now none of the computers are allowed to acces any sites. Any ideas on where to start? Have tried all network securtity options including on the router, has not made any difference. This is happening an 2 Window 7 computers and 1 Windows 10. Thanks for any ideas.

Untangle (the legit kind) is an entire firewall dedicated operating system...; it is not merely an application/program, ...but, it is possible someone put it in a VM, and put that PC in a gateway position before the router's WAN port? INvestigate your wiring, and , it might help if you provide few details. (internet connection, router, switches, if any., etc)

But, as you suspect it is fake, I suspect you turn off all PCs on the network, and start with an uninfected PC or laptop connected to your router to determine if it is working.
