Around a week ago as I closed the computer down one evening, there was a MS update running, I allowed the update and the computer shut down.
The next morning my laptop would not start up. It would load to the password login screen and no further. I was able to go into safe mode and run system restore and this would then allow me to use the computer as normal, I was not able to use a recent restore point though. On rebooting I would be faced with the same problem.
I have updated all my security programs in safe mode with networking and run them but so far they have found nothing.
I have used Microsoft Security Essentials
Malwarebytes (the database was corrupted and was downloaded again)
WinPatrol has not notified me of any suspicious activity
in addition I have run a couple of online scans (I forget which ones)
I have run start up repair but apparently this has not fixed my problem. I am using online armour as a firewall. I am not convinced that I have any virus and my security is pretty comprehensive but I am at a loss to what to try next and would appreciate some help if possible.
