Won't restart admin account

[sandryusky]

I am using windows 7 and received a "install updates msg fm avast" I clicked install now and it installed. Then it said Avast needs to restart your computer,  I said ok.  It restarts to my user screen. If I try to open my Administrator account, I get a blank screen with my cursor, nothing else comes up. I will let me open one of my other user accounts.  What can I do?

can you press ctrl+alt+del ?

if yes, chose start task manager, after that go to file, then select new task run and type explorer.

if this can solve the blank display you can do the scan.
