Installation problem : interactive logon process initialization failed

Avast Free Antivirus / Premium Security
1

Hi,

I’m running Windows Vista Pro on an Acer 5730.
I’ve just upgraded from Avast free to Avast Internet Security.
After rebooting, I get the following message : “interactive logon process initialization failed. See the event log”.

Avast free version was working fine.
I’ve already uninstalled Avast three times using the removal utility (Within Windows safe mode). I cleaned up the PC using CCleaner.

No way ! Each time the same message.

Thanks for help.
