Look at network connections
As you are all reporting problems when internet is connected it might be worth running CrowdStrike. It's a portable tool that checks your network connections against WOT and VirusTotal and highlight anything suspicious or dangerous. If you want to run it you can get it here:
Community Tools | CrowdStrike - scroll down the page to CrowdInspect
If you choose "Run as Admin" when running the executable then toggle "Show full path" see if anything shows up for explorer. If it does - make a note of the ip address and DNS server.
Also toggle the Live/ History button so see current and past connections during the CrowdInspect session.
