It started about the first week of September. My symptoms were, no program that connects to the internet would work, yet other programs would. when you click on the network icon in the bottom right corner nothing would happen. System restore would not work, MS security realtime would be turned off and could not be turned on and any other virus programs would not start. System restore would only work in safe mode and there was always a critical update in there even though I have never check for updates selected. When I would restore it would come back the next time the computer was turned on. I reformatted and reinstalled everything and it came back about a week later. I reformatted and reinstalled everything again and about a week or it came back. I scanned my system with every virus program there is and they found nothing, And I am sure it is a virus. After many hours I have figured out how to control it, but I can't get rid of it. What I have found out about it is that it must be in some program that I use, but I have used them for a long time and have not installed any new ones, but they have been updated. It is some kind of virus that has been there for a while and at a certain time it will activate. It installs it self as a critical update in system restore then when it activates it seems to control every program that is connected to the internet. The way to control it is to put a system restore shortcut on the desktop and check it several times a day. As soon as it appears right click computer, properties, advanced system settings, system protection, configure, and delete all restore points the make a new restore point. On the C drive in system volume information if you check there will be a file there that that occurs at the same time and I think that is where it is hiding. It appears randomly, but at least if I do this I can use my computer till I figure how to get rid if it. Long post but that is the info I have on it.
