I installed the free antivirus and when going through the services I was trying to lock down the extra “fluff” (OEM Proprietary stuff) and after rebooting it will no longer give me a login screen
I see the windows flag and afterwards just a black screen that sits there.
Try booting in Windows Safe Mode and restore what you changed. To get to Safe Mode start tapping the F8 button towards the end of the BIOS until you see a screen with boot options. Choose Safe Mode.
If you are in Recovery Console you can try to set the “Comodo Internet Security Helper Service” to disabled.
That should allow booting in to Safe-Mode again…
