What do i do now?

[PuddingBBT]

 I've updated the newest version of Avast, and it asked me to reboot. After reboot, it came to the desktop. Everything SEEMS fine, but when i click and start any program such as firefox, my computer just freeze there. I can move my mouse and click things but nothing would respond.

I tried to open task manager, but it wouldn't open.

I disabled Avast after resetting the computer, and then i system restored. Everything works now; programs open when i click them. But avast told me to reboot my computer, and i clicked no. So i dono what to do now, i think my computer is gonna crash again after reboot.

Need help fast please, thanx.

Operating system restart needed by avast message could be solved, in some systems, by deleting the file C:\Program Files\Alwil Software\Avast4\Setup\reboot.txt

If that doesn't resolve it check this:
You can also check this registry entry (right after computer restart):
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager, if it contains "PendingFileRenameOpertaions".

Check its contents and if there's only "reboot.txt" from avast4\setup folder, delete PendingFileRenameOperations, don't delete any other key.

Back-up (export) the registry key before you edit/delete, just in case.
