Sometimes network driver is deleted
Lately, I have this problem. I have a red sign on the network icon and the pc cant connect to the internet and the network driver is missing. If I install the driver and restart the pc, then the driver is found and the pc can connect to the internet. If I shut down the pc and restart the red icon appears again and cant connect to the internet.
'What can the problem be?Hardware or a virus?
Any help is appreciated!
