I have been working on an issue with my Windows 7 PC here:
My PC is up-to-date with the latest Windows updates and generally well maintained. This PC has the Comcast Norton security Suite. The PC sits behind a ZyXEL USG40 "router" with various protection.
1.) After login on after a windows update ( I believe), I had no more network connection. Could not determine easy cause. Therefore, I rebooted. Afterwards the PC blue screened every time when booting up.
2.) I have been working on this thread with jwoods301 to get it to boot again.
However, several services do not start anymore. I believe the root cause is the workstation service that I can't start anymore.
"The Workstation service depends the following service: MRxSmb20. This service might not be installed.
I have executed additional steps such as sfc /scannow and tweaking.com repair.
The workstation service uses under logon tab the "Network Service" user account. Is this expected?
-> At this point I am trying to find out if my PC is infected or just in a bad state for unknown reason.
