Yesterday my son's PC started refusing to connect to the internet. He has both ethernet and wireless, and both systems are fully working on other machines. The error message in Chrome is "DNS probe finished no internet." Under network settings the ethernet is labeled unidentified, limited and wireless says connected, connection is limited.
I tried to do a system restore but that function is turned off and grayed out so it can't be turned on. Figured he had some kind of infection. AVG didn't show one, Malwarebytes only showed two PUPs. Adwcleaner was clear. Combo fix wouldn't run and Junkware removal tool starts scanning and freezes.
I used the netsh command in admin mode to reset winsock and ip. Winsock reset failed, said the file was missing. ip reset had no effect.
Any suggestions would be appreciated!
