Got messages that McAfee detected zeroaccess & artimis & confined them. But got all the symptoms including loss of internet access and other functionality.
Ran McAfee twice - in regular mode & safe mode. It didn't find anything.
ms.exe detected by other software I found.
Believe zeroaccess disabled mcafee. I found it on my machine but settings were changed & I could not delete it myself.
Your software needs to be updated to detect these newer viruses.
Also, prefer you delete it entirely, not just confine it.
